Friction material composition, friction material, and disc brake pad |
| abstract |
[Object] This invention, on an assumption that the environmental situation must be considered, reduces the brake noise, prevents the reduction of the braking effectiveness in the high temperature range, and improves the wear resistance.[Means to Resolve] In the NAO friction material composition that does not practically contain a copper component, this invention contains the first substance made of such as the calcium carbonate that is the substance which becomes the sintered body during braking and is the precursor of the sintered body which keeps the powder generated from the disc rotor, and the second substance made of such as the fluoropolymer that is the sintering additive which aids sintering of the first substance.[Selected Drawing(s)] None |
