Ranking of Aluminum-Coconut Shell Ash (CSA) Composites using the WASPAS Method

To select the optimum option for the structure or component under consideration, a careful and effective material selection technique is required. The intricacy of the evaluation of material assortment is perfectly suited to the multi-criteria decision making (MCDM) methodologies. Coconut shell ash is a byproduct obtained during the burning of coconut shells. It has gained significant attention due to its potential applications in various industries. Some of the research studies have shown that coconut shell ash can be used as a low-cost adsorbent material for the removal of heavy metals and organic pollutants from wastewater. Overall, the research on coconut shell ash has shown its potential as a valuable resource that can be utilized in various industries, contributing to sustainable development. Depending on the desired qualities and uses, multiple production techniques can be used to create coconut shell ash composites. The methodology used to produce coconut shell ash composites will depend on the desired properties and applications of the final product. The choice of method will also affect the mechanical, thermal, and other properties of the composite. The WASPAS method is for optimizing the Alluminium-Coconut Shell Ash (CSA) Composites. Alternate Parameter: AI-1100, AI-5%CSA, AI-10%CSA, AI-15% CSA, AI-20%CSA. Evaluation parameter: Ultimate tensile strength (N/mm2), Toughness (J/mm3), Density (g/cc) and Wear rate (10-3 mm3 /m) .Al-1100 has a preference score of 0.674158, placing it in the 5th rank. Al-5% CSA has a preference score of 0.746743, ranking it 4th. Al-10% CSA has a preference score of 0.8728, earning it the 3rd rank. Al-15% CSA has the highest preference score of 0.992877, making it the top-ranked composite. Al-20% CSA has a preference score of 0.888162, securing the 2nd rank. Ranking aluminum-coconut shell ash composites is a methodical assessment and comparison of their characteristics and functionality utilising a range of resources and techniques. Researchers and engineers can determine whether these composites are appropriate for a given application by taking into account elements like mechanical strength, thermal stability, corrosion resistance, and cost-effectiveness. They can also optimise the composition of these composites to achieve the needed attributes.
