Synthesis of Graphene-Reinforced Metal Matrix Composites For Aerospace Applications

Graphene-Reinforced Metal Matrix Composites (GRMMCs) persist in becoming a potential group of materials for use in spacecraft because they have better electrical, thermal, and mechanical qualities. This review is mostly about the methods used to make GRMMCs, such as spark plasma sintering, stir casting, and powder metallurgy. It shows how these methods change the way graphene is spread out, how it bonds to other materials, and how well it stays together in the metal matrix. The review also talks about the important factors that determine how well GRMMCs work, like the amount of graphene they contain, how they are dispersed, and how they combine with other materials. Adding graphene to metal grids improves their qualities like tensile strength, stiffness, resistance to wear, and ability to conduct heat. This makes them perfect for use as structural and functional parts in aircraft settings. The problems that come with clustering, bad wetting, and surface degradation are also discussed, along with ways to fix them. At the end of the study, directions for future research are given to improve the stability as well as the scalability of GRMMCs for aircraft use and make the synthesis processes more efficient.
