Abstract
Because of their remarkable mechanical qualities, metal matrix composites (MMCs) based on aluminum are becoming more and more popular in a variety of industries. In this work, we explore the possibility of improving the mechanical and tribological properties of aluminum matrix composites by reinforcing them with coconut shell ash (CSA). CSA is a common agricultural waste product that is produced by burning coconut shells under regulated conditions. Using a stir casting method, different volume fractions of CSA (5%, 10%, 15%, and 20%) are poured into an Al-1100 matrix to create the Al-CSA composites. The link between parameters and mining techniques is taken into consideration by the Weighted Product Model (WPM) techniques. They are renowned for outperforming other methods of decision-making in terms of accuracy and computing speed. The ideal mining technique for a bauxite mine should be determined using these techniques, according to the research. The typical cut and fill method is the most appropriate mining strategy, as demonstrated by a comparison of the results with previous research' methodologies. Following a comprehensive analysis of Multi-Criteria Decision-Making (MCDM) techniques, the Al-15% CSA composite was shown to perform the best, followed by the Al-5% CSA composite. On the other hand, our investigation showed that the basic matrix was the least effective material. Because of its sustainability, CSA is a desirable reinforcement material for aluminum matrix composites, providing a more affordable and environmentally responsible option than standard reinforcements. The study's conclusions offer insightful information about the possible uses of Al-CSA composites in a range of sectors, such as the automotive, aerospace, and marine industries. Subsequent investigations may concentrate on refining the manufacturing procedure and augmenting the mechanical and tribological characteristics of these composite materials for particular uses. All things considered, this study shows that CSA can be used to reinforce aluminum matrix composites, creating new opportunities for the development of sustainable materials.
