摘　　要：基于压电导电原理,研制了一种新型吸声高分子复合材料,通过对PZT/CB/PVC高分子复合体系的压电性能、阻尼因子和吸声性能的测试分析,探讨了压电导电高分子复合材料体系中压电吸声途径的耗能机制,结论表明:导电相的添加,一定程度上提高了压电导电高分子复合材料的吸声性能。According to piezoelectricity and electrical conductivity theory, a new type acoustic absorbing composite was prepared. The piezoelectric, damping and acoustic absorption properties of composite PZT/CB/PVC were measured and analyzed. The energy dissipation mechanism of piezoelectric and acoustic absorption route of composite was studied. The results show that the acoustic absorption property of piezoelectric and electrical conductive composite is improved on certain level by the addition of electrical conductivity phase.
