ABSTRACT:
Disclosed are heat-transmitting, anti-friction composites useful for example to reduce sliding friction between the stationary platens and moving belts of continuous hot presses used in the manufacture of consolidated board-like products such as fiberboard. In the disclosed embodiment, the composite comprises a brass sheet perforated in such a manner as to form a multiplicity of rigid prongs projecting transversely from one of its faces. An overlay sheet comprised of polytetrafluoroethylene or other solid lubricant is impaled on the prongs and adhesively bonded to the face of the brass sheet from which the prongs project. The prongs serve to inhibit the tendency of the overlay sheet to undergo plastic flow when subjected to stresses such as are caused by a belt sliding over it. The prongs also serve as paths for efficiently conducting heat through the overlay sheet.
