A model is proposed to predict the electroelastic moduli of 0-3 connectivity piezo-composites from which parameters such as longitudinal wave velocity and thickness mode coupling factor can be deduced. The composite, a polymer loaded with ceramic particles, is represented by a unit cell, and a matrix manipulation is shown to be a practical way to perform a generalization of the series and parallel analysis used for 2-2 connectivity composites. The anisotropy of the ceramic phase is taken into account, and its effect on the properties of the composite is shown. The model is then used to optimize composite performance and to choose the two constituents through comparison of results obtained using several commercial polymers and ceramics.
提出了一个模型来预测0-3连通性压电复合材料的电弹性模量，由此可以推导出诸如纵波速度和厚度模式耦合因子等参数。该复合材料是一种填充有陶瓷颗粒的聚合物，用一个单位晶胞来表示，并且矩阵运算被证明是对用于2-2连通性复合材料的串联和并联分析进行推广的一种实用方法。考虑了陶瓷相的各向异性，并展示了其对复合材料性能的影响。然后使用该模型来优化复合材料性能，并通过比较使用几种商用聚合物和陶瓷所获得的结果来选择两种组分。
