摘要：

Composites consisting of fine, unidirectional ordered piezoelectric fibers in a polymer matrix offer a series of commercially relevant applications. Making use of PZT fibers with diameters in the range of 10-50 mu m improved functional properties of such 1-3 composites are expected stimulating the development of advanced ultrasonic transducers. The present paper reports on the preparation of 1-3 composites with different volume fractions of PZT(53/47) fibers and the characterization of their dielectric and piezoelectric properties. The experimental data were compared with results of finite element method modeling and parallel circuit modeling. (C) 1999 Elsevier Science Limited. All rights reserved.
