<![CDATA[Graphene-reinforced aluminum matrix composites (AMCs) have strong potential as lightweight materials with enhanced mechanical performance. This systematic review examined fabrication methods, optimal compositions, and mechanical improvements in AMCs reinforced with graphene nanoplatelets (GNP), graphene nanosheets (GNS), graphene oxide (GO), and reduced graphene oxide (rGO). The review covered 25 indexed international journal articles published between 2012 and 2024 from Scopus, Google Scholar, and Web of Science, with article selection following the PRISMA framework. The findings show that planetary ball milling, powder metallurgy, sintering, friction-stir-based processing, wet coating, and High Pressure Torsion (HPT) vary in effectiveness in achieving graphene dispersion and interfacial bonding. Hardness increased by up to 43%, tensile strength by 317%, and yield strength by 25% with rGO contents below 1 wt.%. HPT increased hardness from 64 to 122 HV at 0.25 wt.%, while RFSSW improved shear strength by 31% and fracture toughness by 20%. Key research gaps include limited hybrid fabrication studies and the lack of standardized industrial-scale testing parameters.]]>
