Wear Behaviour of Epoxy Hybrid Particulate Composites

This paper presents the tribological behaviour of epoxy composites containing three different particulate fillers. The RT cured epoxy composites subjected to post cure cycle containing particulate Gr, SiC and Gr-SiC of length 25mm and diameter 10mm were the pin specimens and EN31 steel was the disc of the computerized pin on disc wear tester. The results show that the synergic effect of hybrid filler Gr-SiC is to improve the wear resistance when compared with that of Gr/SiC. The improvement in wear resistance for the composite containing 5% SiC 35% Graphite is 85% when compared with epoxy, 25% over composite containing 40% Gr and 36% over 40% SiC. The composites containing 5% Gr and 35% SiC exhibits highest wear resistance. (C) 2014 The Authors. Published by Elsevier Ltd.
