Abstract

The electromechanical properties and current-voltage characteristic of epoxy resin-matrix composites containing carbon black (CB) particles are experimentally studied. Non-Ohmic current-voltage characteristics of the specimens under an electric field with the intensity of 0-15 V/cm was observed. The resistance of the composites post-exposed to an electric field decreased dramatically. Meanwhile, the electromechanical properties of the specimens pre-exposed and post-exposed to the electric field changed significantly. A DC circuit model based on the experimental research is proposed. The occurrence of electrical breakdown induce the dramatic decrease of electric resistance of the composites post-exposed an electric field. The deformation of epoxy resin layer between two CB particles is employed to interpret the electro-mechanical properties of the CB filled epoxy composites.
