Abstract

A formed article of fiber-reinforced thermoplastic resin which has been adapted for use in a sliding member by restoring the wear resistance once degraded by the addition of reinforcing fibers to the normal level is disclosed. This formed article comprises a fiber-reinforced resin material of a thermoplastic resin containing reinforcing fibers and incorporating therein additionally as a sliding property-imparting agent a material having a storage elastic modulus in the range of 3.5×10 Pa to 5.0×10 Pa in a service temperature range of 30° C. to 70° C. The ratio of incorporation of the sliding property-imparting agent is properly in the range of 4 to 10% by weight when the matrix resin is a polyamide-based resin or 4 to 20% by weight when the matrix resin is a thermoplastic resin other than the polyamide-based resin, respectively based on the total weight of the resin and the reinforcing fibers.
