The Production of Distorted 3-3 Hydrophone Composites from Reticulated Ceramics-Manufacturing Process Report,
Abstract
Reticulated ceramics have been in production for about 20 years. Annually, hundreds of thousands of square feet are produced with prices ranging down to twenty cents per square inch for some materials. This work was undertaken to apply reticulate ceramic processing techniques to piezoelectric ceramic-composite production and the subsequent production, testing, and evaluation of six hydrophones arrays. This first generation composite material has resulted in an rugged distorted 3-3 piezoelectric ceramic composite with decent acoustical properties. Modeling results suggests that simple modifications result in enhanced sensitivities and acoustics. However, a tradeoff has to be made in sensitivity to maintain strength at high pressures. A manufacturing scale-up as well as suggestions for a second generation material are presented. Composite costs are projected to be under $10/square inch in moderate volumes.
