Abstract

Composites with 3-1 connectivity were fabricated by impregnating an extruded, sintered honeycomb configuration of PZT with epoxy. The composites had lower density (≈ 3000 Kg/m3) and lower dielectric constant (≈ 400) than that of solid PZT. The maximum piezoelectric d̄33 coefficient of the composites was 350 pC/N, and the maximum hydrostatic d̄h 220 pC/N. ḡh and d̄hh of the composites were an order of magnitude higher than that of solid PZT. Considering the symmetry and phase connectivity of the individual phases in the composite, an explanation is given for the improved piezoelectric properties of the composites.
