Effects of Polarization orientation on the Effective Electromechanical Properties of 1-3 Piezoelectric Composites

摘要：

Piezoelectric ceramic/polymer composites have been widely studied because of their theoretical interest and technological applications.Piezoelectric composites with 1-3 connectivity have recently received increased attention due to their potential applications in underwater acoustics and biomedical imaging.1-3 piezoelectric composites have piezoceramic rods,embedded in a piezopassive or piezoactive polymer matrix.Their electromechanical properties of the piezoelectric composites can be tailored to meet specific applications.In addition,their flexibility offers an additional advantage over the brittle monolithic piezoelectric.In this paper,we study the effects of the variation in the polarization orientation and the volume fraction of 1-3 piezoelectric composites on their effective electromechanical properties and performance by using the micromechanics-based Mori-Tanaka method.For comparison,composites with piezoelectric ceramic and polymer matrix materials are considered.The results of the present research can provide useful information for optimizing the design of 1-3 piezoelectric composites for specific applications.
