Abstract

PZT/polymer composites having a 1–3 parallel connectivity were fabricated by impregnating a sintered, extruded honeycomb configuration of PZT with various polymers. The resultant composites were found to have densities less than 2900 kg/m³, a dielectric constant of ∼500 and a piezoelectric d₃₃ of ∼300×10⁻¹² C/N. The 1–3 connectivity increases the piezoelectric voltage coefficient (g₃₃) from 22×10⁻³ Vm/N (solid PZT) to ∼70×10⁻³ Vm/N. The composites have thickness mode electromechanical coupling coefficients (k_t) which are ∼25% greater than that of homogeneous PZT, and are readily adaptable for broad bandwidth operation. This combination of electromechanical properties makes these composites ideal for low voltage displacement and pulse echo applications.
