A laminated composite bearing material has a bearing portion ply comprising fabric of, for example, glass fibers and interwoven fluorocarbon resin fibers. The fabric is woven in a manner such that the surface to be used as the bearing surface of the resultant molded article has predominantly or substantially PTFE fibers exposed. Additionally, an opposing surface is woven so as to have the other fibers exposed thereon to facilitate bonding to a support body ply. The body ply preferably comprises at least one layer of glass fiber fabric, and is predeterminedly oriented relative to the bearing portion ply or plies for improved strength in the laminated structure. Finally, impregnating the body and the bearing portions, to bond them together, is an adhesive matrix. |
