STUDY OF THE CONDUCTIVITY OF VARIOUS SIZE FORMS CARBON PARTICLES USED AS FILLERS OF EPOXY POLYMER COMPOSITES

Abstract

The electrical conductivity of a polymer can be increased by the addition of a conductive material in particulate or fibrillar form. That are a lot of possibilities of conducting additives composites, for example chopped or milled carbon fibers, over multiwalled or singlewalled carbon nanotubes, graphite, graphene nanopellets and carbon black or fullerenes. The advantages of milled carbon fibers are affordability of starting materials. Presented work is focused on influence of size of short and small carbon fibers and fillers at changes AC conductivity of epoxy composites. The electrical properties for the matrix do not have significant effect on the electrical properties for the composite
