N2 - According to piezoelectricity and electrical conductivity theory, the ternary systempiezoelectric damping composites containing piezoelectric ceramic powder (PZT)/multi-walledcarbon nanotubes (MWNTs)/epoxy resin (EP) were developed. Through the conductive andmechanical performance test of composites, the paper showed the piezoelectric damping energydissipation mechanism of polymer composites. Results indicated that: the loss factor of materialswould increase with the increasing of PZT content.When the content of PZT exceeded a certain value,tanδ would increase dramatically. When the content of MWNTs is 2%, tanδ reached a high value.This meant composites played the role of shock absorbing by conducting electricity frompiezoelectric effect of PZT to external circuit.
