Abstract

Considerations of the influence of crystal symmetry, macrosyrametry, and interphase connectivity have been used to explore possible macrostructures of interest as piezoelectric composites. Based on these design considerations, polymer-ceramic composites have been fabricated with 3-3 phase connectivity by the replication of natural template structures such as coral, or by a simplified fabrication technique of mixing volatilizable plastic spheres and PZT powders. 1-3 or 2-3 composites were made by perforated method. Polymer-Ceramic composites with 3-1 phase connectivity were made by embedding PZT rods or PZT spheres in various polymers. A modified connectivity model with 3-1-0 phase connectivity was introduced to improve the Poisson contraction problem found in 3-1 composites. In 3-1-0 composites voids were introduced into the polymer matrix to form a third phase which is isolated. All types of composites have been studied and it is shown that they have slightly lower permittivity, greatly improved dji and produce a much lighter material that can be adjusted to neutral buoyancy.
