Study the Effect of Volume Fraction of Mica With Different Particle Size on the Mechanical and Electrical Properties for Unsaturated Polyester Composites

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, 70μm) on the mechanical and electricalproperties of the unsaturated polyester composites. Some mechanical tests were carriedout like (impact strength, flexural strength) and dielectric strength. Flexural strengthand dielectric strength were found to increase with filler concentrations whereas impactstrength was found to decrease at higher concentrations for all particle size.
