Abstract

The electrical property evolution of a metal/polyethylene terephthalate (PET) composite during tensile deformation was theoretically analyzed in this work. It was found that the resistance variation of a metal/PET composite during tensile deformation falls into two parts: before a crack appearance and after a crack appearance. Before a crack appears on the coated metal layer, the resistance variation complies with Ohm’s law. After that, the resistance variation of the metal/PET composite, on the whole, correlates with the elongation rate of the metal/PET composite in an exponent relation. In addition, the resistance variation of the Al/PET composite during tensile deformation was tested for verifying the correctness of the theoretical analysis.
