Electrostrictive Polymers for Advanced Sonar Transducers (EPAT). Volume 1

Abstract

The objective of this DARPA program is to develop high performance electroactive polymers and demonstrate the new polymers for underwater high-power sonar transducers. Through the support of this DARPA program, the electromechanical responses of the high energy electron irradiated copolymer have been improved significantly and PVDF based electrostrictive terpolymers with electromechanical performance better than the irradiated copolymers have been developed. The scale-up of the terpolymer production is current underway and the fabrication techniques for the multilayer transducer elements have been examined. Multilayer transducer elements have been fabricated by manually gluing the layer together and more recently at Electronic Concepts, Inc. by multilayer spiral roll. The preliminary test results on the transducer elements indicate that the transducers have the potential to be used for high power sonar transducer.
