Summary:采用切割-填充法制备了一种粗压电陶瓷纤维复合材料驱动器,该驱动器由叉指电极电路板、环氧树脂黏结层和粗压电陶瓷纤维复合材料层三部分组成。理论计算了粗压电陶瓷纤维复合材料的压电性能,并采用TF Analyzer 2000铁电分析仪和基于LabVIEW的动态应变采集系统测试了该驱动器的P-E回线和应变性能。结果表明：粗压电陶瓷纤维复合材料的理论压电常数d33和剩余极化强度Pr分别为634pC·N^-1和31.4μC·cm^-2。且在±1,000V正弦交变电压作用下,驱动器可以产生纵向和横向应变分别为30με和20με,即纵向和横向伸缩分别可达0.63μm和0.34μm。
Bibliography:The macro piezoceramic fiber composite actuators were fabricated by cutting-filling method. The structure of this actuator was made up of three parts, including interdigitated electrode plates, epoxy resin bonding layer and macro piezoceramic fiber composite layer. The piezoelectric properties of the macro piezoceramic fiber composite were calculated by theoretical model. The P-E loop and strain properties of the actuator were tested by TF Analyzer 2000 ferroelectric analyzer and dynamic strain acquisition system based on LabVIEW. The results show that the theory piezoelectric constants d33 and remanent polarization Pr of the macro piezoceramic fiber composite are 634pC N-1 and 31.4 μC cm^-2, respectively. Moreover, the actuator can also generate longitudinal strain of 30με and transverse strain of 20με at ±1,000V sinusoidal alternating voltage. That means, the stretching of longitudinal and transverse directions of the actuator is 0.63μm and 0.34μm, respectively.
