Full textAbstract:
Hybridization of natural fiber with synthetic fiber to reinforce polymer matrix composites is an effective way of increasing fatigue strength of composites with substantial amount of bio-based content. Flax is the strongest type of bast natural fiber, possessing excellent mechanical and damping properties. Fatigue properties of flax fiber hybridized with synthetic carbon fiber reinforced polymer matrix composites were studied. Fatigue properties of inter-ply hybrid flax-carbon fiber reinforced composite were compared to intra-ply hybrid flax-carbon fiber reinforced composites through tensile fatigue testing at 70% load of ultimate tensile strength and with a loading frequency of 3 Hz. For similar amount (by mass) of flax and carbon fiber, intra-ply flax-carbon fiber hybrid reinforced composite exhibited a very large increase (>2000%) in fatigue life compared to inter-ply flax-carbon fiber hybrid reinforced composites. Suitable hybridization can produce hybrid composites that are as strong as synthetic fiber composites while containing a high bio-based content of natural fibers.

Basalt fiber and carbon fiber hybrid with alternate stacking sequences reinforced epoxy composites have been developed to improve the toughness properties of conventional carbon fiber reinforced composite materials. For comparison, plain carbon fiber laminate composite and plain basalt fiber laminate composite have also been fabricated. The toughness properties of each laminate have been studied by an open hole compression test. The experimental results confirm that hybrid composites containing basalt fibers display 46% higher open hole compression strength than that of plain carbon fiber composites. It is indicated that the hybrid composite laminates are less sensitive to open hole compared with plain carbon fiber composite laminate and high toughness properties can be prepared by fibers' hybrid.

Full textAbstract:
Due exceptional properties such as its high-temperature resistance, mechanical characteristics, and relatively lower price, the demand for carbon fiber has been increasing over the past years. The widespread use of carbon-fiber-reinforced polymers or plastics (CFRP) has attracted many industries. However, on the other hand, the increasing demand for carbon fibers has created a waste recycling problem that must be overcome. In this context, increasing plastic waste from the new 3D printing technology has been increased, contributing to a greater need for recycling efforts. This research aims to produce a recycled composite made from different carbon fiber leftover resources to reinforce the increasing waste of Polylactic acid (PLA) as a promising solution to the growing demand for both materials. Two types of leftover carbon fiber waste from domestic industries are handled: carbon fiber waste (CF) and carbon fiber-reinforced composite (CFRP). Two strategies are adopted to produce the recycled composite material, mixing PLA waste with CF one time and with CFRP the second time. The recycled composites are tested under tensile test conditions to investigate the impact of the waste carbon reinforcement on PLA properties. Additionally, thermogravimetric analysis (TGA), X-ray diffraction (XRD), and Fourier-transformed infrared spectroscopy (FTIR) is carried out on composites to study their thermal properties.

Newer manufacturing techniques were invented and introduced during the last few decades; some of them were increasingly popular due to their enhanced advantages and ease of manufacturing over the conventional processes. Polymer composite material such as glass, carbon and Kevlar fiber reinforced composite are popular in high performance and light weight applications such as aerospace and automobile fields. This research has been done by reinforcing the matrix (epoxy) resin with two kinds of the reinforcement fibers. One weight fractions were used (20%) wt., Epoxy reinforced with chopped carbon fiber and second reinforcement was epoxy reinforced with hybrid reinforcements Kevlar fiber and improved one was the three laminates Kevlar fiber and chopped carbon fibers reinforced epoxy resin. After preparation of composite materials some of the mechanical properties have been studied. Four different fiber loading, i.e., 0 wt. %, 20wt. % CCF, 20wt. % SKF, AND 20wt. %CCF + 20wt. % SKF were taken for evaluating the above said properties. The thermal and mechanical properties, i.e., hardness load, impact strength, flexural strength (bending load), and thermal conductivity are determined to represent the behaviour of composite structures with that of fibers loading. The results show that with the increase in fiber loading the mechanical properties of carbon fiber reinforced epoxy composites increases as compared to short carbon fiber reinforced epoxy composites except in case of hardness, short carbon fiber reinforced composites shows better results. Similarly, flexural strength test, Impact test, and Brinell hardness test the results show the flexural strength, impact strength of the hybrid composites values were increased with existence of Kevlar fibers, while the hardness was decrease. But the reinforcement with carbon fibers increases the hardness and decreases other tests.

This paper aims to study the effect of different surface coatings of carbon fiber on the thermal, mechanical, and morphological properties of carbon fiber reinforced poly(phenylene sulfide) composites. To this end, unsized and different surface-coated carbon fibers were used. Prepared poly(phenylene sulfide)/carbon fiber composites were characterized by using Fourier transform infrared spectroscopy, differential scanning calorimetry, thermogravimetric analysis, tensile test, dynamic mechanical analysis, and scanning electron microscopy. Tensile strength values of the surfaced-coated carbon fibers reinforced poly(phenylene sulfide) composites are higher than the unsized carbon fiber reinforced poly(phenylene sulfide) composite. The highest tensile strength and modulus values were observed for the polyurethane-coated carbon fiber reinforcement. Dynamic mechanical analysis studies indicated that polyurethane-coated carbon fiber reinforced composite exhibited higher storage modulus and better adhesion than the others. Differential scanning calorimetry results show that melting and glass transition temperature of the composites did not change significantly. Scanning electron microscopic studies showed that polyurethane and epoxy-coated carbon fibers exhibited better adhesion with poly(phenylene sulfide).

Full textAbstract:
Abstract Carbon fiber reinforced composite materials offer greater rigidity and strength than any other composites, but are much more expensive than e.g. glass fiber reinforced composite materials. Continuous fibers in polyester give the best properties. The fibers carry mechanical loads, the matrix transfers the loads to the fibers, is ductile and tough, protect the fibers from handling and environmental damage. The working temperature and the processing conditions of the composite depend on the matrix material. Polyesters are the most commonly used matrices because they offer good properties at relatively low cost. The strength of the composite increases along with the fiber-matrix ratio and the fiber orientation parallel to the load direction. The longer the fibers, the more effective the load transfer is. Increasing the thickness of the laminate leads to a reduction in the strength of the composite and the modulus of strength, since the likelihood of the presence of defects increases. The aim of this research is to analyze the change in the mechanical properties of the polymer composite. The polymer composite consists of carbon fibers and epoxy resin. The change in compressive strength in the longitudinal and transverse directions of the fiber orientation was evaluated. At the same time, the influence of the wet environment on the change of mechanical properties of the composite was evaluated.

Full textAbstract:
This paper presents a study of the tribological properties of polymeric composite materials reinforced with unidirectional carbon fibers having stratified structure. Unidirectional reinforces carbon fiber materials are more effective if refer to specific properties per unit volume compared to conventional isotropic materials [. Potential benefits of carbon fibers composite materials are: high resistance to breakage and high value ratios strength/density; resistance to high temperatures; low density and high resistance to wear; low or high friction coefficient. The composites are complex and versatile materials but their behaviour in practice is not fully studied. For instance, polymeric composite materials reinforced with carbon fibers after being investigated in terms of wear, did not elucidate the effect of fiber orientation on wear properties [. Is therefore necessary to investigate the effect of carbon fibers orientation on the friction wear properties of the reinforced composite materials tested to adhesive and abrasive wear. Research work has been done with unidirectional composite materials having overlap 16 successive layers made from a polymeric resin and 60% of carbon fibers. The stratified structure was obtained by compressing multiple pre-impregnated strips, positioned manually. During this experimental work, three types of test samples were investigated: normal, parallel and anti-parallel, taking in consideration the carbon fibre orientation with respect to the sliding direction. The specific wear rate was calculated according to: the mass loss, density, the normal contact surface, the sliding distance and load rating. The friction coefficient is computed function to the friction load and loading value.

The comparison between carbon fiber reinforced different matrixes composites was studied in this work. Carbon fiber reinforced phenolic resin composite and carbon fiber reinforced benzoxazine resin composite were made by pultrusion processing. Bending strength test and charpy impact strength test were taken to characterize the toughness of different composites, and scanning electronic micro-scopy(SEM) was applied to evaluate the interfacial properties between carbon fiber and different matrixes. It was shown that compared with carbon fiber reinforced phenolic composite, carbon fiber reinforced benzoxazine composite had better performance in toughness and interfacial property. Bending strength and toughness were mainly depending on the property of matrixes, interfacial property was determined by carbon fiber and matrixes.

This study is to explore the changes in the performance of sports equipment under the action of carbon fiber reinforced epoxy composites. This paper studies the effects of carbon fiber reinforced epoxy composites in pole vault, bicycle, and tennis. The research results show that the performance of sports equipment based on carbon fiber reinforced epoxy composite materials has been greatly improved, with outstanding effects in terms of thermal properties, interface properties, mechanical properties, and fatigue resistance. Carbon fiber reinforced epoxy composite material damage expansion is divided into five stages: matrix cracking, interfacial degumming, delamination, fiber fracture, fracture. Therefore, carbon fiber reinforced epoxy composite materials are comprehensive for the improvement of sports equipment, which has greatly promoted the further development of sports. Carbon fiber reinforced epoxy composite materials can be promoted in other fields, thereby obtaining greater progress with help of high technology. The study of carbon fiber reinforced epoxy composites in this paper has a positive effect on subsequent research.

Full textAbstract:
Toray T300 PAN-based carbon fibers were surface oxidized in air at 300, 400 and 500 °C. The composition of surface was determined by X-ray photoelectron spectrometry (XPS), and the monofilaments of original carbon fiber and surface oxidized carbon fibers were tensile tested at room temperature. Three-dimensional carbon fiber reinforced BN-Si3N4 matrix composites were prepared by precursor infiltration and pyrolysis using a hybrid precursor mixed by borazine and perhydropolysilazane. With the increase of the oxidation temperature, the content of size on the surface of fiber reduces, and the tensile strength of carbon fiber declines. Carbon fiber oxidized at 400 °C has a 93% residual strength and the fiber oxidized at 500 °C is seriously decayed. The composite reinforced by original carbon fibers exhibits excellent mechanical properties, including high flexural strength (182.3 MPa) and good toughness; while the composite reinforced by 400 °C oxidized carbon fibers is weak (only 102.4 MPa) and brittle. The distinct difference of mechanical properties between the two composite is attributed to the change of the interfaces between carbon fibers and nitride matrices.

This manuscript is dealt with the synthesis of short carbon fibers reinforced polycarbonate polymer composite by using injection modeling technique. Four different composite materials were obtained by varying the carbon fibers weight percentage of 10, 20, 30 and 40%. The synthesized carbon fibers/polycarbonate composites were characterized for their morphological, mechanical and thermal properties by means of scanning electron microscopy (SEM), universal testing machine (UTM) and IZOD strength test. The resultant carbon fibers/polycarbonate composites exhibited excellent interfacial adhesion between carbon fibers and polycarbonate resin. The tensile properties were observed to be monotonically increases with increasing carbon fiber content in the composite resin. The tensile strength of carbon fiber/polycarbonate composites with the carbon fiber content 40% were increased about 8 times than that of the pristine polycarbonate matrix. The carbon fibers/polycarbonate composites with 40 wt.% of short carbon fibers exhibited a high tensile strength and thermal conductivity. The incorporation of carbon fiber in to polycarbonate resin resulted in a significant enhancement in the mechanical and the thermal behavior. These studies suggested that the short carbon fiber incorporated polycarbonate composite matrix is a good candidate material for many technological applications.

Fiber reinforced polymer (FRP) composites possess excellent specific strength, specific stiffness and controlled anisotropy for which these are extensively used in various engineering applications, like automobile industries, aerospace industries, marine industries, space industries, electronics industries and many more. Glass fibers (GF), carbon fibers (CF) and aramid fibers (AF) are common reinforcements for polymer matrix composites (PMCs). High mechanical properties and wear resistance behaviour of glass fiber reinforced composites are the premises for the current experimental research on the effect of fiber orientation on the tensile strength of the polymeric composite materials. The glass fiber reinforced epoxy resin composite was prepared by wet lay-up method, followed by thermal treatment.

This paper presents the water absorption and strength properties of short carbon fiber reinforced mortar (CFRM) composite. Four CFRM composites with 1%, 2%, 3%, and 4% short pitch-based carbon fibers were produced in this study. Normal Portland cement mortar (NCPM) was also prepared for use as the control mortar. The freshly mixed mortar composites were tested for workability, wet density, and entrapped air content. In addition, the hardened mortar composites were examined for compressive strength, splitting tensile strength, flexural strength, and water absorption at the ages of 7 and 28 days. The effects of different carbon fiber contents on the tested properties were observed. Test results showed that the incorporation of carbon fibers decreased the workability and wet density, but increased the entrapped air content in mortar composite. Most interestingly, the compressive strength of CFRM composite increased up to 3% carbon fiber content and then it declined significantly for 4% fiber content, depending on the workability and compaction of the mortar. In contrast, the splitting tensile strength and flexural strength of the CFRM composite increased for all fiber contents due to the greater cracking resistance and improved bond strength of the carbon fibers in the mortar. The presence of short pitch-based carbon fibers significantly strengthened the mortar by bridging the microcracks, resisting the propagation of these minute cracks, and impeding the growth of macrocracks. Furthermore, the water absorption of CFRM composite decreased up to 3% carbon fiber content and then it increased substantially for 4% fiber content, depending on the entrapped air content of the mortar. The overall test results suggest that the mortar with 3% carbon fibers is the optimum CFRM composite based on the tested properties.

Increasing applications of carbon fiber reinforced polymers exploiting its electrical properties demand a good understanding of the electrical conduction mechanisms of carbon fiber reinforced polymer. Resin-rich interface, which is not uncommon to exist between composite laminae, not only affect the mechanical properties, but also the electrical conduction behavior. This study focuses on the impact of resin-rich layer on the through-thickness resistivity of carbon fiber reinforced polymer. Electrical characterizations are carried out on dry fiber tow systems as well as cured composites. Through-thickness resistivity changes of dry fibers with the sizing are compared against fibers without the sizing layer, and cured composites with added resin-rich layer against the composite laminates without the resin-rich layer. A localized Joule heating theory is proposed to explain the difference in the electrical responses. The theoretical and experimental investigations should prove useful for the development of quantitative models with Joule heating to describe electrical resistivity behavior of carbon fiber reinforced polymer.

Among various composites available for use, carbon fiber reinforced composite is unique in its Nature. Carbon fiber is an extremely strong thin fiber made by pyrolyzing synthetic fibers, such as rayon, until charred. High Strength Composites are made from this fiber by using appropriate matrix material mostly Epoxy resins are used. High Strength, stiffness, light weight and high thermal conductivity are the main advantages over the other composites. Making products with one single composite sheet is not possible always. Some of the intricate or complex shape making is required for joining of two composite sheet. The composites joining can be done in three ways mainly Adhesive, Riveting and Hybrid. Based on the Review among all these joints adhesive joining gives better economic solution in joining. Experimental results point to significant influence of fibre on mechanical properties of sample.

Brominated, anodically oxidized, and pristine p-100 carbon fiber reinforced tin-lead alloy composites were fabricated by squeeze casting. The fibers were brominated by bromine vapor for 48 h and then desorbed at 200 °C in air for 12 h. The anodic oxidation treatment of fibers involved electrochemical etching in a dilute sodium hydroxide electrolyte for 3 min, or immersing in nitric acid for 72 h. The composites containing surface-treated carbon fibers had higher tensile and interlaminar shear strength than the ones containing pristine carbon fibers. The composite containing brominated carbon fibers had better tensile strength than the other two surface treatments.

This paper describes a theoretical approach to compare two types of fiber reinforced composite materials for femoral component of hip implants. The natural fiber reinforced composite implant is compared with carbon fiber reinforced composite and the results are evaluated against the control solution of a metallic implant made of titanium alloy. With identical geometry and loading condition, the composite implants assumed lower stresses, thus induced more loads to the bone and consequently reduced the risk of stress shielding, whilst the natural fiber reinforced composite showed promising result compared with carbon fibers. However, natural fibers, as well as carbon fibers, lack the power to improve interface debonding due to excessive loads in interface. Nevertheless, natural fiber reinforced composite could be an appropriate alternative given its capability of tailoring and achieving the optimal fiber orientation and robust design.

The internal structure of fiber reinforced geopolymer composite was investigated by microfocus X-ray computed tomography (µCT) under mechanical impact. µCT is a non-destructive, multi approach technique for assessing the internal structures of the impacted composites without compromising their integrity. The three dimensional (3D) representation was used to assess the impact damage of geopolymer composites reinforced with carbon, E-glass, and basalt fibers. The 3D representations of the damaged area with the visualization of the fiber rupture slices are presented in this article. The fiber pulls out, and rupture and matrix damage, which could clearly be observed, was studied on the impacted composites by examining slices of the damaged area from the center of the damage towards the edge of the composite. Quantitative analysis of the damaged area revealed that carbon fabric reinforced composites were much less affected by the impact than the E-glass and basalt reinforced composites. The penetration was clearly observed for the basalt based composites, confirming µCT as a useful technique for examining the different failure mechanisms for geopolymer composites. The durability of the carbon fiber reinforced composite showed better residual strength in comparison with the E-glass fiber one.

Carbon fibers were used to lay lengthways into three lays in jute fiber needled mat and the same fiber volume content of jute fiber needled mat were fabricated. Those two mats and the lengthways carbon fibers reinforced vinyl resin composites were made by VARTM. We made a comparison of the hybrid reinforced composites between the test value and the theoretical value which was predicted by establishing tensile and bending math-model and their mechanical properties were analyzed. The results show that there was a certain line between the theoretical value and the test value of the hybrid composites, so we can establish the mixing ratio between jute fiber and carbon fiber during the engineering application. Although the use of carbon fibers had greatly enhanced the tensile properties of hybrid composite, whose tensile strength and tensile modulus increased by 85.94% and 30.99% respectively than that without carbons, the bending model can’t be changed a lot.

Hybrid composites are made by combining natural and synthetic fibers with an effective matrix, which usually means they’ve received additional strengthening, such as epoxy, to create the additional material properties you can’t obtain on their own. To attain the desirable tensile modulus, compressive modulus, and so on, a fiber composite needs to be added to the FRP (Fiber Reinforced Polymer). Polymer matrix composites are light and cost-effective to manufacture, but they still friendly to the environment and have viable applications, which is why they are often used in various commercial applications. Unidirectional fibers and bidirectionally reinforced with epoxy (SikaDur is a composite medium) carbon fibers are two-way reinforced with unidirectional (use unidirectional) Before we developed test procedures for preparing the test specimens, the testing lab implemented the layup method according to ASTM standards. Ten separate stacking sequences were tested and four different intensity sequences were used in testing the compressive structures according to ASTM D15. The results of the study indicate that hybridization helps natural fiber-reinforced polymer composites to increase their mechanical properties We would use natural fibers rather than synthetic ones since the natural ones make comparable strength when hybridized with synthetic ones.

The composite materials are replacing the traditional materials, because of its superior properties such as high tensile strength, low thermal expansion, high strength to weight ratio. The developments of new materials are on the anvil and are growing day by day. Fiber composites such as Glass-Fiber Reinforced Polymers (GFRP) composites and Carbon-Fiber Reinforced Composites (CFRP) became more attractive due to their better properties for marine applications. In this paper, GFRP, CFRP and Hybrid composites are developed and their mechanical properties such as Hardness, tensile strength, compression strength, impact strength, toughness are evaluated. The study used to compare the effect volumetric fraction of fibers in order to improve strength and toughness, this done by using two types of fibers E-glass and carbon & two types of resins epoxy ( AralditeLY556 and Aradur HY951 ) and vinyl ester. In this experimental study, we found that high tensile strength, high specific strength, hardness and low density are obtained with carbon fibre reinforced composites, but high impact strength and toughness are obtained with glass fibre reinforced composites. Finally incorporate the result and try to find alternatives composites using for marine applications and obtain the best mechanical properties

Fracture mechanics and mechanisms of a carbon fiber reinforced carbon matrix lamina composite are studied. The importance of microfracture processes of first matrix cracking, fiber bridging, and fiber pullout processes for toughening C/C-composites is emphasized, and then, the fiber bridging process of the composite is mainly focused through the measurement of the R-curve. The fiber bridging tractions are estimated by the Dugdale approach from which the superb stress shielding and excellent notch tolerance of the composite are demonstrated.

Currently, the vast majority of composite waste is either landfilled or incinerated, causing a massive burden on the environment and resulting in the loss of potentially valuable raw material. Here, conventional pyrolysis and reactive pyrolysis were used to reclaim carbon fibers from aeronautical scrap material, and to evaluate the feasibility of using reclaimed carbon fibers in structural components for the automotive sector. The need for fiber sizing was investigated as well as the behavior of the fiber material in macroscopic impact testing. The fibers were characterized with the single fiber tensile test, scanning electron microscopy, and the microbond test. Critical fiber length was estimated in both polypropylene and polyamide matrices. Tensile strength of the fiber material was better preserved with the reactive pyrolysis compared to the conventional pyrolysis, but in both cases the interfacial shear strength was retained or even improved. The impact testing revealed that the components made of these fibers fulfilled all required deformation limits set for the components with virgin fibers. These results indicate that recycled carbon fibers can be a viable option even in structural components, resulting in lower production costs and greener composites.

This work tends to characterize the effect of carbon black nanofillers on the properties of the woven carbon fiber reinforced thermoplastic polymers. First of all, composites from nanofilled Polyamide 6 resin reinforced by carbon fibers were fabricated. Scanning electron microscopy observations were performed to localize the nanoparticles and showed that particles penetrated the fiber zone. In fact, by reaching this zone, the carbon black nanofillers create a connectivity's network between fibers, which produces an easy pathway for the electrical current. It explains the noticed improvement of the electrical conductivity of the carbon black nanofilled composites. Electrical conductivity of neat matrix composite passed from 20 to 80 S/cm by adding 8 wt% of carbon black and to 140 S/cm by adding 16 wt% of the same nanofiller. The addition of nanofillers modifies the heating and cooling laws of carbon fiber reinforced polymer: the nanofilled carbon fiber reinforced polymer with 16 wt% is the most conductive so it heats less. Based on these results, the use of the composite itself as an indicator of this mechanical state might be possible. In fact, the study of the influence of a mechanical loading on the electrical properties of the composite by recording the variance of an electrical set is possible.

Abstract The purpose of this research article is to show the effect of carbon nanotubes (CNTs) addition on fiber reinforced polymer matrix composites produced by the vacuum infusion method on tensile performance. In this study, glass, carbon, and fiber fabric reinforced polymer matrix composite plates were produced using glass, carbon and aramid fiber fabrics with the same weave type and similar areal density. Using the same production parameters, the composite plates reinforced with different fiber types were produced with CNTs addition by 0.5 wt% of total composite. Additionally, since it is thought that the effect of CNTs on performance in different fiber types may be different, hybrid fiber fabric reinforced composite plate material containing a composition of glass, carbon and fiber fabrics was produced and this material was produced with CNTs additive using the same production parameters as in previous fiber reinforced composite plate productions. In the study, composite plates with and without CNTs were produced in various compositions including glass, carbon, aramid, and hybrid fiber fabrics. As a result, CNTs reinforcement has increased the mechanical performance under tensile stress in glass, carbon, and hybrid reinforced fabric composite structures, but on aramid fiber, CNTs has decreased the performance.

ABSTRACTIn this work we report the fractographic study of polymer matrix composites specimens reinforced with glass and carbon fibers. Specimens of a polyester matrix composite with 30% of E-glass fibers are prepared and fractured in flexure mode. We also test an epoxy matrix composite with 30% carbon fibers, which is fractured in flexure mode. All specimens are manufactured based on the D790 ASTM standard for bending mode at room temperature. As an exception, the composites with epoxy matrix and reinforced with carbon fiber are cured in an autoclave. The most commonly observed fracture mechanisms are debonding in the interphase, delamination, Chevron lines, microbuckling, river patterns and radial fracture on the fibers.

Graphene nanoplatelets (GNPs) and carbon nanotubes (CNTs) are novel nanofillers possessing attractive characteristics, including robust compatibility with most polymers, high absolute strength, and cost effectiveness. In this study, an outstanding synergetic effect on the grapheme nanoplatelets (GNPs) and multiwalled carbon nanotubes (CNTs) hybrids were used to reinforce epoxy composite and epoxy/carbon fiber composite laminates to enhance their mechanical properties. The mechanical properties of CNTs/GNPs hybrids on a fixed weight fraction (1 wt%) with mixing different ratio reinforced epoxy nanocomposite, such as ultimate tensile strength and flexure properties, were investigated. The mechanical properties of epoxy/carbon fiber composite laminates containing different proportions of CNTs/GNPs hybrids (0.5, 1.0, 1.5 wt%) were increased over that of neat laminates. Consequently, significant improvement in the mechanical properties was attained for these epoxy resin composites and carbon fiber-reinforced epoxy composite laminates.

Full textAbstract:
The homogenization theory, used for the study of differential equations with periodic coefficients, with a rapid variation, is used in the paper for the analysis of the creep phenomenon of composite materials, reinforced with fibers. Generally, a polymer composite having a matrix with a viscoelastic response manifests a creep behavior. A good knowledge of mechanical constants allows us to predict the time response under the action of a load, which is important in engineering. The homogenization method is used to determine the engineering constants for a composite reinforced with carbon fibers. The method is applied for the particular case of fiber-reinforced unidirectional composites to obtain the equations that finally offer the required values. The epoxy matrix Fibredux 6376C is reinforced with carbon fibers T800 and the thermoplastic specimens made by APC2 material is reinforced with carbon fibers of the type IM6. The experimental results give a good concordance with the theoretical predictions.

This paper presents the development of a braided reinforced composite rod (BCR) able to both reinforce and monitor the stress state of concrete elements. Carbon fibers have been used as sensing and reinforcing material along with glass fiber. Various composites rods have been produced using an author patented technique based on a modified conventional braiding machine. The materials investigated were prepared with different carbon fiber content as follows: BCR2 (77% glass/23% carbon fiber), BCR3 (53% glass/47% carbon fiber), BCR4 (100% carbon fiber). BCRs have been tested under bending while the variation of the electrical resistance was simultaneously monitored. The correlations obtained between deformation and electrical resistance show the suitability of the rods to be used as sensors. The fractional resistance change versus strain plots show that the gage factor increases with decreasing carbon fiber content.

3D printed carbon fiber reinforced composites (CFRP) have shown great potential in lightweight application. Here, we report a prepreg carbon fiber reinforced polyamide composite by fused filament fabrication 3D printing process. The influence of layer thickness and carbon fiber layers on mechanical properties of 3D printed parts was well studied. With the incorporation of prepreg carbon fibers, the value of tension and flexural strengths of 3D printed CFRP parts could achieve 2.7 and 13.6 times compared to neat polyamide, respectively. Result illustrates that with the prepreg process the carbon fiber have good interface bonding strength with neat polyimide. This work could also be used for more 3D printing composite systems.

Carbon fiber reinforced aluminum matrix composite blocks and a pipe (as semi-product) were produced by pressure infiltration technique. In this paper the authors deal with the production method and investigations of the blocks and the pipe. In our composites AlSi12 eutectic aluminium-silicon alloy was used as matrix material. The reinforcements were ‘A’ and ‘B’ type carbon fibers (‘A’ having lower amorphous carbon content than ‘B’). The volume fraction of the fibers was outstanding – at least 55 vol%. Scanning electron microscopic investigations were done in order to observe the rather rough surface of the carbon fibres. X-ray diffraction and energy dispersive spectrometry was done in order to estimate the quantity of Al4C3 intermetallic phase at the carbon fiber/matrix interface region. The measurements showed that the quantity of Al4C3 strongly depends on the amorphous carbon quantity in carbon fibers. Much more Al4C3 was formed in the case of ‘A’ type reinforcement (less amorphous carbon), than in the case of ‘B’ type reinforcement (more amorphous carbon). The presence of Al4C3 crystals caused large scatter in the mechanical properties, the UTS was decreased, while the compressive strength was increased. Fracture surfaces were investigated: the composite showed rigid fracture.

Unidirectional and continuous carbon fiber tin-matrix composites were used for the packaging of the high-temperature superconductor YBa2Cu3O7–δ by diffusion bonding at 170 °C and 500 psi. Tin served as the adhesive and to increase the ductility, the normal-state electrical conductivity, and the thermal conductivity. Carbon fibers served to increase the strength and the modulus, both in tension along the fiber direction and in compression perpendicular to the fiber layers, though they decreased the strength in compression along the fiber direction. Carbon fibers also served to increase the thermal conductivity and the thermal fatigue resistance. At 24 vol. % fibers, the tensile strength was approximately equal to the compressive strength perpendicular to the fiber layers. With further increase of the fiber content, the tensile strength exceeded the compressive strength perpendicular to the fiber layers, reaching 134 MPa at 31 vol. % fibers. For fiber contents less than 30 vol. %, the compressive ductility perpendicular to the fiber layers exceeded that of the plain superconductor. At 30 vol. % fibers, the tensile modulus reached 15 GPa at room temperature and 27 GPa at 77 K. The tensile load was essentially sustained by the carbon fibers and the superconducting behavior was maintained after tension almost to the point of tensile fracture. Neither Tc nor Jc was affected by the composite processing.

Kevlar fiber and carbon fiber reinforced shape memory epoxy composites were prepared respectively. The fold-deploy shape memory properties of the composite system were studied at the temperature which was 30°C higher than the glass transition temperature of resin. The results shows that shape fixed rate and shape recovered rate of the composites are decreased with the increase of Kevlar and carbon fiber volume. The shape fixed rate of Kevlar fiber reinforced shape memory composite is higher than that of carbon fiber reinforced shape memory composite, but the shape recovered rate of the former is much lower than the latter.

Abstract: In Recent days, the natural fibres from renewable natural resources offer the potential to act as a reinforcing material for polymer composites alternative to the use of glass, carbon and other man-made fibres. Among various fibres, Hemp is most widely used natural fibre due to its advantages like easy availability, low density, low production cost and satisfactory mechanical properties. Composite materials play a vital role in the field of materials to meet the stringent demands of light weight, high strength, corrosion resistance and near-net shapes. Composite is a structural material that consists of two or more combined constituents that are combined at a macroscopic level and are not soluble in each other. Composites are having two phases that are reinforcing phase like fiber, particle, or flakes & matrix phase like polymers, metals, and ceramics. In this project an attempt is made to prepare different combination of composite materials using hemp/carbon fiber and Carbon nano tube reinforcement and vinyl ester as the matrix material respectively. Composites were prepared according to ASTM standards and following test are carried out Tensile, Flexural and ILSS test. The effect of addition of Carbon nano tubes in hemp/vinyl ester/carbon fibers has been studied & it has been observed that there is a significant effect of fibre loading and performance of hemp/carbon fiber reinforced vinyl ester based hybrid composites with improved results Keywords: Hemp fiber, Vinyl ester, Carbon fiber, Tensile, Flexural and ILSS Test

Fiber factor strongly influences the flexural properties of fiber-reinforced composites. Theoretically, strong fiber-matrix bonds combined with long fibers can produce high composite strength, while short fibers influence the ductility of the composite. Both conditions are obtained by aligning the fiber with the loading direction. In this study, an experimental study was conducted on the effect of fiber factors on the flexural strength and modulus of carbon fiber reinforced polypropylene. The fiber factors included in this study were: cryogenic fiber surface treatment, fiber length, and fiber orientation; each factor was divided into three levels. The relationship between the fiber factors and the responses was analyzed using the Response Surface Method (RSM) and Analysis of Variance (ANOVA). The results indicate that there is a good correlation between the predicted response values of the model and the results of the confirmation test. The fiber orientation has the most significant effect on the flexural strength of the composite. All fiber factors significantly affected flexural modulus, with fiber orientation as the most significant factor.

Natural fibers are potential alternatives to synthetic fibers. Sago palm is a new type of natural fiber and has the potential same as other existing natural fibers. In this study, the mechanical properties of sago palm/carbon fiber reinforced with epoxy hybrids were studied. Impact tests were conducted to study the impact properties of sago palm-carbon fiber-reinforced X hybrid composites. The hybrid composites contain woven sago palm fiber and carbon fiber reinforced with epoxy resin produced by the vacuum compaction method. Each sample was prepared with different volume fractions such as 40%, 64%, and 91% of composition sago palm fiber. After the preparation of composite material, mechanical properties tests were studied on the prepared sample. In addition, by using Scanning Electron Microscope Tests, the failure mode is investigated. It can be concluded that 40% of sago palm fiber contains the best impact behavior compared to 64% and 91% of sago palm fiber loading because it’s high in impact resistance.

Carbon fiber-reinforced plastic composites have been intensively used for many applications due to their attractive properties. The increasing demand of carbon fiber-reinforced plastic composites is driving novel manufacturing processes to be in short manufacturing cycle time and low production cost, which is difficult to realize during carbon fiber-reinforced plastic composites fabrication in common molding processes. Fused deposition modeling, as one of the additive manufacturing techniques, has been reported for fabricating carbon fiber-reinforced plastic composites. The process parameters used in fused deposition modeling of carbon fiber-reinforced plastic composites follow those in fused deposition modeling of pure plastic materials. After adding fiber reinforcements, it is crucial to investigate proper fused deposition modeling process parameters to ensure the quality of the carbon fiber-reinforced plastic parts fabricated by fused deposition modeling. However, there are no reported investigations on the effects of fused deposition modeling process parameters on the mechanical properties of carbon fiber-reinforced plastic composites. In the experimental investigations of this paper, carbon fiber-reinforced plastic composite parts are fabricated using a fused deposition modeling machine. Tensile tests are conducted to obtain the tensile properties. The effects of fused deposition modeling process parameters on the tensile properties of fused deposition modeling-fabricated carbon fiber-reinforced plastic composite parts are investigated. The fracture interfaces of the parts after tensile testing are observed by a scanning electron microscope to explain material failure modes and reasons.

Short fiber (basalt, carbon, ceramic, and glass) reinforced polypropylene hybrid composites were investigated to determine their mechanical properties in case of different reinforcing fiber types. The composites were reinforced with fibers and were produced by hot pressing after hot mixing techniques. Composite properties such as flexural strength, stiffness, static and dynamic fracture toughness were measured. It was realized that the main damage modes of the composites are fiber pullout and debonding. It was also found that basalt fibers are the most sensitive to the lack of the treatment with additives. These results were supported by scanning electron micrographs taken of the fracture surfaces.

This thesis use AOC15/50 blade as baseline model which is a composite wind turbine blade made of glass/epoxy for a horizontal axis wind turbine. A finite element modeling of composite wind turbine blade was created using the SHELL element of ANSYS. Then we study how to use the carbon fiber material replaces the glass fiber to make the hybrid blade, and find a suitable layup to improve the performance of the blade. The hybrid blade was made through introducing carbon fibers. Different models, with introducing different number of carbon fibers, 75% carbon fibers replace unidirectional glass fibers in spar cap of blade model which can achieve best structure performance. The wind turbine blades are often fabricated by hand using multiple of glass fiber-reinforced polyester resin or glass fiber-reinforced epoxy resin. As commercial machines get bigger, this could not to meet the demands. The advantages of carbon fiber composite materials are used by blade producer. Studies show that carbon fiber has high strength-to-weight ratio and resistance fatigue properties. Carbon fiber is mixed with epoxy resin to make into carbon fiber-reinforced polymer. Carbon fiber-reinforced polymer is the one of best blade materials for resistance bad weather. The stiffness of carbon fiber composite is 2 or 3 times higher than glass fiber composite [1], but the cost of carbon fiber composite is 10 times higher than glass fiber composite. If all of wind turbine blades are made of carbon fiber composite, it will be very expensive. Therefore carbon/glass fiber hybrid composite blade has become a research emphasis in the field of blade materials. This paper gives an example of finite element modeling composite wind turbine blade in ANSYS by means of the medium-length blade of AOC 15/50 horizontal axis wind turbine. This model can be directly used in dynamics analysis and does not need to be imported from the CAD software into finite element program. This finite element modeling of composite wind turbine blade was created using the SHELL element of ANSYS. Then we study how to use the carbon fiber material replaces the glass fiber to make the hybrid blade, and find a suitable lay-up to improve the performance of the blade.

In the recent years natural fiber reinforced composites are increasingly receiving attention from the researchers and engineers due to their mechanical properties comparable to the conventional synthetic fibers and due to their ease of preparation, low cost and density, eco-friendliness and bio-degradability. Natural fibers such as kenaf or flux are being considered as a viable replacement for glass, aramid or carbon. Extensive experimental studies have been carried out to determine the mechanical behavior of different natural fiber types such as the elastic modulus, tensile strength, flexural strength and the Poisson’s ratio. This paper presents a review of the various experimental studies in the field of fiber reinforced composites while summarizing the research outcome about the elastic properties of the major types of natural fiber reinforced composites. Furthermore, the performance of a kenaf reinforced composite plate is demonstrated using finite element analysis and results are compared to a glass fiber reinforced laminated composite plate.

Materials are usually stronger in fibrous form than in bulk form. Composites are made from bonding two materials, where the reinforcement contributes with the outstanding natural properties and the matrix supports the fibers by transferring the loads between them, besides protecting the fiber from the environment hazards. Consequently, creating a strong composite that can be used in various applications and situations. In this academic work it is going to be analyzed how the composite made from carbon fiber and epoxy thermoset matrix behaves in specific situations, by making them in two different manufacturing methods. In addition, the analysis is going to be made in the laboratories of the university and then compared with computer analysis.

Lightweight materials have recently received much attention for the fabrication of various components for industrial usage, particularly in the automotive and aerospace fields. Nowadays, though, recycling epoxy-based composite at the end of its life is very complicated but due to its lightweight and enhanced properties "fiber-reinforced" epoxy based polymer composites are most preferred materials instead of conventional heavy metals. The composites based on epoxy resins reinforced with high-performance fibers such as carbon fiber (CF) are in extensive use for industrial and structural applications. Moreover, Thermoplastics are less expensive, simple to work with and simple to recycle but they can’t give desired properties like Thermosets. The current study encompasses about CF and multiple attempts done over the decades to enhance the mechanical attributes of CF-reinforced thermo-set (epoxy) based composites and to understand the part of many parameters on their performance.

The goal of the present study is to fabricate the short fiber-reinforced metal matrix composites by accumulative roll bonding. Various mixtures of fibers including 100 glass, 95 glass/5 carbon and 80 glass/20 carbon (all in wt.%) were used as the reinforcement. In order to investigate the bonding quality at layer interface, the composites with various fiber mixtures were produced by cold roll bonding. The bonding strength of the composites under different processing conditions including the fiber mixture, reduction in thickness and post-rolling annealing was measured by the peeling test. The 95 glass/5 carbon mixture was used to fabricate the fiber-reinforced composite through accumulative roll bonding. The fiber distribution, tensile properties and wear behavior of the composite were investigated at various numbers of accumulative roll bonding cycle. It was found that during accumulative roll bonding, the fiber clusters were broken and fragmented into smaller pieces. Results showed that the tensile strength and wear resistance of the composite enhanced with increasing the number of accumulative roll bonding cycles.

The microwave absorbing properties of multi-layer carbon/carbon fiber composites, designed to function as radar absorbing structures (RAS), were studied over the X-band frequency range (8.0-12.4 GHz). High-frequency electromagnetic properties of various fibers (glass, carbon) and particulate filler (carbon black) are investigated as the major constituent materials of the RAS. Free space measurement depicts the perfect reflecting properties of carbon fiber composites (S11 = 0 dB, S21 = −40 dB). In the two-layered composite laminate (impedance transformer/reflecting substrate), the use of carbon black is necessary in the impedance transforming layer to obtain the high level of microwave absorbance and frequency tuning. Through the layer combination of the glass-fiber composite (thickness = 2.45 mm) containing carbon black (3% in weight) and carbon fiber composite as reflecting substrate, S11 can be reduced to as low as −40 dB at the frequency of 11.7 GHz, maintaining a low level of S21. The results demonstrate that RAS can be efficiently designed with the laminates of fiber reinforced composites with impedance transforming layer (glass fiber with suitable amount of carbon black) and perfectly reflecting substrate (carbon fiber).
