The air contain very low density of energy, as a result the complex 3D shape blade is required for maximize the energy extraction. The blades of the wind turbine will suffer the tough nature environment. The complex 3D shape blade with thick composite layers creates unique challenge for the design and structure analysis. The equivalent property of a composite layer that contains multiple plies of laminates is often used in the analysis of the thick composite structures. This study focused on a methodology to calculating the equivalent material properties on the 3D blade with thick composite layers. The research applies reverse engineering method to sample the blade material in order to get the equivalent material properties of complex composite 3D blade. By doing this, an equivalent material properties of composite blade can be used in the finite element analysis. The result can also provide a guide line for stress and fatigue design of blade.
