Abstract

This study was carried out to investigate the effect of adding mica (5, 10, 15, 20, 25 % vf) with variable particle size (35, 57, 70┬Ám) on the mechanical and electrical properties of the unsaturated polyester composites. Some mechanical tests were carried out like (impact strength, flexural strength) and dielectric strength. Flexural strength and dielectric strength were found to increase with filler concentrations whereas impact strength was found to decrease at higher concentrations for all particle size.
