Beschreibung
Zusammenfassung:	A bonded insulator flexural transducer for use in sonar applications includes a hollow metal tube having an inner surface, a segmented ceramic electromechanical driver disposed along an inner surface of the tube and a bonded insulator disposed between the segmented driver and the metal tube. The bonded insulator includes a high dielectric strength film, a layer of a binding fiber material, and a layer of epoxy. The dielectric film provides the electrical isolation between the driver and the shell and the binding fiber material provides a reliable bond by effectively trapping the epoxy between the driver and shell.
