Effect of Nano Filler Reinforcement on MechanicalProperties of Epoxy Composites

摘要

Nano-sized functional fillers, such as Nano-clay (N-C) and Nano-calcium carbonate (N-CC), have attracted a great deal of awareness due to their unexpected intrinsic properties. Extensive research has been done on clay material for epoxy Nanocomposites but only a few have ventured into a comparison with other Nanofillers. In this paper, a study has been made of the mechanical properties of epoxy containing N-C and N-CC fillers. These composites were studied for their mechanical properties such as hardness, tensile, flexural and impact strength as per ASTM standards. Fraction of void cohort in the samples was quantified following the rule of mixture. Experimental results demonstrated that incorporation of N-C fillers expanded the hardness, impact strength and module of epoxy Nanocomposites. However, the tensile and flexural properties have shown declining trend for N-C/N-CC Nanocomposites. The morphological and fractographic features were examined utilizing scanning electron microscopy.
