    摘要: A threaded fastener is made of a composite material made of layers extending parallel to the fastener axis and having elongated filament fibers. A portion of the fibers extend parallel to the axis of the fastener to provide tensile and shear strength to the fastener, and a portion of the fibers extend parallel to the load-bearing thread faces to enhance tensile strength to the threads.

    摘要: A composite fastener which provides up to 70 KSI in shear strength in a 1/4 inch shank diameter and includes several layers having long parallel carbon fibers embedded in resin. The layers are pressed together and heated to form a panel. The panel is cut into bars which are then machined into rods, used to form threaded or unthreaded composite shear pins. The fibers in adjacent layers are angled with respect to one another to provide maximum shear strength in a particular direction. The head of the shear pin is preferably marked to indicate the orientation of maximum shear strength.
