Studies on Rheological and Physical Properties of Metallic and Non-metallic Particulate Filled Epoxy Composites

Abstract

Studies were carried out on RT cure epoxy (LY556+HY951) composite system comprising of metallic and non-metallic fillers. The results of the studies carried out on the composites containing three distinctly different particulate fillers, representing metallic (Cu and Al), ceramic (SiC) and solid lubricant Gr materials showed that the viscosities of the composite formulations (slips) increased with increased filler loading for a given composite. The composite formulations containing Gr and SiC exhibited respectively the highest and lowest increments in their viscosities. Further, the densities of these composites increased with increased filler content, in the order of respective densities of the fillers used. Also, the hardness of the composites increased with the increased filler content, except for the Gr filled composites, which showed an opposite trend.
