Abstract :
Using the chamber filled with the compressed silica oil, the variety of the dielectric and hydrostatic piezoelectric properties of 1-3-2 piezoelectric composite, which is a novel composite with PZT and epoxy, is studied in hydrostatic pressure surrounding. The 1-3 composite produced together with 1-3-2 composite by the same technics is measured in the same experiments with 1-3-2 composites. And the results have been compared between the 1-3 and 1-3-2 composites. The comparisons show that 1-3-2 composite has more mechanical stability than 1-3 composite when hydrostatic pressure varying from 0 MPa to 10 Mpa. The temperature stability is measured in a thermostat which provided the environment temperature varying from -60°C to 90°C. The results also show that 1-3-2 composite has more temperature stability than 1-3 composite.
