Abstract
A sonic window suitable for use in sonar applications wherein an elastomer such as natural or synthetic natural rubbers, a low air entrapping fiber or fibril used for reinforcement, fillers, and thermosetting resins are formed into desired window configuration. The low air entrapment associated with the fiber or fibrils produces a remarkably sonicly transparent window.
