N2 - In this work we present experimental and theoretical results on the low velocity impact of electrified carbon fiber polymer matrix unidirectional and cross-ply composites. A particular emphasis is given to the analysis of the influence of Joule heating on the alteration of the mechanical response of electrified composites. The results show that a short term current application leads to an increase in the impact resistance of electrified composites whereas a long term application of a DC current has a detrimental effect. A mathematical model to study the time dependent Joule heating in composites has been developed. The role of the current density and other material parameters has been elucidated.
