Abstract
The 𝑎𝑐 conductivity and dielectric permittivity of Polyester filled with different volume fraction of woven roving fiber E-glass prepared by a casting method has been measured, over temperature (23–100)𝐶𝑜 and frequency (40 𝑘𝐻𝑧−1 𝑀𝐻𝑧). It was observed that the 𝑎𝑐 conductivity increases with increasing frequency and temperature, whereas the dielectric permittivity for all samples shows almost independent on frequency, it was increases with increasing temperature and fiberglass volume fraction. The calculated values of the electrical conductivity shows it was obeys power law 𝐴𝜔𝑠 in which the frequency exponent 𝑠 is in the range of 0.84 𝑠 0.98, and it was decrease with increasing woven roving fiber E-glass.
