In this study, the various epoxy/graphite particulate composites were prepared with different particulate fractions and were characterized for their mechanical, electrical, and morphological properties. The epoxy resin ( araldite (GY-257)) and hardener (HY-951) was used to prepare composite sheets by compression molding techniques. The graphite filler content was varied from 5 to 25wt% of the total matrix. These composites were then characterized for electrical properties and mechanical properties, i.e., tensile and flexural. There was a good adhesion between the filler and the matrix. The epoxy/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.
