英文摘要：

The blade is a key component of the wind turbine. The wind turbine blade materials will directly affect the performance of the wind turbine. In the present paper,a new carbon fiber composite blade was studied,through finite element analysis of frame beam type blade,the mechanical function and deformation under the load has been investigated. The ply angle of each layer has also been studied. These may provide technical and theoretical basis for improving chinese independent design and manufacturing capacity of long-lived large wind turbine blades.
