LIGNIN-BASED FRICTION MATERIAL

摘要

This invention provides for a friction material composition suitable for friction element formulation. The composition comprises an essentially sulfurfree lignin with low water solubility. The lignin replaces from about 1 to about 30 % on a weight basis with the phenolic resin in the friction material composition. A method of reducing noise within the range of human hearing resulting from friction element performance is also provided.
