Carbon　nanotubes　(CNT)　and　graphene　(Graphene)　have　excellent　mechanical　and　physical　properties　and　are　ideal　reinforcements　in　metal　matrix　composites.　In　this　paper,　ball　milling　process　and　hydrogen　thermal　reduction　method　were　used　to　construct　CNT-RGO　hybrid　reinforcement　on　the　surface　of　aluminum　powder,　and　then　spark　plasma　sintering　system　(SPS)　and　rolling　process　were　used　to　prepare　CNT-RGO/Al　composites.　The　CNT　and　RGO　enhanced　phase　distribution,　interface　microstructure,　grain　morphology　and　mechanical　properties　were　studied　by　EBSD,　SEM,　TEM　and　stretching,　and　the　collaborative　reinforcement　mechanism　of　CNT　and　RGO　in　the　CNT-RGO/Al　composite　was　investigated.　The　results　show　that　the　CNT-RGO/Al　composite　exhibits　excellent　mechanical　properties.　The　yield　strength　and　tensile　strength　are　228　MPa　and　268　MPa,　respectively,　which　are　higher　than　those　of　pure　aluminum.　The　yield　strength　and　tensile　strength　of　CNT-RGO/Al　composite　increase　by　153%　and　143%,　respectively　compared　with　those　of　pure　aluminum,　and　the　elongation　of　CNT-RGO/Al　composite　still　remains　8.5%.　The　addition　of　graphene　in　the　composite　not　only　causes　the　one-dimensional　CNT　and　the　two-dimensional　RGO　to　form　a　bridge　structure,　which　effectively　refines　the　grains,　and　is　beneficial　to　the　transfer　of　load,　but　also　promotes　the　interfacial　reaction　between　C　and　Al,　which　is　beneficial　to　bonding.　C-Al　interface　of　the　material.　The　synergistic　strengthening　effect　of　CNT-RGO　hybrid　reinforcement　is　better　than　that　of　simple　one-dimensional　CNT.　©　2022,　China　Science　Publishing　&　Media　Ltd.　All　right　reserved.
