Abstract:
A method of producing a composite ultrasonic transducer, which includes transducer elements that are dispersed in a plastic matrix, radiate essentially in the longitudinal direction, and comprise piezoelectric ceramic material, said method comprising the following steps:creating flat ceramic bodies, each of which has a plurality of spaced, slot-like openings;inserting a plurality of the ceramic bodies, with spacing there-between, into a casting mold;filling the casting mold with a plastic material;hardening the plastic material to form a molded composite block and removing the molded composite block from the mold; and,removing ceramic material present on opposite end surfaces of the molded composite block extending transversely to the longitudinal direction of the openings to the point that the plastic material imbedded in the openings is exposed at the narrow side edges of the openings.
