Abstract
Versatile properties of aluminium make it the most common metal used now a days and it is used in various sectors like automobile, aerospace, civil etc. When mixed with other materials, properties like high tensile strength with high strength to weight ratio, high wear resistance low density and low coefficient of thermal expansion can be obtained. Aluminium with SiC, B4c, etc. forms a wear resistance hybrid. Its application is mostly in the brake drum of the automobile sector. Brake shoe of the brake drum is manufactured of cast iron so therefore a detailed study is done on both the properties of cast iron as well as the Al/SIC/Al2O3 composite. These hybrids are also used in sectors like construction to construct light weight racks, claps etc. The Composition of the manufactured composite is varied and tested to get the best fit for brake drum. Various tests performed are tensile test, tribology test and scanning-electron microscope to analyse properties of hybrid composite. Performance of the manufacture composite is evaluated on the basis of wear test as wear resistance is the most effective property that a brake shoe should possess. The method used here for manufacturing the composite is stir casting.
