摘　　要：本文以丁腈橡胶为基体、钛酸钡(BaTiO_3)为功能相、导电炭黑为导电相制备了压电复合材料。对不同含量的压电复合材料进行了阻尼、吸声、力学性能测试。结果表明:BaTiO_3体积分数为60%条件下阻尼系数、硬度最大;在630Hz、BaTiO_3体积分数为50%条件下,吸声系数最大;随填料体积增大其拉伸强度、断裂伸长率均降低。This passage used nitrile rubber as the matrix, BaTiO_3 as function, conductive carbon black as conductive phase, and prepared piezoelectric composite material. On the different levels of piezoelectric composite damping tests, and optimized combination test its sound absorption performance. The results showed that it had the maximum hardness and damping coefficient under the condition of BaTiO_3 60%volume fraction; the maximum sound absorption coefficient under the condition of 630 Hz and 50% BaTiO_3 volume fraction; and packing volume increases, the tensile strength, elongation at break are lower.
