Experimental Investigation on Mechanical and Tribological Properties of Al / Sic / Carbon Fibre Metal Matrix Composite

The preparation and characterization of aluminum 6061 alloy with low-cost reinforcements such as Silicon Carbide and Carbon fibre in different combinations is presented in this study for Automobile brake pad application. The reinforcements Silicon Carbide and Carbon fibre were varied as 2%, 4%, 6%, and 8% by volume and fabricated using Stir casting process. Five samples were fabricated and their mechanical properties, micro structural properties were analyzed and results are obtained. The composite with Al 6061 and reinforcements Silicon Carbide-8%, Carbonfibre-2%, by volume fraction has shown improved mechanical properties like tensile strength, wear resistance and hardness compared to the parent material. The microstructural properties analyzed using Scanning electron Microscope and XRay Diffraction shows good bonding between there inforcements and matrix materials in the composite.
