Fabrication and Tensile Impact and Hardness Test of Al6061/SiC/Coconut Shell Ash Composites

A research study was made to examine the mechanical properties of metal matrix composite which consisting of Al alloy reinforced with Coconut Shell Ash (CSA) and SiC. The experiment involved three distinct mix ratios of CSA and SiC as follows: Sample A (Al6061 96%, SiC 2%, CSA 2%), Sample B (Al60601 92%, SiC 4%, CSA 4%), and Sample C (Al6061 88%, SiC 6%, CSA 6%). Al/SiC/CSE Composites were fabricated by the Stir casting method. For examining the mechanical properties of the composites, Tensile, Charpy, and Hardness tests were conducted as per ASTM D638, ASTM E23, and ASTM E10 Standards respectively. The results revealed that ultimate tensile strength increased due to CSA addition, but hardness decreased. However, there was only a marginal improvement in the percentage of elongation, and the stiffness decreased as well. The experimental study concluded that tensile properties were increased while increasing the amount of Sic and CSA with aluminum also CSA had a favorable impact on the mechanical properties 6061 of hybrid composites.
