Effects of material and test parameters on the wear behavior of particulate filled composites Part 1: SiC-epoxy and 13; Gr-epoxy composites

Studies were carried out on a (RT) cure epoxy (LY556xFE;HY951) composite system13; comprising of silicon carbide (SiC) and graphite (Gr) particulates. Results showed that13; the wear resistance and coefficient of friction of both the composites increased with sliding13; distance and contact load (contact pressure) for the range of filler contents (5x2013;40% wt) considered.13; The Gr-composite exhibited its distinct (superior) tribological feature compared to the13; SiC-composite. A wear endurance index has been identified from the experimental data, to serve13; as a parameter to assess the long term wear life (residual wear life) of these composites
