Abstract

A novel process of forming piezoelectric composites using tape cast sheets is reported. Composites with 2-2 and 2-0-2 connectivity were formed using sintered tape cast sheets of PZT-5H. The third phase in the form of powder included zirconia, alumina, or hollow and solid glass spheres. Electromechanical properties including d₃₃, d_h, K, ringdown time, and k_t were evaluated. The 2-0-2 composites showed a ringdown time up to 50% faster than 2-2 composites. The d_h of the 2-0-2 composites were about 20% higher than those of the 2-2 composites at equivalent PZT volume fractions
