In　this　paper,　the　nonlinear　vibration　response　of　a　new　three-phase　composite　cylindrical　shell　made　of　epoxy　resin,　graphene　nanoplatelets　and　carbon　fiber　is　studied.　Based　on　the　first-order　shear　deformation　theory　and　the　von-Karman　geometric　nonlinear　relation,　the　nonlinear　partial　differential　equations　of　motion　of　a　new　three-phase　composite　cylindrical　shell　are　established　by　Hamilton　principle,　taking　into　account　the　interaction　of　hygrothermal,　aerodynamic　force　and　external　excitation.　The　Galerkin’s　method　is　combined　with　the　pseudo　arc-length　continuation　solution　to　address　the　internal　resonance　problem　of　nonlinear　systems.　In　this　paper,　the　impact　of　moisture　difference　and　external　surface　excitation　on　the　nonlinear　forced　vibration　response　of　a　new　three-phase　composite　cylindrical　shell　is　studied　©　The　Author(s),　under　exclusive　license　to　Springer　Nature　Singapore　Pte　Ltd.　2024.
