In this work, an investigation of the effects of an electric current on the low velocity impact response of carbon fiber polymer matrix unidirectional and cross-ply composites carrying an electric current is presented. Preliminary experimental results show that a short-term application of the DC electric current leads to an increase in the impact resistance of composites, whereas a prolonged application of the current induces a significant heating in the electrified composites and has rather a detrimental effect. The analysis focuses on elucidating the roles of current intensity, duration, and associated current-induced heating in alteration of the composites response. The contributions of Joule heat and contact resistance heat are particularly highlighted.
