Fast advancements in the mechanical industry constantly place a demand for new and dependable materials. Metal matrix composites (MMCs) are one of the most prominent candidates to perform indispensable jobs in the mechanical industry. In particular, carbon nanostructures, e.g., graphene and carbon nanotubes (CNTs) are found as excellent support reinforcement materials in MMCs. This review article focuses on graphene/CNTs reinforcement in aluminium (Al), the third-most abundant metal on earth, for improvement in mechanical properties. The article evaluates the impact of graphene/CNTs reinforcement in the Al matrix based on key parameters, e.g., yield strength, microhardness, ductilityand tensile strength. Moreover, different Al-graphene/ CNTs processing (primary and secondary) methods have been reviewed.
