Abstract
A carbon and/or ceramic fiber reinforced carbon and/or ceramic matrix composite threaded member including a core, a fiber containing thread-defining element bonded to the exterior of the core and a reinforcing fabric layer securing the thread-defining element to the core. The thread-defining element may be an integral part of a tubular braided reinforcing fabric or applied to the core prior to application of a reinforcing fabric layer. Externally and internally threaded members and methods for their manufacture are described.
Claims37
An externally threaded composite member comprising an elongate core formed from at least one of carbon and ceramic material, a fiber containing thread-defining element formed from at least one of carbon and ceramic fibers bonded by one of carbonaceous and ceramic material to the exterior surface of the core, said thread-defining element helically extending around and along the lengthwise direction of the core and projecting radially outwardly of the core, and a reinforcing fabric layer formed from at least one of carbon and ceramic fibers bound together by pyrolytic material securing said thread-defining element to the core.
