Abstract: A multi-layer fiber reinforced thermoplastic panel is fabricated using a first fiber reinforced thermoplastic sheet having thermoplastic with a first melting point, a second fiber reinforced thermoplastic sheet having thermoplastic with a second melting point, and a connecting layer therebetween. The connecting layer is made of a thermoplastic-compatible material having a third melting point which is less than the first melting point and second melting point. The connecting layer is bonded to the thermoplastic in the first sheet and the second sheet. The subject invention is also directed to a method of fabricating such a panel.

Abstract: A trailer coupling for use with tractors having a fifth wheel includes a coupling plate having an upper portion for securement to the trailer, a lower portion and a transitional portion extending from the upper portion to the lower portion. An antifriction member is secured adjacent to the lower surface of the lower portion. Openings are provided in the lower portion and antifriction member for passage of a downwardly projecting kingpin therethrough. Support members secure support edge portions of the antifriction member in securing the antifriction member adjacent to the coupling plate. The antifriction member is preferably composed of an ultra high molecular weight polyethylene. The use of through fasteners and the like in securing the antifriction member to the coupling plate is avoided.
