In the present study, novel ternary epoxy-graphene-MoS2 composites have been prepared. Graphene and MoS2 filler materials in 5, 10 and 20 wt.% have been utilized to prepare the epoxy composites, and physiochemical, thermal and tribological behaviors of the composites are described. Thermal stability of the prepared epoxy composites improves with an increase in particle concentration. Compared to the binary epoxy-graphene and epoxy-MoS2 composites, the ternary epoxy-graphene-MoS2 composite effectively reduces the friction coefficient and the wear rate. The estimated values of the friction coefficient and the wear rate of the ternary composites were found in the range of 0.0023-0.0048 and 1.22 x 10(-7)-1.44 x 10(-7) mm(3)/N-m, respectively. The excellent tribological and thermal decomposition properties of the prepared ternary composites make them suitable for light-weight automotive applications.
