摘要
In this study, three-phase piezocomposites are fabricated on the basis of the 1-3 composite structure and the cutting-filling method. The 1-3 piezocomposites are used with PZT-5A as the piezoelectrics and epoxy/silicone rubber as the matrix. The relationships between the performance parameters of the 1-3 composites and different ceramic volume fractions are analyzed via finite element simulation and experimental measurement. Composite samples with volume fraction of 0.20.8 are prepared through an experiment and tested using an impedance analyzer and a piezoelectric constant tester. Simulation results agree well with experiment results, thereby indicating that the composites have a high electromechanical coupling coefficient.
