The　new　functionally　grated　graphene　platelets　(FG-GP)　reinforced　rotating　pre-twisted　composite　laminated　blade　may　exhibit　strong　nonlinear　vibrations　under　combined　the　transverse　aerodynamic　force　and　axial　excitation.　These　nonlinear　vibrations　are　major　contributors　to　the　overall　failure　of　the　rotating　pre-twisted　composite　laminated　blade.　In　this　paper,　the　resonant　responses,　threshold　surface,　global　bifurcations　and　double-parameter　multi-pulse　chaotic　dynamics　of　the　rotating　pre-twisted　composite　laminated　blade　are　investigated　on　the　basis　of　the　nonlinear　dynamic　model　of　the　new　FG-GP　reinforced　rotating　pre-twisted　composite　laminated　blade　for　the　first　time.　Considering　the　primary　parametric　and　1:1　internal　resonances,　the　averaged　equations　for　the　new　FG-GP　reinforced　rotating　pre-twisted　composite　laminated　blade　are　derived　by　using　the　multiple　scale　perturbation　(MSP)　method.　The　amplitude-frequency　and　force-amplitude　response　curves　are　obtained　to　analyze　the　resonant　responses　of　the　new　FG-GP　reinforced　rotating　pre-twisted　composite　laminated　blade.　The　extended　Melnikov　method　is　used　to　explore　the　threshold　surface,　global　bifurcations　and　double-parameter　multi-pulse　chaotic　dynamics　of　the　new　FG-GP　reinforced　rotating　pre-twisted　composite　laminated　blade　under　combined　the　transverse　aerodynamic　force　and　axial　excitation.　Through　the　theoretical　analysis　and　numerical　simulation,　it　is　discovered　that　the　new　FG-GP　reinforced　rotating　pre-twisted　composite　laminated　blade　exhibits　the　hard　spring　characteristics.　The　energy　transfers　between　two-order　modes　are　proved　by　the　occurrence　of　the　bubble　response　shape.　The　complex　double-parameter　multi-pulse　chaotic　vibrations　are　investigated　for　the　new　FG-GP　reinforced　rotating　pre-twisted　composite　laminated　blade　under　the　influence　of　different　parameters.　These　results　have　the　significant　theoretical　guidance　for　the　optimized　design　of　the　new　FG-GP　reinforced　rotating　pre-twisted　composite　laminated　blade.　©　2024　Elsevier　Ltd
