ABSTRACTThe paper analyzes the issues relating to the applicability of innovative material systems for flexible composite armors. The authors made several samplings of aramid fibers (Kevlar 49) by replacing the epoxy resin base, which is often described in the literature, with the thermoplastic matrix - polyethylene (HDPE) and polypropylene (PP). The samples were fired with .38 Special Full Metal Jacketed (FMJ) ammunition produced by the S&B Company, and then the process of firing was modeled in the ABAQUS program. The advantages and disadvantages of the new material system including the possibility of its use in the construction of hybrid composite armors have been presented on the basis of the results of numerical analyses and ballistic tests.

Abstract In this study, ballistic performances of x wt.-% B4C (x = 5, 10, and 20) reinforced Al5Cu matrix composite samples were investigated as a monolithic and laminated composite armor component. Composite armor plates were produced by the powder metallurgy method. The prepared powders were pressed under 400 MPa pressing pressure. Green compacts were pre-sintered at 400 °C for 30 minutes in order to blow the lubricant. Subsequently, liquid phase sintering was performed at 610 °C for 210 minutes. In ballistic tests, 7.62 mm caliber armor-piercing bullets were used as the ballistic threat. In the ballistic tests of monolithic armors, only 10 mm thick powder metal composite plates were tested. In the ballistic tests of laminated composite armors, these powdered metal plates were layered with 10 mm thick alumina ceramic plate front layers and 10 mm thick AA5083 plates. Although all of the monolithic powder metal composite armors were penetrated, they showed multi-hit capability. All of the laminated composite armors provided full ballistic protection. It was determined that with the increase in B4C reinforcement rate, the ballistic resistance also increased due to the improvement in strength, hardness, and abrasive feature.

The present investigation is concerned with the development of fibre reinforced thermoplastic composite rods using braiding process. An innovative technique has been developed to produce composite rods with outer braided layer of polyester fibres and axially reinforced with high performance glass fibres. Polypropylene filaments which were introduced in to the core along with the glass fibres during the braiding process formed the thermoplastic matrix upon melting. A special mould has been designed for uniform application of heat and pressure during the consolidation of the composite rods as well as for the alignment of core fibres. The cross-section of composite rods was characterized with help of optical microscopy in order to see the distribution of core fibres and matrix. The effect of amount of glass fibres on the mechanical properties (tensile and flexural) of composite rods has been investigated and discussed.

Streszczenie:
Unidirectional abaca fiber reinforced thermoplastic starch composite was prepared via compression molding by varying the fiber volume fraction, compression pressure and fiber treatment. Factorial analysis at 95% confidence level has shown that changing fiber volume from 5% to 10% has a significant effect on the tensile strength of the composite. A treatment-pressure interaction was also found to have significant effect on the tensile strength of the composite. Result of tensile test showed that composite fabricated using 6.89 MPa (1000 psi) compression pressure, 10% fiber volume, and treated fibers exhibited the highest tensile strength of 19.73MPa while composite fabricated using 6.89 MPa (1000 psi) compression pressure, 10% fiber volume and untreated fibers exhibited only a tensile strength of 12.30 MPa. Scanning electron microscopy (SEM) on the transverse cross section has shown that alkali treatment was able to improve the interfacial bond between the fibers and the thermoplastic starch matrix resulting to an increase in strength of the composite fabricated at 6.89 MPa (1000 psi). However, using a compression pressure of 13.79 MPa (2000 psi) during fabrication induced damage, i.e. internal cracking, on the alkali treated fibers, thereby reducing the strength of the composite.

The utilization of coconut fibers as reinforcement in polymer composites has been increase significantly due to their low cost and high specification of mechanical properties. Whereas kevlar fibers has widely used as the core material in flexible body armors due to its great mechanical properties, such as high strength, light weight, good chemical resistance and thermal stability. The research work is concerned with the evaluation of high speed impact and flexural test of hybrid textile reinforced epoxy composites. Samples were prepared from coir yarn, kevlar yarn, interlaced of coir and kevlar yarn with different warp/weft orientation and pure epoxy as control specimen. The woven samples were produced using handloom and the composites specimens were prepared using hand lay-up technique. From the results obtained, it was found that woven kevlar composites samples displayed the highest impact properties while it exhibits the lowest flexural properties. Results also showed that the composite plate for woven coir yarn (warp) and kevlar yarn (weft) has the flexural strength and impact strength of 17 MPa and 67 kJ/m², which presented as the nearest properties to woven Kevlar composite respectively. These results indicate that coir as a natural fiber can be used as a potential reinforcing material for high impact resistance such as body armors in order to reduce the usage of synthetic materials whilst utilizing the natural resources.

The use of composite materials, mainly reinforced thermoplastic has increased on the polymer industry, mainly the polypropylene resins (PP) reinforced by glass fibers (GF). The ionizing radiation can promote alterations in the polymeric chains by scission and crosslinking reactions. The objective of this work is to study the effect of the ionizing radiation in the properties of the polypropylene long fiber glass reinforced thermoplastic. Pellets with 1,3 cm of length, contend 15wt% of the unidirectional long glass fiber were obtained by extrusion and, subsequently, the samples were molded by injection, irradiated and submitted to thermal and mechanical tests. The mechanical (tensile and impact) properties and thermal (HDT and Vicat softening temperature) of irradiated and non irradiated reinforced thermoplastic were determined. The doses of the irradiation of the samples were 30, 50 and 100 kGy in a source of 60Co. The results showed a reduction in the thermal and mechanical performances indicating a degradation of the polymeric matrix.

The objective of this study was to develop tests that could be used to characterize autohesive strength development in amorphous thermoplastic resins and fiber-reinforced thermoplastic prepregs. All tests were performed using polysulfone P1700 thermoplastic resin and AS4/P1700 graphite-polysulfone prepreg. Two test methods were examined to measure autohesion in neat resin samples. These included an interfacial tension test based on the ASTM tensile adhesion test (ASTM D897) and a fracture toughness test using a compact tension (CT) specimen (based on the ASTM toughness test for metals ASTM E399-83). The interfacial tensile test proved to be very difficult to perform and with an unacceptable amount of data scatter. The data obtained using the compact tension test were repeatable and could be correlated with temperature and contact time. Autohesive strength development in fiber-reinforced prepreg samples was measured using a double cantilever beam (DCB) interlaminar fracture toughness test. The fracture mechanisms were determined to be different in the healed DCB specimen than the virgin specimen due to resin flow at the crack plane during the healing tests. The CT test was found suitable for use in determining the autohesive properties and self-diffusion coefficient of neat resin. The DCB test, although not suitable for autohesive testing, indicated that repair of thermoplastic matrix composites is possible; however, the repair will not be as tough as the virgin material.

ENGLISH ABSTRACT: The South African manufacturing industry plays a pivotal role in the growth of its local economy. Modern manufacturing requirements include the ability to respond quickly to product variability, fluctuations in product demand and new process technologies. The reconfigurable manufacturing paradigm has been proposed to meet the demands of the new manufacturing requirements. In order to assess the feasibility of incorporating automated, reconfigurable manufacturing technologies into the production process of thermoplastic fibre-reinforced composite parts, a system, based on the thermoforming process, that implements these technologies was developed and evaluated. The assessment uses a seat pan for commercial aircraft as case study. Aspects that were addressed include the architecture, configuration and control of the system. The architecture and configuration addressed the sheet cutting, fixturing, reinforcing, heating, forming, quality assurance and transportation. The control, implemented using agents and based on the ADACOR holonic reference architecture, addresses the cell control requirements of the thermoforming process. An evaluation of the system’s reconfigurability and throughput is performed using KUKA Sim Pro. The evaluation of the system’s throughput is compared to the predicted throughput of the conventional technique for manufacturing thermoplastic fibre reinforced composite parts in a thermoforming process. The evaluation of the system’s performance show that the system designed in this thesis for the manufacture of a thermoplastic fibre-reinforced composite seat pan sports a significant advantage in terms of throughput rate, which demonstrates its technical feasibility. The evaluation of the system’s reconfigurability show that, through its ability to handle new hardware and product changes, it exhibits the reconfigurability characteristics of modularity, convertibility, integrability and scalability.
AFRIKAANSE OPSOMMING: Die Suid-Afrikaanse vervaardigingsbedryf speel 'n sentrale rol in die groei van die plaaslike ekonomie. Moderne vervaardiging vereistes sluit in die vermoë om vinnig te reageer op die produk veranderlikheid, skommelinge in die produk aanvraag en nuwe proses tegnologieë. Die herkonfigureerbare vervaardiging paradigma is voorgestel om te voldoen aan die nuwe produksie vereistes. Ten einde die uitvoerbaarheid van die integrasie van outomatiese, herkonfigureerbare vervaardiging-tegnologieë in die produksieproses van veselversterkte saamgestelde onderdele te evalueer, is 'n stelsel, gebaseer op die termo-vormingsproses, wat sulke tegnologieë implementeer, ontwikkel. Die assessering gebruik 'n sitplek pan vir kommersiële vliegtuie as gevallestudie. Aspekte wat aangespreek is sluit in die argitektuur, konfigurasie en beheer van die vervaardigingstelsel. Die argitektuur en konfigurasie spreek aan die sny, setmate, versterking, verwarming, vorm, gehalteversekering en vervoer van n veselversterkte saamgestelde sitplek pan in 'n termo-vormingsproses. Die beheer, geïmplementeer deur die gebruik van agente en gebaseer op die ADACOR holoniese verwysing argitektuur, spreek die selbeheervereistes van die termo-vormingsproses aan. 'n Evaluering van die stelsel se herkonfigureerbaarheid en deurvoer word gedoen met die behulp van KUKA Sim Pro. Die evaluering van die stelsel se deurvoer word vergelyk met die deurvoer van die konvensionele vervaardigingsproses vir termoplastiese vessel-versterkte saamgestelde onderdele in 'n termo-vormingsproses. Die evaluering van die stelsel se prestasie toon dat die stelsel wat in hierdie tesis ontwerp is vir die vervaardiging van 'n termoplastiese vessel-versterkte saamgestelde sitplek pan, hou 'n beduidende voordeel, in terme van deurvloeikoers, in wat die stelsel se tegniese haalbaarheid toon. Die evaluering van die stelsel se herkonfigureerbaarheid wys dat, deur middel van sy vermoë om nuwe hardeware en produk veranderinge te hanteer, die stelsel herkonfigureerbare einskappe van modulariteit, inwisselbaarheid, integreerbaarheid en skaalbaarheid vertoon.

State-of-the-art aircraft engine manufactures aim to reduce theirenvironmental impact steadily. Thereby they attempt to increase engineefficiency, use new renewable fuel sources and most importantly aim toreduce component weight. While Titanium, Aluminum and continuousfiber reinforced thermosetting composites and superalloys prevail in thecurrent material selection, the present work desires to raise awareness fora novel group of materials; short carbon fiber reinforced thermoplasticcomposites (SCFRTPs). In this kind of composite short fibers givedimensional stability and strength while the thermoplastic matrix ensuresthe physical properties, even at temperatures up to 300°C.Even though in some applications these materials offer great potential tosave weight and cost, it is not clear if their properties suffice to be used indemanding areas of the aero engine and if they are still able provide costand weight reductions there.The present work therefore investigated potential aero-engine componentsthat could be replaced by SCFRTPs. With literature, manufacturer data andmaterial and process modelling approaches, it is shown that SCFRTPsmechanical and physical properties suffice for the selected component.Further it is shown that cost reductions up to 77% and weight savings upto 67% compared to the Ti-6Al-4V baseline component are possible.

This work is concerned with preliminary studies on developing thermoplastic composite materials suitable for use in fused deposition modeling (FDM). Polypropylene (PP) strands reinforced with continuous thermotropic liquid crystalline polymer (TLCP) fibrils were generated in a novel dual extruder process. Strands were then re-extruded to form short fiber composite monofilaments that were used as feed stock in the FDM 1600 rapid prototyping system. Prototypes containing 40 wt% Vectra A were shown to have tensile properties twice those of parts built using acrylonitrile butadiene styrene copolymer (ABS), a commercially available material used in the FDM 1600 rapid prototyping system. It was also shown that the final mechanical properties of a composite prototype can be tailored to a specific application by adjusting the lay-down pattern, increasing the functionality of the prototype. In order to obtain the maximum tensile properties in these composite prototype, additional studies were performed to determine the effects of thermal and deformation histories on the mechanical properties of monofilaments that were re-extruded from long fiber TLCP reinforced strands. Strands were consolidated uniaxially at temperatures just above the melting point of the matrix in order to determine the effects of thermal history, and an approximate 20% reduction in tensile modulus relative to the modulus of the strands was observed. Monofilaments that could be used as feed stock in FDM were extruded from long fiber TLCP reinforced strands using a capillary rheometer in order to study the effects of capillary diameter, capillary L/D, and apparent shear rate on the tensile properties.

Streszczenie:
L’intérêt croissant de l’industrie pour les matériaux composites thermoplastiques est motivé par leurs propriétés de thermoformabilité, de recyclabilité ainsi que leurs capacités de cadences de production élevées. Le développement de matériaux pré-imprégnés thermoplastiques, apparus dès les années 1980, s’est imposé comme un moyen efficace de contourner les fortes viscosités des polymères utilisés en réduisant la distance d’écoulement des polymères à l’état « fondu ». Cette étude s’est plus particulièrement intéressée au développement de composites à base de tissus de verre et de carbone pré-imprégnés par un latex acrylique, le TPREG I. En outre, les propriétés mécaniques élevées des matrices acryliques, alliées à un coût relativement faible, en font un matériau intéressant, de nature à permettre un saut technologique dans la conception et la fabrication de composites structuraux à matrice organique. Notre étude s’est concentrée sur la mesure de l’adhésion à l’interface fibre/matrice acrylique car cette région est au cœur du transfert de charge de la matrice vers les fibres et conditionne donc les propriétés mécaniques du composite. Nous avons choisi d’évaluer l’adhésion interfaciale en combinant des analyses de mouilllage avec des tests mécaniques aux échelles microscopique et macroscopique. Le test micromécanique de la microgoutte permet de mettre en évidence le rôle central de l’ensimage des fibres sur la contrainte de cisaillement interfaciale. L’adhésion thermodynamique, déterminé par des mesures d’énergie de surface, est en accord avec la contrainte de cisaillement et souligne l’influence de la polarité de l’ensimage. A l’échelle macroscopique, les essais de traction hors-axe sur composites unidirectionnels permettant de solliciter l’interface en cisaillement quasi-plan ont mis en exergue une corrélation entre les échelles micro et macro. L’étude a également permis de dégager une forte augmentation de l’adhésion grâce à une modification de la matrice acrylique, ainsi qu’une dégradation des propriétés interfaciales à l’échelle micro par vieillissement hydrolytique. Cette étude constitue une première base de données concernant les propriétés interfaciales de composites thermoplastiques acryliques et démontre l’importance d’une étude multi-échelles dans la conception de nouveaux composites
The present study was initiated by the development of a new processing route, i.e. latex-dip impregnation, for thermoplastic (TP) acrylic semi-finished materials. The composites resulting from thermocompression of TPREG I plies were studied by focusing of interfacial adhesion. Indeed the fiber/matrix interface governs the stress transfer from matrix to fibers. Thus, a multi-scale analysis of acrylic matrix/fiber interfaces was conducted by considering microcomposites, as models for fiber-based composites, and unidirectional (UD)macro-composites. The study displayed various types of sized glass and carbon fibers. On one hand, the correlation between thermodynamic adhesion and practical adhesion, resulting from micromechanical testing, is discussed by highlighting the role of the physico-chemistry of the created interphase. Wetting and thermodynamical adhesion are driven by the polarity of the film former of the sizing. On the other hand, in-plane shear modulus values from off-axis tensile test results on UD composites are consistent with the quantitative analyses of the interfacial shear strength obtained from microcomposites. More specifically, both tests have enabled a differentiation of interface properties based on the fiber sizing nature for glass and carbon fiber-reinforced (micro-)composites. The study of overall mechanical and interface properties of glass and carbon fiber/acrylic composites revealed the need for tailoring interfacial adhesion. Modifications of the matrix led to successful increases of interfacial adhesion in glass fiber/acrylic composites. An additional hygrothermal ageing study evidenced a significant loss of interfacial shear strength at micro-scale which was not observed for UD composites. The results of this study are a first step towards a database of relevant interface properties of structural TP composites. Finally, the analyses of interfaces/phases at different scales demonstrate the importance of a multi-scale approach to tailor the final properties of composite parts

Le développement d’agents interfaciaux pour des matériaux composites renforcés de fibres est nécessaire afin d’obtenir des matériaux performants notamment pour l’industrie automobile. Le projet se concentre sur la synthèse d’oligomères à séquences contrôlées préparés par synthèse en phase solide par réaction d’amidification et de cycloaddition assistée par le cuivre entre un azoture et un alcyne pour introduire précisément des unités de phénylalanine et des groupes aliphatiques. Ces oligomères ont été testés comme agents interfaciaux pour des matériaux composites à base de polypropylène renforcés de fibres de Kevlar. Leur capacité à s’adsorber sur les fibres a été étudiée de façon qualitative par microscopie électronique à balayage et quantitative par analyse gravimétrique. Des expériences préliminaires sur des fibres de Kevlar traitées avec des oligomères synthétisés dans une matrice de polypropylène ont été réalisées pour estimer leur potentielle utilisation dans des matériaux composites
The development of interfacial agents for fibre-reinforced composite materials is needed to obtain performant materials especially for the automotive industry. The project focused on the synthesis of sequence-controlled oligomers prepared by solid phase synthesis using amidation and copper-assisted alkyne-azide cycloaddition reactions to introduce precisely phenylalanine and aliphatic building blocks. These oligomers were evaluated as potential interfacial agents for Kevlar fibre-reinforced polypropylene composite materials. Their ability to adsorb on the fibres was investigated qualitatively by scanning electron microscopy and quantitatively by gravimetric analysis. Some preliminary experiments on the Kevlar fibres treated with some of the synthesised oligomers in a polypropylene matrix were conducted to estimate their potential use in composite materials

Abstract Oil and gas exploration and exploitation in deep and ultra-deep waters challenges classical riser technology and configuration. New technologies, including carbon fiber as composite armors, influence weight and strength of the riser. This can allow for more simple configurations compared with conventional ones, simplifies installation procedures and eventually lead to reduced costs. The new fiber reinforced cross section sheaths requires new analytical models in the local stress analysis tools. The current paper explores efficient and accurate implementations of orthotropic laminate sheaths into classical cross section simulation tools. The model is based on a classic partition of the analysis scheme into a combined load and response model consisting of an axisymmetric and pure bending part. The suggested model is based on full 3D elasticity solution that allows for thick cylindrical laminates taking into account all stress and strain components. The model is compared with 3D Abaqus results for a number of different lay-ups and the results show excellent agreement with the more advanced 3D simulations in both axisymmetric and bending response modes. The laminate, a thermoplastic composite layer with carbon fibers, is used as a component in an unbonded flexible pipe. The cross-sectional analysis is thus performed in the classical way.

Streszczenie:
The braided fabrics are one of the typical textiles and have been expected to be an excellent performs for the reinforcements of composite materials. Fig.1 shows schematic drawing of a braided fabric. Braided fabrics are composed of Braided Yarns (BY) oriented diagonally and Middle End Yarns (MEY) inserted into the fabric in longitudinal direction. In previous study, it was clarified that the internal structures for the braided fabric were decided with 4 parameters; area and cross-sectional shape of braiding yarns, the braiding angle and distance between braiding yarns. And it have been suggested that internal structural parameters for braided fabric reinforced composites with thermo-setting resin are possible to be predicted. However in the case of braided composites with thermoplastic resin, impregnation mechanism of thermoplastic resin with solid state is completely different from that of thermosetting resin with liquid state. In order to predict internal structures of braided composites with thermoplastic resin, it is necessary to investigate the impregnation process or mechanism of thermoplastic resin in to fiber bundles apply enough heat on thermoplastic resin to be liquid state for good impregnation especially in the case of intermediate material such as comingled yarn, and etc. The purpose of this study is to predict the relationship between dimensional and internal structural parameters for braided fabric reinforced thermoplastic composite. The braided fabric was fabricated with intermediate material such as commingled yarns. During molding with heat and pressure, effect of molding time on the mechanism of impregnation and internal structural parameters were investigated.

This report is a literature review of several non-metallic material systems often used as alter-natives to steel pipelines. The pipeline systems reviewed are high density polyethylene (HDPE), fiberglass reinforced plastic (FRP), flexible composite and thermoplastic liners. This report is not intended to be a detailed guide or design manual on the use of the referenced materials for pipeline applications, rather an overall evaluation on the current state of these systems. Significant industry literature and documentation already exists on the design, manufacturing, installation, and operation of these pipelines. This information currently resides in pipe manufacturer's manuals and various industry standards and guides published by organizations such as ASTM International (ASTM), American Petroleum Institute (API) American Water Works Association (AWWA), and International Organization for Standardization (ISO). In Canada, the oil and gas industry pipeline code, CSA Z662-2015 (Canadian Standards Association, 2015). Users should frequently consult the manufacturers of the pipe products in use or under consideration for use for clarification and suggestions regarding the best practices, considerations and applications of the materials in question. In addition, pipeline operators should be aware of the applicable regulatory requirements in the jurisdictions they are operating within.
