Description

technical field [0001] The invention relates to the field of friction materials, in particular to a friction material with good running-in performance. Background technique [0002] Friction materials are usually composed of five types of materials: binders, reinforcing fibers, abrasives, lubricating materials and fillers. Its functions are as follows: [0003] Binder: Bonds powder materials such as reinforcing fibers, abrasives, lubricating materials and fillers together. Modified phenolic resins are generally used. Commonly used are: cashew nut shell oil modified phenolic resin, nitrile rubber modified phenolic resin, aromatic hydrocarbon modified phenolic resin and various imported high temperature resins. [0004] Reinforcing fiber: plays a key role in the friction process of friction materials, can play a reinforcing role and improve friction and wear performance characteristics. Commonly used reinforcing fibers are: asbestos fiber, steel fiber, copper fiber, vermic...
