Nonmetal friction material for vehicle disc brake and preparation method and application thereof

The invention relates to the technical field of friction materials, and discloses a nonmetal friction material for a vehicle disc brake and a preparation method and application thereof. The friction material comprises the following components in percentage by mass: 7-10% of binding agent, 15-25% of mineral fiber, 6-10% of inorganic fiber, 1.5-5% of organic fiber, 6-15% of calcium whisker, 12-20% of filler, 3-5% of friction powder, 6-8% of vermiculite powder, 15-26% of carbon friction reducing material, 6-15% of metal sulfide, 2-5% of tire powder, and 1-4% of molybdenum sulfide. The invention further discloses a preparation method of the friction material; and according to the method, the friction material is prepared through weighing, mixing, forming treatment and heat treatment process after formation. The friction material with higher friction coefficient, lower wear rate and excellent heat fade performance is prepared as a brake pad with high brake torque, comfortable emergent brake, short brake distance and lower heat fade.
