摘要:
A copper-flee friction material composition for brake pads consists of: 0.43 parts of aramid fiber, 1.9 parts of tire powder, 6 parts of heavy magnesia, 2.55 parts of calcined petroleum coke, 8 parts of ceramic fiber, 6.5 parts of phenolic resin, 14 parts of aluminum silicate fiber, 22 parts of potassium hexatitanate crystal whisker, 25 parts of barite powder, 5 parts of granular graphite, 2 parts of antimony sulfide, 2.8 parts of friction powder of cashew nut oil, 0.9 part of boron nitride, 5 parts of flake aluminum powder, and 0.6 parts of tantalum carbide. Trials show that it has satisfactory high temperature and thermal decay resistant performance, long service life, good abrasion resistance and stable friction coefficient. With the friction material of the present invention used, the brake pad of vehicles is sensitive and stable during braking, produces no screech, is comfortable and has no damage on coupling plate.
