Abstract

The current work aims at experimental and theoretical investigations of the effects of an electric current on the dynamic mechanical response of carbon fiber polymer matrix composites. The existing experimental evidence suggests that exposure of a composite material to the electromagnetic field leads to changes in the material's resistance to the impact load and damage. To develop an understanding and to quantify the observed phenomena we have conducted a series of low velocity impact tests on electrified unidirectional and cross-ply carbon fiber reinforced polymer matrix composites. The results of measurements show considerable dependence of the impact-induced damage upon the intensity of the electric field applied to the composite. On the theoretical side, we are developing multi-physics models to investigate the effects of coupling of mechanical and electromagnetic fields in composites in order to elucidate the mechanisms behind the observed phenomena and provide guidelines for further studies.
