Mastering of AC/DC Dielectric Characterization of Epoxy-Based Composites Crosslinked by Different Curing Agents

摘要

The electrical behavior of three different Epoxy-Based composite materials was studied by varying different test parameters. The electrode clamping force, the applied voltage, and the effects of the presence of water have been investigated in this work. A water activated electrical conductivity process was highlighted, at room temperature, in low frequency AC and in DC experiments for the material where clustering containing charges trapped associated with the polymerization is expected.
