The purpose of this study is to supply an analysis tool for Buckling Analysis and Modal Analysis on hybrid blade for large wind turbine by using Finite Element Analysis. Equivalent Property Method, in which a single ply is assumed according to Classical Lamination Theory, and Stacking Property Method, in which the stacking order and the thickness are considered, was applied to conduct Finite Element Analysis. In addition, glass-epoxy and carbon-epoxy, the two materials applied to the shear web and the spar cap to make blades lighter, were used to compare the analysis results. Therefore, it is regarded efficient that rather than inconvenient employing Equivalent Property Method to find out equivalent properties every time, it would be better to use Stacking Property Method because the input is intuitive and various values including various stresses according to different stacking are available. As for Buckling Analysis, Stacking Property Method was employed based on the result of Modal Analysis and Fluid-structure Interaction Analysis was used. Both carbon-epoxy and glass-epoxy showed enough safety factors of the first modal values.
