Abstract

The invention discloses a friction material composition comprising an enhancing material, a bonding agent, a resin modification agent, a friction adjustment agent and a filling material. The enhancing material comprises glass fiber, yellow paper fiber, grey paper fiber and ceramic fiber. Relative to 1 part by weight of glass fiber, the enhancing material comprises 1-3 parts by weight of the yellow paper fiber, 0.4-1.2 parts by weight of the grey paper fiber and 0.5-2 parts by weight of the ceramic fiber. Relative to 1 part by weight of the enhancing material, the friction material composition comprises 0.3-0.9 parts by weight of the bonding agent, 0.1-0.5 parts by weight of the resin modification agent, 0.2-0.8 parts by weight of the friction adjustment agent, and 0.5-1.5 parts by weight of the filling material. The invention also provides an automobile braking friction material prepared from the friction material composition. With the above technical scheme, the strength and high-temperature friction coefficient stability of the friction material are improved.

Description

technical field [0001] The invention relates to the field of friction materials, in particular to a friction material composition and a friction material for automobile braking. Background technique [0002] Automobile friction material is the key material of automobile brakes, clutches, etc. It is a multi-component composite material with structural and performance requirements. With the development of the automobile industry in various countries, people have higher and higher requirements for the environmental protection and safety of vehicles, which makes the performance requirements of friction materials higher and higher. Among them, the following technical requirements should be met: 1. Sufficient and stable friction 2. Good mechanical strength and physical properties; 3. Good thermal conductivity, wear resistance and anti-adhesion; 4. No noise, environmentally friendly and sustainable. [0003] The friction material for automobile brake is a kind of composite materia...
