  • High strength fiber reinforced polymeric fasteners having threads, for example a nut and bolt
    Patent number: 5152945
    Abstract: In the production of a fastener, reinforcing fibers (20) are wetted out in a bath (22) of thermoset resin, drawn together into a wetted cable (23) which is placed in a `U`-shaped die recess of a first die part (24), having parallel inner side walls (25), a second part (29) of the molding die having side walls (30) and a concave die surface then closes the recess by slidably engaging the parallel inner side walls (25), and pressure is applied to the wetted cable without expulsion of wetted fibers. Both die parts (25, 29) have die surfaces which include contours (31) of fastener surfaces, which may be outstanding threads, or annular buttress type projections radiating from the shank .
