This invention discloses a high-temp polymer matrix compound material sliding bearing which is processed according to conventional formation method with the compound material made of high-temp polymer matrix resin with functional additives, reinforced fiber and agent. The said matrix resin is made by teflon mixed with and/or polyamide and modified and the said function additives are nm or mm level mineral nonmetal fillers in which, at least one kind is particle of nm level. This invention provides a low friction ratio, good wearness, long working time, high PV, value, self lubricating compound material sliding bearing. |
