摘要
分析了水泥基压电机敏复合材料的可行性 ,包括复合材料的制备、极化和相容性等问题 .初步的分析结果和实验结果显示 :采用水泥基材料作为压电机敏复合材料的基体 ,可以有效解决机敏材料与混凝土母体结构材料之间的相容性问题 ,克服复合材料制备的困难和降低极化电压 ,从而提高极化效率和压电性能 。
Attention was focused on the study of the feasibility of the cement based piezoelectric smart composites, including problems in fabrication, polarization and adjustability of acoustic impedance of the composites. The results show that using cement based materials as matrix of piezoelectric smart composites can solve the mismatch problem, fabrication problem, and reduce the polarization voltage. This results in high polarization efficiency, good piezoelectric properties and low price.
