Assessment of Ranking of Aluminum-Coconut Shell Ash Composites Using EDAS Method

Abstract

To overcome the difficulty in manufacturing through tools and materials, the present situation calls for the creation of engineering materials to address numerous specific difficulties. Due to attainable qualities that are notable for the components involved, "Metal Matrix Composites (MMCs)" are profitable. Research significance: AMCs are used because of their low density in comparison to aluminium alloys and their interfacial behavior. Due to their outstanding castability and significant erosion protection, AMCs have been effectively repressed in modern automotive production for the “fabrication of various segments, including cylinders, motor lids, connecting shafts, and independent casts”. Research method: The complexity in the evaluation of material assemblage is well-suited to the "multi-criteria decision-making (MCDM)" methodologies. This study ranks "aluminium-coconut shell ash (CSA) composites" using the "EDAS technique", a comparatively fresh and mathematically sophisticated "MCDM (Multi-Criteria Decision Making)" tool. Result: The result obtained by using the EDAS method shows that the rank for 1100 aluminium alloy is fifth, aluminium composite with 5% is fourth, aluminium composite with 10% is second, aluminium composite with 15% is first and aluminium composite with 20% is third.Conclusion: The article's findings indicate that among all materials taken in this research, "aluminium composite with 15% CSA" emerged as the best, followed by "aluminium composite with 10% CSA", whilst the base matrix was discovered to be the material that worked the worst in this investigation.
