Researchers now focus on new technologies in the development of automobile components with lightweight properties, good wear resistance, high hardness, and high tensile strength is one of the primary goals of designers and manufacturers. In this study, an Aluminium-Based Composite Material that comprises Coconut Shell Charcoal and Cow Bone Ash as reinforcement was developed. A stir casting method was used in the production of the specimens. The responses considered in this study are hardness, tensile strength, melting temperature, density, wear index, and creep rate. A total of 16 runs were generated by the D-Optimal Design Expert software. With the help of the D-Optimal design expert software, an optimized blend of the matrix and the reinforcement particles was obtained as follows; 81.75% weight of aluminium, 8.36% weight of coconut shell charcoal and 9.90% weight of cow bone ash with a desirability of 95.20%. The developed model in this study predicted the responses with their accuracy for hardness, tensile strength, melting temperature, density, creep rate and wear index as 99.88%, 98.70%, 99.56%, 99.69%, 99.10% and 94.23% respectively.
