Thermal Stability and Tribological Behaviors of Tri-fillers Reinforced Epoxy Hybrid Composites

Abstract

The present works investigates the thermal stability and wear behaviour of tri-fillers reinforced hybrid composites. The Silica (S), Coconut shell (C) and Graphite (G) fillers reinforced homogeneous and functional graded epoxy composites are prepared by vertical injection molding techniques. The effect of filler contents, design parameters and its interaction on wear and friction behavior of SCG composites has been investigated. With help of Taguchi’s techniques, L27 orthogonal array, a series of experiments are planned and conducted on pin-on-disc tribo machine with three different loading of 10, 20 and 30 N, three sliding velocities of 1, 1.5 and 2 m/s by varying the G filler content of 10, 20 and 30 wt.% with constant weight fraction of S and C fillers of 10 wt.%. The results shows that the increasing the Gr content was increased the wear resistance and rate. The optimization techniques used to pridicated the composites parameters.
