Studying the Effect of Glass - Fiber on Electrical Conductivity of Polyamide Composite Material

Abstract

The electrical conductivity of glass fibre reinforced polyamide composite materialswas investigated for both weight fraction of glass fibre and frequency. This study isfocused on various types of glass fibres (S, E&C) and different weight fractions (10,20, 30 &40) at frequencies (50, 500, 1000, 105 &106) Hz. The results exhibitedaddition glass fibre fillers on matrix material were apparent good electricalconductivity at high weight fraction comparing to their low percentage account of thefillers created conductive path in the matrix material, it reached to (2.52, 2.1&2.21)*10-10 S/cm for C-glass fiber, E-glass fiber and S-glass fiber; respectively at %40 weightfraction. Also that electrical conductivity increased with increasing in frequency due tocharges movement in the dielectric material.
