| 摘要 |
The present invention provides a friction material having reduced noise after being left in cold conditions when used as a disc brake pad, brake lining, or the like, and copper components are essentially not included in the friction material. The present invention is: a friction material composition including a fiber base material, a binding material, and a friction adjusting material, the copper content of the friction material composition being no more than 0.5% by mass, and the friction material composition containing fluorine-based polymer particles; and a friction material obtained by molding the friction material composition. |
