Abstract

Abstract

The three-point test was carried out to test the modulus of rupture of PZT composite laminates. It is evident that the positive electric field can improve the modulus of rupture of PZT composite laminates but the negative one can decrease its modulus of rupture. A setup of in-situ AE measuring system was established to determine the different damage models of PZT composite laminates during the process of loading, and the damage model of PZT composite laminates was also verified by the scanning acoustic microscopic images.
