Glass fiber reinforced polyamide resin composition with excellent wear resistance

摘要

PURPOSE: Provided is a glass fiber reinforced polyamide resin composition, which has excellent wear resistance suitable to be used for materials of a bearing cage, an automobile door check arm and the like. CONSTITUTION: The glass fiber reinforced polyamide resin composition comprises 100 parts by weight of a polyamide resin, 0.5 to 5 parts by weight of an ultra-high molecular weight polymethylsiloxane, and 5 to 15 parts by weight of a polytetrafluoroethylene. In particular, the polyamide resin is polyamide 6 or polyamide 66. Further, the composition satisfies the wear resistance criteria that the dynamic frictional coefficient is 0.01 or less and the specific wearing amount is 10 mg or less.
