ABSTRACT:
A low-friction composite structure according to the present invention comprises: (1) a core material with a uniform cross section and having dimensional stability, the core material having two substantially planar surfaces; and (2) at least one polymer layer adhesively attached to one of the substantially planar faces of the core material, the polymer layer having applied thereto a friction-reducing ingredient selected from the group consisting of silicone resins and silicone oils. Preferably, the low-friction composite structure is constructed in segments, with the segments being assembled by groove-and-spline assembly to form the structure, such as through splines. Various additives, such as anti-oxidants, titanium dioxide, thermic stabilizers, ultraviolet stabilizers, hydrophobic ingredients, release agents, and anti-static ingredients, can be added to the polymer layer. Preferably, the polymer is polyethylene.
