    摘要: A method of manufacturing a friction article wherein a fiber material (14) having a continuous and substantially uniform three dimensional matrix which is filled with a slurry (24) made up of fillers, friction modifiers, a reinforcing material and a liquid binder. The filled fiber material is conveyed to a dryer (32) where the volatile solution is evaporated leaving the fillers, friction modifiers, reinforcing material and binder. The filled fiber material (14) is thereafter placed in an oven (50) where a compressive force is applied thereto while the binder is cured to define a second matrix which holds the fillers, friction modifiers, and reinforcing material in the three dimensional matrix.

    摘要: 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.

    摘要: A noise sensor for supplying a central processing unit of an anti-lock brake system with a noise signal corresponding to vibrations produced during braking. The central processing unit responds to the noise signal by supplying a control valve assembly with an operational signal which modulates the fluid pressure supplied to a wheel cylinder to create a predetermined fluid pressure frequency therein to nullify vibrations and correspondingly attenuate noise produced thereby.
