Dielectric and Electrical Characterization Study of Synthesized Alumina Fibre Reinforced Epoxy Composites

Abstract

Fillers added to the matrix material help to enhance the properties of a composite. The present research investigation has aimed to the electrical study on synthesized alumina fibre reinforced epoxy composites at room temperature with different concentration of alumina fibre along with different frequencies. Decrease in dielectric constant and dielectric loss is found on increasing the frequency. Increase in ac conductivity has been found on increasing the frequency as well as concentration of filler. The resultant samples were prepared by hand lay technique. Cluster of alumina fibre is found on the surface of epoxy composite when examined by Scanning electron microscopy.
