ABSTRACT:
A composite coupler carrier assembly for railroad cars comprising a lower metallic attachment plate shaped and arranged to be mounted on the car structure supporting the coupler shank, and an upper planar polymeric bearing body of ultra high molecular weight polyethylene that defines an upwardly facing planar bearing surface on which the coupler shank rides. The metallic attachment plate and the polymeric bearing body are fixed to each other by the practice of a spin welding technique involving the forming of a plurality of apertures of frusto-conical edging in the attachment plate, in which the small sides of the apertures are on the same side of the plate, and placing the underside of the polymeric bearing body against said side of the mounting plate, and spin welding in each aperture, to the bearing body, a polymeric disc that is of the same material as the bearing body, and that is proportioned to thereby anchor the attachment plate to the bearing body.
