Preparation and Characterization of Graphite Flakes–Filled Polyester Composites

Abstract

The present article summarizes the experimental studies relating to the morphology, mechanical properties and electrical conductivity of graphite flakes filled unsaturated polyester composites. The study reveals that amorphosity is inversely proportional to crystallinity. The properties of the composites mainly depend on dispersion condition of filler particles, particle size and aggregate structure. The polyester graphite composite showed improved tensile modulus and Young's modulus in bending properties with increasing filler content. The electrical conductivity at different frequencies increased with increase in the filler content.
