ABSTRACT:
Friction material pads for use in a brake system with an aluminum-metal matrix composite rotor wherein a brake application can create operational temperatures that approach 450C. The formulation of the composition for the friction pads is generically a basic non-asbestos organic formula modified to include a high abrasive content, solid lubricant package, and a porous copper powder. The porous copper powder which makes up from 2-18 percent by weight the friction pads has a nominal diameter of 0.20 mm. The porous copper powder proportionally responds to temperature and mechanical forces generated during a brake application by deforming and smearing to aid in the formation of a glaze between the engaging surfaces of the friction pads and aluminum-metal matrix composite rotor. This glaze prevents scoring of the aluminum-based rotor while at the same time maintaining a substantial stable coefficient of friction of approximately 0.4 during brake applications over a wide range of speeds and deceleration rates.
