Abstract
In this study, we investigate the effects of the thin-ply on electrical resistivity and its response to the tensile loading of carbon fiber reinforced polymers (CFRPs). Our results show that the resistivity in the thickness direction of the unidirectional laminate (UDL) made from thin-ply rises linearly at a small rate with the increase of the load until the load reaches 77.7% of the tensile strength calculated with the mix law of the composites, which is 1.43 times that of the thick-ply UDL. For thick-ply UDL, such linear response presents two phases. The resistivity increases at a small rate in the first stage in which the maximum load is low. The rate increased in the second stage is twice that of the first stage, and the threshold of the load corresponding to the stage is 54.4% of the tensile strength calculated with the mix law. It was found that the electrical resistivity of the CFRP in the thickness direction was related to the morphology of the resin-rich zone in between two plies and is less dependent of fiber volume fraction if fiber volume fraction is greater than a critical value in the composites.
