A review on characteristics and recent advances in piezoelectric thermoset composites

Abstract

Piezoelectric thermoset composites (PTCs) are the class of material having the ability of transformation between mechanical energy and electric energy. In addition to having the advantages of high strength, easier processing, lower temperature, pressure requirement and unlimited storage, PTCs also have high stiffness, high elastic modulus and high strain coefficients. This review presents the advances and approaches used in PTCs and their applications. Various techniques, such as analytical, finite element and experimental methods for analyzing the coupled piezoelectric responses, are also reviewed. This paper also includes current applications of PTCs in strain sensing, vibration control, actuation, energy harvesting, structural health monitoring and biomedical fields. The studies of PTCs and its applications are in the emerging phase, and the review permits to find new notions for interface studies and modelling progresses for PTCs. In addition to that, these reviews pave the way for various research potentials towards the flourishing pertinent application zones of PTCs. Also, this review highlights the relevance of the particular research area and preliminary work under its different approaches, necessitates the need for more researches.
