This research presents results of structural designs and evaluations for 3MW Wind Turbine Blade byFEM analysis. After the GFRP model was designed as a baseline model, failure check by Puck’s failure criterionand buckling analysis were accomplished to verify safety of wind turbine blade in the critical designload case. Moreover, applicability of two kinds of carbon spar cap model, was studied by comparing totalmass, price and tip deflection to the GFRP model. The results showed that the GFRP model had sufficientstructural integrity in the critical design load case, and the carbon spar cap model could be a reasonable solutionto reduce weights, tip deflections.
