| 摘 要： | 金属颗粒分散压电陶瓷复合材料是一种新型的3-0型压电复合材料,其有效压电性能受金属相体积分数的影响.利用基于格林函数的有效介质理论,结合由于金属相的弥散导致压电陶瓷内电畴的取向分布变化,对金属相体积分数对复合材料有效压电性能的影响进行理论计算.结果表明,复合材料的有效压电性能随金属相体积分数的增加呈下降趋势,理论计算和文献报道的实测结果基本吻合,表明该方法能够预测压电陶瓷/金属复合材料体系显微结构与压电性能之间的关系.

| Abstract: | Metal-particle-dispersed piezoceramics are a new type of 3-0 piezoelectric composite.The volume fraction of metal particles has large effect on the piezoelectric properties of the composite.In combination with that metal particle dispersion can result in a change in orientation distribution of the electric domain in piezoceramics,the influence of the volume fraction of metal particles on the piezoelectric properties of the composite was calculated according to the effective medium theory based on Green's fu... |
