1-3 Composites Study
Abstract
This report identifies important practical issues related to 1-3 composites, based on (1) a quantitative comparison between solid ceramic, conventional 1-3 material, and an unfilled bar matrix in the context of transducers employing mass-loading to reduce the resonant frequency and (2) information gathered from researchers experienced in 1-3 composites in both low- and high-frequency applications. Findings include (but are not limited to): (1) Transducer configuration is critically importing in determining the applicability of 1-3 composite. (2) In a transducer in which the active material is sandwiched between mass elements, the filler in a 1-3 composite degrades performance with respect to an unfilled array of piezoelectric rods. (3) Self heating is only one of several obstacles to the successful use of PZT5H in high-power composites.
