  In this paper, variation in electrical properties of CFRP caused by
relatively low magnitude current impulses discharged through CFRP coupons are
reported, and internal changes of the composite, due to current impulses, are
studied. Based on electrical resistance measurements caused by these currents,
property changes in CFRP composite coupons of two different carbon ply
orientations are compared. Furthermore, it will be investigated if the changes
caused by current impulses are mainly focused in the region of the current
injection at the edges of composite coupons, or are they distributed uniformly
through the bulk of the composite.
