Abstract A calcium sulfate crystal whiskers reinforced asbestos-free friction disk of car is prepared from iron ore, barite, vermiculite, graphite, carbon black, rubber powder, calcium sulfate crystal whiskers, steel fibres and resin through modifying surface, proportional mixing, and hot die pressing at 200-320 deg.C. Its advantages are less pollution, low cost, stable physical and chemical properties and friction coefficient, high antiwear and heat resistance, higher mechanical strength, no toxicity and low noise.
