Popis: Ceramic materials are being investigated by the Army for use in gun tubes. Compared to gun steels, ceramics possess superior wear resistance at ballistic temperatures, thus enabling improved lifetime for gun tubes. In order to survive the ballistic event, however, it is necessary to prestress the ceramic components with external sheathing to offset the tensile stresses in the tube wall that occur during the ballistic event. Previous sheathing designs for ceramic liners have included thermal shrink fits of tubular metallic components, steel wire overwrapped under high tension, and advanced fibrous composites overwrapped under high tension. In the present investigation, press-fitted composite sheaths are fabricated and tested with the purpose of validating a computer model applicable to the design of ceramic gun barrel liners.
