Studies on Dielectric and Conductivity properties of Bio-Waste reinforced Polymer Composites

Abstract

In the present work we have prepared one pure epoxy and four bio-waste coir dust reinforced polymer composites by hand lay out method under the same conditions of temperature and pressure. Dielectric behavior of the composites were performed by using salortron 1296 dielectric interface equipment, in the frequency range 100Hz-1MHz and at temperature range of 30°C-150°C. The experimental results shows that, the dielectric constant (K), Dielectric loss (tan δ), and A.C conductivity (σ) increased and A.C resistivity (ρ) decreased with addition of coir dust in epoxy resin this is because of presents of water content and voids. It is also observed that the Dielectric and electrical properties of the composite material showed a strong dependence on frequency of applied electric field and testing temperature.
