An investigation on the tribological and mechanical properties of silicone rubber/graphite composites

Abstract

In this study, tribological properties and surface characteristics of silicone rubber/graphite (QMG) composites were investigated as a function of applied load, sliding velocity (1–5 m/s) and temperature. This study discusses a novel approach to improve the tribological properties of silicone rubber (QM). Inclusion of graphite significantly reduces the friction coefficient (̴40%) and specific wear rate of QM (50%). Wear mechanism involves formation of transfer film at the interphase between composite and steel counter surface. Tribological performance of QMG composites were found to be in agreement with its morphological, mechanical and dielectric properties.
