The primary means of mobility today are vehicles. For better braking system better materials are provided for tribo pairs. To reduce the cost of the tribo pairs instead of metals, composite materials are used recent days. This topic deals with the combination of brake disc and brake pad which is generally called tribo pair. As a consequence of its distinctive qualities like high fatigue strength, high hardness, high strength, high specific modulus, light weight and low density, the use of Al-SiC Metal Matrix Composites for brake disc & pad have been steadily expanding in recent years. The properties of the metal matrix composite like tensile and compression strength, as well as hardness, are investigated in order to identify the optimal carbide percent. For brake pad different material compositions are mixed together and in powder metallurgy method brake pad fabrication is developed. Previously Asbestos is commonly employ as a material for brake pads in automobiles. Brake pads are subjected to a great deal of friction, which generates a great deal of heat. Asbestos is a better heat absorber and dissipater than other materials. The main downside of asbestos is that it is extremely harmful to human's health. That’s why asbestos can be replaced by other materials. This paper mainly covers recent advancement of composite brake friction materials along with comparison of every component with proper validation. |
