Abstract :
Zero-three lead zirconate-titanate (PZT) piezoelectric composites have been fabricated using powder prepared from ground sintered PZT ceramic of 160-230-μm particle size and thermoplastic ethylene-acrylic acid copolymers. After initial mixing, this allowed transducers to be fabricated by pressing at temperatures between 120 and 140°C. Samples were corona poled and evaluated for hydrostatic acoustic response using the figure of merit F=gh-dh/tanδ. Superior properties were achieved for specific polymers with the major improvements arising from low tan δ within the matrix
