Al6061 with hard particle reinforcement contains higher stiffness, maximum strength and wear resistance when compare to unreinforced alloy. They can be usage for self-propelled automotive components and aircraft construction. Metal matrix composite (MMC) concentrate chiefly on amended specific strength and wear resistance application. Aluminium as base material and coconut shell ash(CSA) as reinforcement has good potential. The principle difficult is to create this composite in a practical manner. In this project Al6061-CSAp castings with different volume fraction of CSA were produced in an argon atmosphere by an enhanced stir casting method. We found that with more % of CSA addition there is an improvement in specific strength of the composite. Pin on disc equipment used for dry sliding wear analysis of MMCs. The Taguchi analysis revealed the improved specific strength as well as wear resistance. EDS analyses showed oxide phases presence in the castings. Surface Morphology particle distribution were examined in detail by SEM.

Aluminum matrix composites (AMCs) have been extensively studied primarily due to higher strength-to-weight ratio, lower cost, and higher wear resistance properties. However, increasing demand for economical and energy-efficient materials in the automotive, aerospace and other applications is tailoring research area in the agro-based composite materials. Therefore, the aim of this systematic review work is to study the influence of agro-based reinforcements on the tribological and mechanical properties of AMC's processed by various techniques. It was observed that the processing conditions can be designed to obtain uniform structures and better properties AMCs. The agro-waste reinforcement materials, such as rice husk ash, bamboo stem ash, coconut and shell ash can result in a reduction in the density of AMC's without compromising mechanical properties. Moreover, the efficient utilization of the agro-waste leads to a decrease in manufacturing cost and prevents environmental pollution, hence, can be considered as a sustainable material. The state-of-the-art revealed that the agro-based reinforcements do not form brittle composites, as in the case of ceramic reinforced composites. Hence, the study concludes that the agrobased AMCs have great potential to act as a replacement for costly and environmentally hazardous ceramic reinforced-AMCs which can especially be used in various automotive applications that demand higher strength-to-weight ratio, lower cost, and higher wear resistance.

A systematic and efficient approach for the selection of material is necessary to choose a best alternative for the structure or component under consideration. The multi-criteria decision making (MCDM) approaches are well suited to deal intricacy in judgment of material assortment. In this paper, integrated MCDM approaches like analytical hierarchy process (AHP)–technique for order preference by the resemblance to an ideal solution (TOPSIS) and AHP–multi-objective optimization on the basis of ratio analysis (MOORA) methods are used to rank aluminum-coconut shell ash (CSA) composites. The weightage for each criterion is calculated by AHP method and utilized in the TOPSIS and MOORA approaches to rank the materials. The target-based attributes such as density (physical property), hardness, tensile strength, toughness (mechanical properties), wear rate, and coefficient of friction (tribological properties) of the prepared composites are considered in the selection of criteria process. The composites are fabricated using stir-casting process by varying the volume fraction (5, 10, 15, and 20%) of CSA incorporated with Al-1100 matrix. A detailed study on the MCDM approaches revealed that Al-15% CSA composite emerged as the best material followed by Al-10% CSA composite among all, whereas the base matrix is found as the poor performed material in this study.
