Studies On Wear and hardness Properties of Kevlar/E-Glass/Epoxy with SiC Reinforced Polymer Matrix Composites

Abstract: Over the last twenty to thirty years' composites materials has been used in engineering field. Composite materials possess high strength and high strength to weight ratio, and due to these facts composite materials are becoming popular among researchers and scientists. Wear test is one of the prime characteristic investigation test for determining the tribological behaviour of material under surface sliding and erosion. In the test sliding wear mechanism is adopted to study the material degradation under slides or contact surface using Pin-on-disc apparatus, in which materials are tested under dry sliding non-abrasion condition. Tribological characteristics of hybridized polymer matrix nano composites is determined by subjecting the composite specimens to sliding wear on Pin-on-disc sliding wear testing facility, the wear rate and co-efficient of friction were determined on ASTM G-99 Hardened steel disc, placing the fiber orientation of the composite specimen in parallel and normal to the sliding direction. The test was conducted on three samples of each composite specimen with different percentage integration of SiC viz, 0% 0.5%, 1.0% and 1.5% volume fraction of SiC reinforcement in composites under different loads.
