Abstract
A replication process was used to fabricate woven PZT/polymer composites. Fabric templates consisting of woven carbon fiber were impregnated with PZT by soaking it in a solution containing stoichiometric amounts of dissolved lead, zirconium, titanium and niobium. Heat treatment burned out the carbon, leaving a PZT replica with the same form as the initial carbon weave. To form composites, replicas were sintered in a controlled atmosphere and backfilled with epoxy polymer. The process was attempted with as-received activated and nonactivated carbon fabrics, as well as those fabrics pretreated with hydrogen peroxide. Average d/sub 33/=90 pC/N, g/sub 33/=211 mV-m/N, and d/sub h/g/sub h/ hydrophone figure of merit of 2100*10/sup -15/ m/sup 2//N are reported for woven PZT/polymer composites.<>Keywords
