Investigation on dielectric properties and behavior of thermoset epoxy composite based on cellulosic fibers has been carried on. Dielectric spectra were measured in the frequency range 0.1 Hz-100 kHz and at temperature intervals from ambient to 2008C. For the composite, four relaxations processes were identified, namely the orientation polarization imputed to the presence of polar water molecules in Alfa fiber, the a mode relaxation associated with the glass transition of the epoxy resin matrix, the relaxation process associated with conductivity occurring as a result the carriers charges diffusion noted for high temperature above glass transition and low frequencies, and interfacial or MaxwellWagner-Sillars relaxation that is attributable to the accumulation of charges at the Alfa fibers/epoxy resin interfaces. Dielectric relaxation analysis revealed evolution in water relaxation and it is thus concluded that the chemical treatment of the fiber can strongly influence the dielectrical properties and interfacial polarization processes in composites.

“…For nonpolar polymers the dielectric permittivity is independent of temperature; but in the case of strong polar polymers the dielectric permittivity increases as the temperature increases [16]. The independent trend of dielectric permittivity with frequency could be due to the nonpolar behaviour of Polyester chains [8].…”

The 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 and frequency (40 − 1 ). It was observed that the 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 in which the frequency exponent is in the range of 0.84 < < 0.98, and it was decrease with increasing woven roving fiber E-glass.

“…Researchers investigated dielectric behaviours of glass and jute fibres reinforced polyester hybrid composites and later on electrical properties of banana/glass hybrid fibre reinforced composites with varying hybrid ratios and layering patterns were analyzed (Fraga et al 2006;Joseph and Thomas 2008). In 2006, Ist time dielectric characteristics and volume resistivity of sisal-oil palm hybrid biocomposites investigated (Jacob et al 2006).…”
