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.
