High Frequency Electrical and Magnetic Properties of Al/Epoxy Composites Prepared by Insulation Coating Process

Abstract:

Al/Epoxy composites with different Al content were prepared by insulation coating process including high energy ball milling and hot press. The electrical properties and magnetic performance including ac conductivity, permittivity, reactance and permeability were investigated in detail. The frequency dispersions of ac conductivity followed the power law, indicating the hopping conduction behavior. The real part of permittivity for composites increased with higher Al content, which was attributed to the more interface between Al and epoxy. Besides, the real part of the relative permeability decreased with higher Al content in high frequency.
