STUDY OF MECHANICAL PROPERTIES OF EPOXY BASED HYBRID COMPOSITES AT ROOM TEMPERATURE AND HARDNESS AT ELEVATED TEMPERATURE

ABSTRACT This study comprises of composite materials required for elevated temperatures for hardness property and at room temperature applications for other mechanical properties fabricated using hot air oven. Epoxy resin was used as matrix and glass fiber is used as reinforcement. Fillers like Al2O3, SiC, activated carbon powder and BaSO4 are the fillers used to bring in elevated temperature resistance for hardness and high mechanical strengths at room temperature. These composites are subjected to mechanical tests like wear, impact, tensile and hardness tests. Tensile, wear and impact energy were improved with variations in filler contents. Wear resistance also improved with increase in filler content SEM micrographs are used to explain the microstructure.
