  • Method of preparing a low-friction laminate liner for bearings
    Patent number: 4006051
    Abstract: A laminate liner adapted to be secured to a supporting surface, which liner comprises in combination: a backing sheet member characterized by a number of relatively large openings therein; a fibrous polymeric sheet material characterized by a number of small openings therein, the fibers composed of a thermoplastic polymeric material having low-friction, self-lubricating properties; and a hardenable resin binder material, the hardenable resin binder material impregnated into the openings of the backing member, and the fibrous polymeric sheet material compressed into the openings of the backing member to form an integral, unitary, laminate liner, the liner characterized by having a low-friction facing surface composed of the polymeric sheet material compressed and bonded to the backing member, and a resin-rich backing surface, the backing surface adapted to be secured by heat pressure to a supporting surface to form a bearing liner.
