Abstract:
Provided is a friction material that includes a boron-containing solid lubricant. The friction material may be used to form a brake pad for automotive vehicles. The friction material may include, by weight, about 1.0% to about 6.0% of the boron-containing solid lubricant, about 5.0% to about 15.0% of a fibrous or powdered metal material, an abrasive, an organic filler, an inorganic filler, and a binder. Advantageously, an antimony free and copper free friction material of the present disclosure may still achieve high friction performance and long pad life, providing a more environment friendly solution to brake systems.
