Research on mechanical behavior of AMMC (Al-SiC) composite in disc brake

Abstract

To meet the materials demand and performance of automobile components it is necessary of developing composite materials. Aluminium Metal Matrix Composite (AMMC) are utilized to meet the industrial needs. AMMC is the mixture of aluminium and silicon carbide with minimum quantity of other materials like magnesium, aluminium oxide, graphite which are mixed in precise quantity to increase the chemical, mechanical and thermal properties of material. This paper deals with the investigation of mechanical behaviour and properties of AMMC produced by stir casting technique where silicon carbide is reinforced with alloy 6061 for using in Disc Brake. The tensile, flexural, hardness and impact tests were performed and the results showed that the hybrid composites had better properties than pure aluminium and this kind of material may be subjected to use in Disc Brake. The microstructure of the hybrid composites were analyzed using Optical Microscopy.
