Abstract

This paper reports the tensile properties of epoxy filled with micro particulates of Gr and SiC as mono and hybrid fillers. The particulate content was varied from 10% to 40% in steps of 10% up to 40% for both types of fillers. The reinforced SiC fillers in epoxy shows improvement in mechanical strength while Gr fillers and hybrid (Gr-SiC) fillers filled epoxy show a decrement in tensile strength of composites. The tensile moduli of the filled composites increases with increased filler fraction and are higher than the neat epoxy. Further, it is observed that, the filler fraction and filler type has significant role in strength of a particulate filled epoxy composites. The experimental strength and modulus of epoxy composites is compared with analytical equations.
