Wave Absorption in Piezoceramic-Polymer Composites

Abstract

As new materials have become more difficult and expensive to develop, composites have received increased interest because they provide fewer development problems and often display better properties than single phased materials. Proper design of a composite involves several considerations and principles: properties of the constituents, connectivity of the individual phases, general phase connectivity, and possible cross-coupled properties. In the past, these principles have been profitably applied to optimizing electrical flux patterns and mechanical stress distributions to improve the hydrostatic strain and voltage coefficients of piezoelectric composites.
