Abstract
Disclosed is a thin-wall bonded self-lubricating plate, the composite material structure thereof being composed of a surface self-lubricating layer, an intermediate bonding layer, and a metal backing layer. The surface self-lubricating layer includes polytetrafluoroethylene, ultrahigh molecular weight polyethylene, etc. The surface self-lubricating layer thereof is thicker than an ordinary sintered self-lubricating material, thereby reducing vibration and prolonging the service life. Components, such as bushings, gaskets, sliding plates, composite bearings and other special-shaped members, made of the thin-wall bonded self-lubricating plate, have broad application prospects in low-speed rotation and relative sliding parts of vehicles, general machinery, office furniture, etc.
