This article deals with the effective attributes of friction material application out of aluminum matrix
composites (AMC) containing disperse ceramic phase, particularly SiC particles, via literature survey and result analyzing
of the relevant research works. These properties include thermal expansion coefficient, wear, friction coefficient,
mechanical and thermal strength, durability, etc. The wear mechanism of braking in brake pads is discussed to perceive
the material behavior of the friction pad constituents and phases to ameliorate the vehicle’s brake pad performance
considering its main tasks. The discussion elaborates the advantages and the disadvantages of AMC as friction material
based on the essential brake pad properties defined by automotive standards parameters and the vehicle industries
requirements. Analysis of the results presented in this paper suggests that the optimized reinforced AMC may result in a
new patent for friction material applied in the vehicle brake pad.
Keywords: Brake pad, cermet, aluminum matrix composite, SiC particles, wear mechanism, wear rate.
