Properties Of Composites

Fibre reinforced polymer composites play an incredible role in almost all spheres of day to day life and the field of carbon composites is one of the prime research area in recent decade. Polymers are mostly reinforced with fibre or fillers to obtain better mechanical properties. The properties of the polymer composites can be improved largely by varying the type of filler/fibre materials and its volume percentage. Composites properties depend on the size, shape and other physical properties of the reinforcements. A relative easy way to improve the mechanical properties of a polymer is the addition of filler materials. In all particulate filled systems, the adhesion between the matrix and filler plays a significant role in determining the key properties such as strength and toughness. The mechanical properties of composites are also influenced by the filler’s nature, size and distribution profile, aspect ratio, volume fraction, the intrinsic adhesion between the surfaces of filler and polymer. In this paper, the effect of filler material on mechanical properties of E-Glass fibre reinforced polymer has been studied out by varying filler materials. For these study three different types of specimens were prepared, viz FRP without filler material, the FRP with 10 volume percentages of carbon black and the FRP with 10 volume percentage of Fly ash as filler material. The polyester composites were fabricated by hand-layup method. Mechanical properties of the specimens are analyzed using computerized Universal Testing Machine as per ASTM D 638 standards. The resulting behavioral patterns of the FRP with filler material are listed and compared to those of the FRP without filler material. Mechanical properties such as ultimate tensile strength, percentage of elongation, yield strength, Poisson’s ratio and percentage reduction in area were found out.

With the lightning speed of technological evolution, the demand for high performance yet sustainable natural fibres reinforced polymer composites (NFPCs) are rising. Especially a mechanically competent NFPCs under various loading conditions are growing day by day. However, the polymers mechanical properties are strain-rate dependent due to their viscoelastic nature. Especially for natural fibre reinforced polymer composites (NFPCs) which the involvement of filler has caused rather complex failure mechanisms under different strain rates. Moreover, some uneven micro-sized natural fibres such as bagasse, coir and wood were found often resulting in micro-cracks and voids formation in composites. This paper provides an overview of recent research on the mechanical properties of NFPCs under various loading conditions-different form (tensile, compression, bending) and different strain rates. The literature on characterisation techniques toward different strain rates, composite failure behaviours and current challenges are summarised which have led to the notion of future study trend. The strength of NFPCs is generally found grow proportionally with the strain rate up to a certain degree depending on the fibre-matrix stress-transfer efficiency. The failure modes such as embrittlement and fibre-matrix debonding were often encountered at higher strain rates. The natural filler properties, amount, sizes and polymer matrix types are found to be few key factors affecting the performances of composites under various strain rates whereby optimally adjust these factors could maximise the fibre-matrix stress-transfer efficiency and led to performance increases under various loading strain rates.

Fibre Reinforced Polymer

Polymer composites have outstanding qualities such as high strength, flexibility, stiffness, and lightweight. Currently, research is being performed to develop innovative polymer composites that may be used in many operational situations and contain a variety of fibre and filler combinations. Banana fibre has low density compared to glass fibre and it is a lingo-cellulosic fibre having relatively good mechanical properties compared to glass fibre. Because of their outstanding qualities, banana fibre reinforced polymer composites are now widely used in various industries. The primary goal of this study is to determine the effect of the wt.% of banana fibre, the wt.% of SiC, and the wt.% of Al2O3 in banana fibre reinforcement composites on the mechanical and physical properties of banana fibre reinforcement composites. Tensile strength and flexural strength of unfilled banana fibre epoxy composite increased with the increase in wt. of banana fibre from 0 wt.% to 12 wt.%. Further, an increase in wt.% banana fibre drop in mechanical property was observed. It has been concluded from the study that the variation in percentage weight of filler material with fixed amount (12 wt.%) of banana fibre affects the mechanical properties of filled banana reinforcement composites. Optimum mechanical properties were obtained for BHEC5 (72 wt.% Epoxy + Hardener, 12 wt.% banana fibre and 16 wt.% Al2O3).

Purpose The mechanical and tribological properties of polymers and polymer composites vary with different environmental conditions. This paper aims to review the influence of humidity/water conditions on various polymers and polymer composites' mechanical properties and tribological behaviors. Design/methodology/approach The influence of humidity and water absorption on mechanical and tribological properties of various polymers, fillers and composites has been discussed in this paper. Tensile strength, modulus, yield strength, impact strength, COF and wear rates of polymer composites are compared for different environmental conditions. The interaction between the water molecules and hydrophobic polymers is also represented. Findings Pure polymer matrices show somewhat mixed behavior in humid environments. Absorbed moisture generally plasticizes the epoxies and polyamides and lowers the tensile strength, yield strength and modulus. Wear rates of PVC generally decrease in humid environments, while for polyamides, it increases. Fillers like graphite and boron-based compounds exhibit low COF, while MoS2 particulate fillers exhibit higher COF at high humidity and water conditions. The mechanical properties of fiber-reinforced polymer composites tend to decrease as the rate of humidity increases while the wear rates of fiber-reinforced polymer composites show somewhat mixed behavior. Particulate fillers like metals and advanced ceramics reinforced polymer composites exhibit low COF and wear rates as the rate of humidity increases. Originality/value The mechanical and tribological properties of polymers and polymer composites vary with the humidity value present in the environment. In dry conditions, wear loss is determined by the hardness of the contacting surfaces, which may not effectively work for high humid environments. The tribological performance of composite constituents, i.e. matrix and fillers in humid environments, defines the overall performance of polymer composite in said environments.
