Abstract: There is a dire need for sustainable technologies to be used in the industry and friction stir processing (FSP) is very eco-friendly in that regard. Moreover, the use of natural fibres' ash has been steadily increasing in the industry. In this work, we have explored three different composites viz. Al reinforced with SiC (2%wt), Al reinforced with aloe vera (2%wt), and Aluminium matrix reinforced with both SiC and aloe vera in the same ratio. FSP is applied for the production of surface composites by incorporation of reinforcement in the matrix. The results showed that hardness value is increased with rotational speed and better distribution of reinforcement, which enhance the hardness of the composites. It is observed that rotation speed is the most significant parameter. We used the Taguchi method for optimisation of hardness, with reinforcement and tool rotational speed as variable parameters. The optimised sample was found to be at 1,000 rpm with SiC reinforcement.
