Abstract: In manufacturing, metal matrix composites (MMCs) are used for many applications due to their lightweight, strong surface, and mechanical properties. Because it has valuable applications in the defence and space fields, its possible low cost and easy to use applications are worth exploring. Aluminium metal matrix composites (AMMCs) are good materials for various applications, due to their good properties both physically and mechanically. When reinforcements are added into the metallic matrix, it enhances the fracture toughness, wear resistance, creep resistance, and fatigue resistance compared to conventional engineering materials. Herein, a comprehensive review is made on the preparation of metallic MMCs by different routes and materials, as well as an overview of the effects of addition on different reinforcements in aluminium alloy, highlighting their advantages and disadvantages. This paper also discusses the agglomerating phenomena, matrix bonding, the problems that result in particle distributions, then suggests a novel method for preparing functionally graded MMCs.
