ABSTRACT:
A friction material matrix is described, containing a tin oxide, such as but not limited to stannous oxide or stannic oxide, and a binder system, the binder system physically or chemically binding the tin oxide. The tin oxide is preferably present in an amount in the range of about 0.3 to about 20 weight percent, based on the total weight of the friction material matrix. The tin oxide preferably has a Mohs hardness level of about 6.5. The tin oxide improves the performance behavior of a friction couple at an interface between the friction material matrix and an automotive braking element.
