Axially Distorted 3-3 Composite for Hydrophone Applications.

Abstract

During the period from September to December 1992, progress has been made in initiating contact with the subcontractor, Hi Tech Ceramics, Inc., literature surveys, and in material and supply procurement. This includes design and fabrication of test and evaluation equipment and raw material purchase. A foam distortion technique which will allow repeatable and measurable modification of the foam macrostructure has been identified. An apparatus for evaluation of the distortion parameters has been fabricated and is nearly ready for testing. Some qualitative macroscopic evaluations of a distortion foam have also been made. A test chamber in which the hydrostatic response of the composite samples up to 1000 psi has been designed and fabricated. Problems with the raw material supplier have caused a significant delay in delivery of the PZT powder which has severely impacted the baseline sample fabrication schedule.
