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.
