A model previously developed for pure 0-3 connectivity piezocomposites has been extended to 3-3 connectivity. This matrix method allows the prediction of the effective electroelastic moduli of a piezocomposite according to its connectivity. It is used to optimize composite performance by choosing the optimal constituents for each phase. A simple combination of the results for 0-3 and 3-3 connectivities allows the effective proportion of 3-3 connectivity to be defined in highly loaded 0-3 piezocomposites. This theoretical analysis has been used to evaluate effective proportions of 3-3 connectivity in five composite samples. The values obtained are shown to be a function of the ceramic volume fraction and fabrication process. The results of this study were used to optimize the fabrication process.
先前为纯0-3连通性压电复合材料开发的模型已扩展到3-3连通性。这种矩阵方法可以根据压电复合材料的连通性预测其有效电弹性模量。它用于通过为每个相选择最佳成分来优化复合材料性能。0-3和3-3连通性结果的简单组合可以定义高负载0-3压电复合材料中3-3连通性的有效比例。该理论分析已用于评估五个复合样品中3-3连通性的有效比例。所获得的值显示为陶瓷体积分数和制造工艺的函数。本研究结果用于优化制造工艺。
