PURPOSE:The titled resin composition having good frictional characteristics, and excellent heat resitance, abrasion resistance, and moldability, suitable for the manufacture of a friction material, containing specified quantities of a lubricant and cleavable inorganic filler. CONSTITUTION:30-70wt% polyphenylene sulfide resin (e.g. Ryton-PPS-P-4 by Phillips Petroleum Co.), 5-15wt% polytetrafluoroethylene resin (preferably particulate), 1-5wt% molybdenum disulfide (preferably particulate), 10-25wt% cleavable inorganic filler (e.g. talc, mica or graphite, having particle diameters of about 0.1-50mum), and 10-25wt% fibrous reinforcement (e.g. carbon fibers of a length of about 6mm. or potassium titanate fibers) are compounded. |
