Assessment of Mechanical Properties of Aluminium Metal Matrix Composite Reinforced with Carbonized Eggshell Ash (CESA)

Abstract

A useful alloying agent for aluminium-based composites is eggshell powder, which has a well-deserved reputation for hardness. Aluminium cans and eggshells are regarded as waste and a pollutant because they are no longer needed. Conversion of wastes into useful products will be of economic boost for a nation and make the environment clean. Eggshell particles were studied for their reinforcing properties in a waste aluminium alloy in this study. An eggshell particle of 150 µm in size and a weight fraction of 2%, 4.4%; 6.6%; 8.8%; and 10% was incorporated into aluminium produced from recycled aluminium wastes during casting. A Light Emission Polyvac Spectrometer was used to determine the alloy's constituent makeup. The required experimental procedures and tools were used to measure the tensile strength, hardness, and impact strength. Using a weight fraction of reinforcement of 2, 4, 6, 8, and 10%, tensile strength was found to be 78.07098MPa; 81.09587MPa; 83.04546MPa; 86.12769MPa; and 89.12769MPa respectively. Hardness values of 75.25Hv, 77.03Hv, 78.27Hv, 80.15Hv, and 85.72Hv were obtained at the same specified% weight fraction. Impact strength values of 12.64J, 10.08J, 7.39J, 7.12J, and 7.39J were obtained at the same composition. It may be inferred that the mechanical characteristics of the aluminium alloy reinforced with eggshell particles improved considerably with the number of eggshell particles used and the study, therefore, converted waste to worth.
