Effect of Nylon-66 Interleaving on Dielectric Properties of Carbon-Epoxy Composites

This paper discusses the dielectric properties epoxy carbon fiber composites with interleaving of nylon-66 nano-fibers. The non-interleaved and interleaved composites are observed to exhibit a relaxation peak at 100 kHz. The variations in the complex electric modulus reveal that interfacial relaxation of Maxwell-Wagner-Sillars type exists in the composites. The ac conductivity of the non-interleaved composite is explained using the Universal power-law. The conduction mechanism of the interleaved composites is attributed to the long-range diffusion of ions.
