Abstract: In the present study, composite materials required for elevated temperature applications were fabricated using vacuum bagging technique. Epoxy Resin (ER-VP401) was used as the matrix and Glass fibre was used as reinforcement. SiC, Al2O3 and others were used as fillers to bring in elevated temperature resistance. These composites were subjected to mechanical tests like Tensile, Hardness and Impact test. Tribological tests like two body abrasion and Pin on disc (POD) were carried out. Tensile strength, hardness and impact energy were improved with increase in fillers content. Wear resistance also improved with increase in percentage of fillers substantially. SEM micrographs are used to explain the mechanism of the material strengthening at elevated temperatures.

Keywords: Epoxy resin, Glass Fiber (GF), Al2O3, SiC, Elevated Temperature Resistance.
