The existing experimental evidence suggests that organic matrix composites sustain less impact damage when an electric field is applied. The intricate interaction of an electrical field and mechanical load is governed by coupling of the mechanical and electromagnetic fields via the Lorentz force as well as by the processes undergoing at the microscopic level Joule heat, fiber-matrix interface changes, etc. The current work includes both experimental and theoretical investigations of the effects of an electric current on the impact response of carbon fiber polymer matrix composites.
