Studying the effect of glass-fiber on electrical conductivity of polyamide composite material

Abstract EN

The electrical conductivity of glass fibre reinforced polyamide composite materials was investigated for both weight fraction of glass fibre and frequency.

This study is focused 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 exhibited addition glass fibre fillers on matrix material were apparent good electrical conductivity at high weight fraction comparing to their low percentage account of the fillers 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 weight fraction.

Also that electrical conductivity increased with increasing in frequency due to charges movement in the dielectric material.
