Abstract

The invention discloses a fiber reinforced resin matrix self-lubricating compound sliding bearing and a manufacturing method thereof. The fiber reinforced resin matrix self-lubricating compound sliding bearing comprises an inner layer and a back lining, wherein the inner layer is a self-lubricating polytetrafluoroethylene (PTFE) soft band form by mixing self-lubricating polytetrafluoroethylene (PTFE) resin powder with at least one of graphite, molybdenum disulfide, tin bronze powder, glass fiber and carbon fiber; the back lining is formed by dipping and winding alkali-free long glass fiber and epoxy resin glue solution; and the epoxy resin glue solution is prepared by evenly mixing epoxy resin, curing agent, curing accelerator, filler and organic accessory ingredient. The sliding bearing prepared by the method of the invention has the advantages of good self-lubricating property, corrosion resistance, shock absorption, noise reduction, xenembole damage resistance, low cost and the like and is suitable to use at normal temperature.

Description

technical field [0001] The invention relates to a fiber-reinforced resin-based self-lubricating composite sliding bearing and a manufacturing method thereof, in particular to a fiber-reinforced resin-based self-lubricating composite sliding bearing with a polymer self-lubricating material as an inner lining and a fiber-reinforced epoxy resin as a backing Sliding bearing and manufacturing method thereof. technical background [0002] In recent years, with the large consumption of non-ferrous metals and the increase in the cost of non-ferrous metals, the technology of replacing metal materials with organic polymer materials as structural and functional components has achieved rapid development. The Chinese invention patent application with publication number CN1451891 discloses a carbon fiber high temperature resistant self-lubricating bearing. A fixed groove is opened on the inner wall of the base body, and a carbon fiber composite material layer is attached to the inner wall...
