ABSTRACT:
A fifth wheel insert, laminate composite and method of construction, which insert includes a cap or cover having mount tabs for tack-welding the insert on a fifth wheel. The laminate composite includes a composite of ultra-high molecular weight polyethylene resin and one or more modulus of elasticity modifier such as carbon fibers and is designed to be secured to the fifth wheel of a tractor, the coupling plate of a trailer or to the insert mounted on the fifth wheel, in order to reduce friction and eliminate the need for greasing the fifth wheel-trailer coupling. In a preferred embodiment the laminate composite is constructed by mixing ultra-high molecular weight polyethylene powder and carbon fibers, applying heat and pressure to the mixture to produce a sheet of composite material having superior cold-flowing, lubricity and modulus of elasticity characteristics, preparing the surface of the fifth wheel, coupling plate or fifth wheel insert to receive the laminate composite, preparing the laminate composite surface to bond with the fifth wheel or insert and cementing the sheet laminate composite to the fifth wheel or the insert.
