Dielectric Response during Cure of Particulate Composites of Epoxy Resin and Nickel Particles

The cure process of particulate composites consisting of an epoxy resin and nickel particles, was monitored dielectrically. The inclusion of metal powder in the resin causes a delay in the cure process. It also adds considerable conductivity and after gelation interfacial polarization phenomena are evidenced in the low frequencies, because of the interfaces introduced by the metal particles.
