提出了一种预测中空压电纤维增强压电复合材料有效性能的模型。该模型是基于细观力学的代表性体积单元--修正同心圆柱体模型建立的。预测是五个有效的弹性常数，两个有效的压电系数，一个有效的介电常数，和两个热膨胀系数。对所选材料系统的数值结果进行了讨论。与有限元法的比较表明，非常好的协议。预测的有效性能的压电复合材料与中空纤维提供了增强的几个性能参数高达三倍的那些与固体压电纤维。
Presented is a development of models for predicting the effective properties of a piezocomposite reinforced with hollow piezoelectric fibers. The models are established based on micromechanics of representative volume element so-called modified concentric cylinders model. Predicted are five effective elastic constants, two effective piezoelectric coefficients, one effective dielectric permittivity, and two thermal expansion coefficients. Numerical results of a chosen material system are discussed. Comparisons with finite-element method show very good agreements. The predicted effective properties of the piezocomposite with hollow fibers provide the enhancement in several performance parameters up to three times as high as those with solid piezoelectric fibers.
