ABSTRACT:
A threaded member including a core, a thread-defining element helically extending around and along the core and a reinforcing tubular fabric layer bonded to the exterior surface of the combined core and thread-defining element. The radial projection of the thread-defining element defines a helical thread whose contour is followed by the fabric layer and the exterior surface of the threaded member. The composite threaded member may be formed by forming a braided or knit fabric layer on an elongated spiral wrapped core. The spiral wrapped thread-defining element and the fabric reinforcing layer is bonded to the core. A polymer sheath protects the underlying structure.
