The in-plane electrical conductivity: the rotation parameters effect on producing graphite/epoxy composites

Abstract

The rotation parameters used to produce graphite/ epoxy composites material is greatly determine the properties of in-plane electrical conductivity. However, the appropriate rotation parameters are different for each composition, conductive materials, and matrix used. In this study, variations of rotation parameters (250 rpm, 350 rpm and 450 rpm) and rotation time (5 min, 10 min and 15 min) with constant molding parameter such as molding temperature (150 0C), molding time (120 minutes) and molding pressure (50 kg / cm2) have been used to produce graphite/epoxy composites. The results showed that the highest in-plane electrical conductivity 65 S/cm on the resulting graphite/epoxy composites.
