Composite slide bearing

A composite slide bearing comprising:

• a substrate made of a sintered metal;
• and
• a resin layer fixedly superposed on the substrate;
• wherein the resin layer is an injection-molded resin layer comprising a resin composition comprising an aromatic polyetherketone resin and a fibrous filler dispersed in the aromatic polyetherketone resin and is finished to a required resin thickness by machining after injection molding,
• wherein the fibrous filler comprises fibers which are oriented such that a length direction of each of the fibers intersects a rotational direction of the bearing at an angle of 80 to 90 degrees, and
• wherein the resin layer has a thickness of 0.1 to 0.7 mm.

• wherein the resin layer has a thickness of 0.1 to 0.7 mm,
• wherein the resin layer has a thickness which is one-eighth to a half of a thickness of the substrate in a radial direction of the bearing,
• wherein the fibers forming the fibrous filler have an average length of 0.02 to 0.2 mm,
• wherein the resin composition has a melt viscosity of 50 to 200 Pa·s at a resin temperature of 380° C. and at a shear rate of 1000 s−1, and
• wherein the resin composition comprises 5 to 30% by volume of carbon fiber and 1 to 30% by volume of Tetrafluoroethylene, the balance being an aromatic polyetherketone.
