Abstract:
A friction material containing, as a binder, a lignin-phenol resin having a weight average molecular weight of 5,000 or less or a cardanol-modified lignin-phenol resin having a weight average molecular weight of 5,000 or less. The friction material is produced by a method including: reacting a lignin having a weight average molecular weight of 5,000 or less, a phenol, an aldehyde, and optionally a cardanol, in the presence of an acid catalyst.
