Abstract :

Aluminum metal matrix composites (AMC) are good candidates for friction material application in vehicle industry. Understanding the mechanism of material behavior under braking loads utilizes perceiving the advantages of fabricating brake pads from AMC material. Pressure, contacting temperature, and sliding velocity are the three critical factors that affect friction and wear performances of vehicles? brake material. A portion of the worn material forms a thin solid film known as tribo-layer or tribofilm with different chemical composition structure and tribological behavior than the material of the sliding contact surfaces over each other. Another part of the worn material may be redistributed, crushed, and consolidated in the sliding interface. A portion of the brake dust (brake wear debris) may be airborne and some other portion may be deposited on the brake hardware. The abrupt formation of three-body abrasion causes significant increment in the applied pressure which affects the wearing mechanism. Incorporation of hard ceramic reinforcement and soft lubricant into AMC increases wear resistance property of frictional material. I also discuss other main parameters affecting the wear mechanism of the brake pad and the reinforced AMC producing methods.
