This　paper　analyzes　the　nonlinear　dynamic　behaviors　of　the　graphene-reinforced　aluminum-based　aero-engine　blade　under　the　primary　resonance　using　the　amplitude-frequency　response　curves,　bifurcation　diagram,　Lyapunov　exponent　and　Poincare　＇　map.　The　lateral　aerodynamic　load,　longitudinal　aerodynamic　load,　centrifugal　force　and　temperature　are　investigated　for　the　graphene-reinforced　aluminum-based　aero-engine　blade.　Three　kinds　of　configurations　for　the　functionally　graphene-reinforced　gradient　are　considered.　The　effective　Young＇s　modulus　of　the　composite　material　is　given　by　Halpin-Tsai　mode.　The　rule　of　the　mixture　gives　other　material　properties.　The　results　demonstrate　that　the　bifurcation　diagrams　of　the　modal　amplitude　for　the　blade　with　the　lateral　aerodynamic　load,　longitudinal　aerodynamic　load　and　temperature　have　the　periodic-chaos　dynamic　evolution　process　under　the　disturbance　of　the　engine　rotation　speed.　When　the　disturbance　amplitude　reaches　a　specific　value,　a　new　round　of　the　periodic-chaos　dynamic　evolution　will　be　continued.　The　results　also　clearly　indicate　that　the　aero-engine　blade　has　the　rich　and　complex　nonlinear　dynamic　behaviors　which　include　the　hyperchaos,　chaos,　almost　periodic,　typical　period-doubling　bifurcation　and　anti-period-doubling　bifurcation　vibrations.　This　research　is　more　helpful　for　the　engineers　to　understand　the　nonlinear　dynamic　behavior　of　the　blade.
