Characterization of Mechanical Properties of Different Agro-derived Reinforcements Reinforced in Aluminium Alloy (AA6061) Matrix Composite: A Review

Abstract

The metal matrix composites (MMCs) are increasing day by day in the entire manufacturing sectors due to their unique properties such as high strength to weight ratio, good mechanical properties, and better durability. The application of waste material in metal matrix composites has been getting more attention as they can reinforce particles in a metal matrix which enhance the strength properties of the composites. In addition, by applying these wastes materials in a useful way not only save the manufacturing cost of products but also reduce the pollution on the environment. Aluminium MMCs have found applications in the manufacturing of various components such as a piston, cylinder block, and brake drum, in which wear and friction are an important phenomenon. A comprehensive literature review is carried out on MMCs based on individual reinforcement and multiple reinforcements including various product applications. It is summarized in form of fields involved in tribology, fabrication processes/parameters, reinforcement(s), matrix contribution, tribological testing parameter, and product application areas of MMCs. This paper attempts to review the different combination of reinforcing material(s), both synthetic and agro-derived used in the processing of hybrid aluminium matrix composites, its effect on different mechanical and wear properties of the composite. Different methods for production of these materials have been studied and discussed in detail. Compatibility of agro-derived reinforcements with AMCs and research areas for further improvement of MMCs has been suggested.
