Abstract
The drive for a rapid development of composite materials stems from the need for a combination of desirable properties that often cannot be obtained in singlephase materials. Electroactive composites consisting of a ferroelectric ceramic powder and an electrically inert polymer phase offer substantial advantages for the design and production of special purpose transducers.
0-3 composites have been prepared using a silicone rubber as the three dimensional inert polymer matrix. The poling characteristics are described along with the moisture uptake properties and its effect on piezoelectric voltage sensitivity and dielectric loss factor (tan(δ)). Comparisons are made where possible with an epoxy resin composite
