Abstract (sommario):

The study for strength calculation of one way fiber-reinforced composites and the study measuring precisely fiber orientation distribution were presented. However, because the DB that can predict mechanical properties of composite material and fiber orientation distribution by the fiber content ratio was not constructed, we need the systematic study for that. Therefore, in this study, we investigated what effect the fiber content ratio and fiber orientation distribution have on the strength of composite sheet after making fiber reinforced polymeric composite sheet by changing fiber orientation distribution with the fiber content ratio. The result of this study will become a guide to design data of the most suitable parts design or fiber reinforced polymeric composite sheet that uses the fiber reinforced polymeric composite sheet in industry spot, because it was conducted in terms of developing products. We studied the effect the fiber orientation distribution has on tensile strength of fiber reinforced polymeric composite material and achieved this results below. We can say that the increasing range of the value of fiber reinforced polymeric composite’s tensile strength in the direction of fiber orientation is getting wider as the fiber content ratio increases. It shows that the value of fiber reinforced polymeric composite’s tensile strength in the direction of fiber orientation 90° is similar with the value of polypropylene’s intensity when fiber orientation function is J= 0.7, regardless of the fiber content ratio. Tensile strength of fiber reinforced polymeric composite is affected by the fiber orientation distribution more than by the fiber content ratio.

Abstract (sommario):

The sandwich composite polymeric products have a wide utilization in various fileds like aircraft and automotive construction, load bearing structures, sports equipment, more specifically, wherever weight-saving is required. Sandwich composites polymeric products represent excellent examples of the potential offered by composite materials. The combination of two composite faces and a lightweight polystyrene core allows obtaining a high flexural stiffness with a weak mass. This paper deals with the analysis of the structural and mechanical behavior properties of the core, adhesive and faces, for sandwich composite polymeric products. There are also presented the investigation results on how different specific factors like: mechanical and structural behavior, interface between the faces and core, constant force resistance in time, the reinforcing elements (fiber glass), the polyester core do influence the machinability of sandwich composites polymeric products..

Abstract (sommario):

This paper presents experimental results on the mechanical performance of advanced carbon/epoxy composites with embedded polymeric films. The composite laminates with polymeric films, which are potentially used as a sensor/actuator carrier for structural health monitoring applications, were investigated under various mechanical loadings including low velocity impact, single lap shear and short beam shear. The preliminary work showed that embedment of those polymeric films does not degrade, but could significantly improve, the mechanical properties of the composite laminates.

Abstract (sommario):

A solid composite of desirable microstructure can be produced by curing a liquid polymeric suspension in an electric field. Redistribution effect of the field-induced forces exceeds that of centrifugation, which is frequently employed to manufacture functionally graded materials. Moreover, unlike centrifugational sedimentation, the current approach can electrically rearrange the inclusions in targeted areas. The electric field can be employed to produce a composite having uniformly oriented structure or only modify the material in selected regions. Field-aided technology enables polymeric composites to be locally micro-tailored for a given application. Moreover, materials of literally any composition can be manipulated. In this article we present testing results for compositions of graphite and ceramic particles as well as glass fibers in epoxy. Electrical and rheological interactions of inclusions in a liquid epoxy are discussed. Measurements of tensile modulus and ultimate strength of epoxy composites having different microstructure of 10 vol% graphite, ceramic particles and glass fiber are presented.

Abstract (sommario):

Even though casein has an intrinsic potential ability to act as a flame retardant (FR) additive, the research regarding the FR performance of casein filled polymeric composites has not been thoroughly conducted. In the present work, two commercial casein products, such as lactic casein 720 (LAC) and sodium casein 180 (SC), were chosen to investigate their effects on the performances of the polypropylene (PP) composites. The melt compounding and compression moulding processes were employed to fabricate these casein-based composites. Ammonium polyphosphate (APP) was also selected to explore its combined effects in conjunction with casein on the composite’s flammability. The cone calorimeter results showed that the addition of casein significantly reduced (66%) the peak heat release rate (PHRR) of the composite compared to that of neat PP. In particular, the combination of LAC and APP led to the formation of more compact and rigid char compared to that for SC based sample; hence, a further reduction (80%) in PHRR and self-extinguishment under a vertical burn test were accomplished. Moreover, the tensile modulus of the composite improved (23%) by the combined effects of LAC and APP. The overall research outcome has established the potential of casein as a natural protein FR reducing a polymer’s flammability.

Abstract (sommario):

In the present investigations, Most of the engineering applications of metallic materials are replaced by polymeric based composite materials. Because of the low cost and accessible handling of polymer composite materials such as Acrylonitrile butadiene styrene (ABS) matrix materials are used to make the composites with additions of filler enhance the properties of the matrix materials. In the present study, ABS matrix material is used to make the composite materials by adding the Teflon materials. Investigations are carried out to find the enhancement of the composites' mechanical properties. Optimizing the process parameters is done to identify the composite's most optimum used to get composite with better mechanical properties. SEM analysis and wear Debris are investigated to study the microscopic surface nature and behavior of the composites.

Abstract (sommario):

The review article summarizes the results of studies conducted in the field of polymer composites obtained by various methods. An important industrial activity is structured around the development of polymeric materials and composites based on them. Composite materials having a matrix comprised of a polymeric material (polymers, oligomers, copolymers) are highly numerous and diverse. They are widely used in the industry for the manufacture of vitreous, ceramic, electrically insulating coatings, as adsorbents in the treatment of wastewater from heavy metal ions, and in the production of ion-exchange membranes. Composite materials have unique properties such as a large surface area, thermal and mechanical stability, good selectivity against various contaminants, and cost-effectiveness. The review presents the physicochemical and structural characteristics of composite materials based on synthetic polymers (polymer-carbon, polymerclay composites), polymeric heterocyclic and organosilicon compounds. Used across a variety of applications, polymer-carbon and polymer-clay composites are effective in removing organic and inorganic contaminants. However, when used as adsorbents for large-scale production, they have yet to achieve optimum performance. Hybrid materials obtained by the sol-gel method deserve special attention. This method can be conveniently used to influence the composition and structure of the surface layer of such materials as adsorbents of heavy and noble metals, catalysts, membranes and sensors for applications in biological antibiosis, ion exchange catalysis, etc. Such composites are characterized by their increased mechanical strength and thermal stability, as well as offering improved thermochemical, rheological, electrical and optical properties.

Abstract (sommario):

An aluminum mold was designed for fabrication of research quality composite tubes on a hot press (miniclave). This mold allows the pressure to be applied uniformly to the inner surface of a composite (prepreg tape) tube while a constant vacuum is also applied independently to the composite throughout the course of fabrication. With proper placement of stoppers and spacers inside the mold, various types of high quality unidirectional composites with fibers oriented either in the zero or 90 degree directions, respectively, were fabricated on a hot press. The mold design had less resin loss throughout fabrication compared to a conventional tubular mold. Physical and material tests have characterized the superior qualities of the resulting composite tubes.

Abstract (sommario):

In this paper polymeric particulate composites are studied (especially polypropylene (PP) matrix stuffed by rigid mineral fillers). Presently, polymeric particulate composites are frequently used in many engineering applications. The composite was modeled as a three-phase continuum – matrix, interphase and particle. The properties of the particles (size, shape) have a significant effect on the global behaviour of the composite. On the basis of fracture mechanics methodology the interaction of micro-crack propagation in the matrix filled by rigid particles covered by the interphase was analyzed. The effect of the composite structure on their mechanical properties is studied here from the theoretical point of view.

Abstract (sommario):

The welding of composites has become a crucial step in the production of complex composite parts. Typically, various welding and joining techniques are used to manufacture composite assemblies. However, ultrasonic welding is one of the most popular methods for welding thermoplastic composites and cannot be used for composites with a thermosetting matrix. This study employed ultrasonic welding process for fiber-reinforced polymer composites with a dynamic covalent adaptive network (CAN). We used a thermosetting polymeric network with an associative dynamic CAN, commonly known as vitrimers; the dynamic nature of these polymers makes them reprocessable, recyclable, and reusable. These polymers can be crosslinked like thermosets but flow as thermoplastics at elevated temperatures. Thin composites were fabricated by reinforcing glass fibers into the vitrimer polymeric matrix and then welded together using ultrasonic welding. This work represents the first demonstration of welding vitrimer glass fiber-reinforced composites (vGFRC). The vGFRC matrix employed transesterification molecular exchange reactions to initiate chain mobility, leading to interlocking and rearrangement reactions on the bondline during the welding process. We evaluated the mechanical, chemical, and morphological properties of welded lap joints before and after mechanical testing. Shear strengths of 10 MPa were observed for vGFRC, indicating good weldability properties of vitrimer surfaces. The reprocessable nature of these composites was evaluated by repeated testing of lap shear strength followed by ultrasonic welding over five cycles. Additionally, we evaluated the surface functionality and atomic percentage on the fractured surface using FTIR and XPS, respectively. This exciting discovery shows that high frequency and pressure can be used to weld and reprocess polymers with dynamic molecular networks by exploiting molecular fusion and rearrangement reactions at the bondline.

Abstract (sommario):

The quest for improvement of thermal conductivity in aerospace structures is gaining momentum. This is even more important as modern day aerospace structures are embedded with electronics which generate considerable amounts of heat energy. This generated heat if not dissipated might potentially affect the structural integrity of the composite structure. The use of polymer based composites in aerospace applications has also increased due to their obvious superior specific properties. But the thermal conductivity of the polymer matrix is very low and not suited for the design demands in aerospace applications. Several research studies have been conducted to improve the thermal conductivity of the polymeric composites. Different fillers have been used to improve the thermal conductivity of the polymeric matrix. Fillers may be in the form of fibers or in the form of particles uniformly distributed in the polymer matrix. The thermophysical properties of fiber filled composites are anisotropic, except for the very short, randomly distributed fibers, while the thermophysical properties of particle filled polymers are isotropic. Numerous studies have also been conducted in recent years where nanoparticles have been dispersed in the polymeric matrix to improve the thermal conductivity. Putman et al. [1] used the 3ω method to study the thermal conductivity of composites of nanoscale alumina particles in polymethylmethacrylate (PMMA) matrices in the temperature range 40 to 280 K. For 10% of 60 nm of alumina particle filler by weight (3.5% by volume) thermal conductivity of the composite slightly decreased at low temperatures. Whereas, above 100 K, thermal conductivity of the nanocomposite increased by 4% at room temperature. Kruger and Alam [2] studied the thermal conductivity of aligned, vapor grown carbon nanoscale fiber reinforced polypropylene composite. They measured thermal conductivity by laser flash instrument in the longitudinal and transverse directions for 9%, 17% and 23% fiber reinforcements by volume. The values of thermal conductivity as reported by them were 2.09, 2.75, 5.38 W/m.K for the longitudinal directions and 2.42, 2.47, 2.49 W/m-K for the transverse direction respectively, while the thermal conductivity of unfilled PP was 0.24 W/m-K. Exfoliated graphite platelets are another filler material of promise for improving the thermo-mechanical properties of the polymeric matrix. Aylsworth [3, 4] developed and proposed expanded graphite as reinforcement of polymers in 1910s. Lincoln and Claude [5] in 1980s proposed the dispersion of intercalated graphite in polymeric resins by conventional composite processing techniques. Since that time, research has been conducted on exfoliated graphite reinforced polymers using graphite particles of various dimensions and a wide range of polymers. Drzal et al. [6] have demonstrated the use of exfoliated graphite platelets to enhance the thermal and mechanical properties of polymeric resins. They concluded that composites made by in situ processing have better mechanical properties compared to composites made by melt-mixing or other ex situ fabrication methods due to better dispersion, prevention of agglomeration and stronger interactions between the reinforcement and the polymer. In the present study we use silver nano-filaments, nickel nano-filaments, alumina and exfoliated graphite platelets to enhance the thermal conductivity of an epoxy thermoset resin. The objective of this research is to identify the right filler to achieve the thermal conductivity as required by aerospace design engineers which is around 10 W/ m-K. An arbitrary filler loading of 8 wt% was chosen to compare the different fillers used in this study.

Abstract (sommario):

Selected fillers were incorporated to prepare polytherimide composite. The influence of fillers on the thermo-oxidative stability of the composite was studied by thermogravimetric analysis. The results showed that at optical filler loading and characteristics, the polymer composite became superior in its thermo-oxidative stability that is very promising in widening the window of service temperature of polyimides for extremely high temperature conditions where most polymeric composites fail. The findings should prove useful in developing high-temperature polymer composites for aerospace and electronics applications.

Abstract (sommario):

The properties of composite materials are strongly influenced by both the physical and chemical properties of their individual constituents, as well as the interactions between them. For nanocomposites, the incorporation of nano-sized dopants inside a host material matrix can lead to significant improvements in mechanical strength, toughness, thermal or electrical conductivity, etc. In this work, the effect of cellulose nanofibrils on the structure and mechanical properties of cellulose nanofibril poly(vinylidene fluoride) (PVDF) composite films was investigated. Cellulose is one of the most abundant organic polymers with superior mechanical properties and readily functionalized surfaces. Under the current processing conditions, cellulose nanofibrils, as-received and 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO) oxidized, alter the crystallinity and mechanical properties of the composite films while not inducing a crystalline phase transformation on the 𝛾 phase PVDF composites. Composite films obtained from hydrated cellulose nanofibrils remain in a majority 𝛾 phase, but also exhibit a small, yet detectable fraction of 𝛼 and ß PVDF phases.
