The present invention relates to an organic friction material used as a yaw brake for a wind turbine, characterized in that it comprises a solid lubricant, an abrasive, a fibrous substrate, a binder, a filler and a friction modifier. The brake organic friction material has excellent durability due to the small amount of wear between the counterpart and the brake. It is low noise, environmentally friendly, and has little change in the friction coefficient according to various conditions. Do. |
