Effect of Different Weight Percentage on Mechanical Properties of Aluminum Metal Matrix Composites through Hybrid Reinforcement - A Review

In last few years due to industrialization and advancement of latest technology, the demand for lightweight, high performance, eco-friendly and energy efficient material in the field of construction, aerospace and automotive has increased because conventional materials were fail to achieve desired combination of mechanical and physical properties due to their heavy weight, high processing cost and insufficient mechanical properties. To overcome this and to fulfill the latest demand for today’s materials, aluminum metal matrix composites (AMMC,s) is one of the best alternatives for researcher in various engineering fields like transportation, structural, mechanical, nuclear and aeronautics due to its excellent properties like low density, adequate strength, large coefficient of linear expansion, superior castability, good corrosion resistance and easily alloyed with other elements. Among various fabrication methods, stir route of casting is adopted for the manufacturing of AMMC,s as it is simple, flexible & cost-effective. The aim of present work is to study aluminum hybrid metal matrix composite(AHMMC,s) through different combination of hybrid reinforcements such as two different ceramics, two different wastes and one ceramic and one waste and see the effect of different weight percentage on the mechanical properties like hardness, toughness, compressive & tensile strength.
