Abstract
Disclosed is a self-lubricating composite material prepared from polymers, used for the fabrication of bearing members. The composite material is characterized by the fillers or solid lubricants contained therein which have been treated with titanates or silane compounds and by the liquid lubricant contained therein which include polar compounds. Bearing members made by this self-lubricating composite material have a lower friction coefficient than commercial self-lubricating bearing members, can use thermoset plastics as a matrix and can be made into colored products.
