| 摘要 |
The present invention provides a friction material that is used in friction members such as disc brake pads and drum brake shoes of braking equipment for vehicles, does not contain copper or copper-containing metals, improves abrasion resistance during high-temperature braking, and improves noise resistance and the effectiveness of brakes in a wide range of models. Further provided is friction material composition: containing a fiber base material, a friction modifier and a binder; having a copper content of not more than 0.5 mass%; and containing partially graphitized coke and muscovite. The friction material is obtained by molding the friction material composition. |
