Abstract

The invention relates to piezoelectric composites and more particularly, but not exclusively, to a method of manufacturing a composite material in which a piezoelectric ceramic is dispersed as a powder within a polymer matrix. The method comprises forming a composite including a ceramic dispersed within a polymer matrix, partially curing the polymer matrix to a desired resistivity relative to the resistivity of the ceramic, applying a poling field to the composite to render the ceramic piezoelectric and increasing the resistivity of the polymer matrix by further curing. In one embodiment electrodes are bonded to the ceramic polymer composite by utilising the residual reactivity in the partially cured composite material to bond chemically the composite to the electrode material.
