The　nonlinear　and　chaotic　vibrations　of　the　rotating　functionally　graded　graphene　platelet　reinforced　composite　(FG-GPLRC)　pre-twisted　blade　subjected　to　the　aerodynamic　force　are　investigated　by　taking　into　account　the　cantilever　boundary　condition.　The　rotating　FG-GPLRC　pre-twisted　blade　is　simplified　to　a　rotating　FG-GPLRC　pre-twisted　cylindrical　panel.　The　graphene　platelets　(GPLs)　are　dispersed　uniformly　and　oriented　randomly　in　every　layer　while　the　GPL　volume　fractions　vary　from　the　layer　to　layer,　which　leads　to　four　different　GPL　distribution　patterns.　Based　on　the　strain-displacement　relationship　of　the　pre-twisted　cylindrical　panel　derived　by　Green　strain　tensor,　the　natural　frequencies　of　the　rotating　FG-GPLRC　pre-twisted　cylindrical　panel　are　obtained　by　using　the　first-order　shear　deformation　theory　and　Chebyshev-Ritz　method.　Lagrange＇s　formulation　is　used　to　derive　the　nonlinear　ordinary　differential　equations　of　motion.　The　complex　chaotic　vibrations　of　the　rotating　FG-GPLRC　pre-twisted　cylindrical　panel　are　investigated　by　performing　numerical　simulations　on　the　basis　of　Runge-Kutta　algorithm.　The　bifurcation　diagrams,　Lyapunov　exponents,　time　histories,　phase　portraits　and　Poincare　maps　are　depicted　to　detect　the　periodic　and　chaotic　vibrations　of　the　rotating　FG-GPLRC　pre　-twisted　cylindrical　panel　with　different　parameters,　such　as　Coriolis　force,　GPL　distribution　pattern,　steady-state　rotating　speed,　perturbation　rotating　speed　and　aerodynamic　force.　The　double-parameter　maximum　Lyapunov　exponent　is　regarded　as　an　effective　method　to　detect　the　chaotic　regions　of　the　rotating　FG-GPLRC　pre-twisted　cylindrical　panel.
