PURPOSE:To provide a resin composition for sliding member, containing a heat-resistant thermoplastic resin, polytetrafluoroethylene resin powder, high- strength pitch-base carbon fiber and carbon beads and usable without damaging a contacting soft material such as soft metal. CONSTITUTION:The objective resin composition for sliding member contains (A) 55-70wt.% of (A1) a polyarylene sulfide containing >=50wt.% of the recurring unit of formula I and/or (A2) a polyarylene thioether ketone containing >=50wt.% of the recurring unit of formula II (Co and S are bonded to para-positions), (B) 5-20wt.% (preferably 10-15wt.%) of polytetrafluoroethylene resin powder, (C) 10-30wt.% (preferably 15-25wt.%) of pitch-base carbon fiber having a tensile strength of >=150kgf/mm<2> (preferably >=200kgf/mm<2>) and (C) 5-15wt.% of carbon beads having an average particle diameter of 10-100mum and preferably having a carbonaceous texture. |
