摘要

建立了1-3压电复合材料动力性能分析模型。基于该模型，可以评估1-3复合材料的有效参数及其与单胞长宽比的依赖关系。从模型中我们发现复合材料的机械质量因子可以低于陶瓷和聚合物。将预测结果与实验结果进行了比较，两者吻合较好。

Acoustic and electromechanical behavior of 1-3 piezocomposites for ultrasonic transducer applications

A model is derived for the analysis of the dynamic behavior of 1-3 piezocomposites. Based on this model, the effective parameters and their dependence on the aspect ratio of the unit cell of a 1-3 composite, can be evaluated. From the model we show that the mechanical quality factor of a composite can be lower than that of both the ceramic and polymer. The predictions are compared with experimental results and the agreement between the two is quite satisfactory.
