Abstract:

One of the key technologies of large-scale wind turbine composite blades developed, it relates to the aerodynamics, structural dynamics, structural testing of composite materials, process manufacturing, mold equipment technology, technical difficulty. The vast majority of the world leaves glass fiber reinforced plastic (FRP) composites manufacturing, the main consideration fiberglass / composite other materials do not have some advantages. Numerical results are presented in this paper to investigate the load pressure effect on the middle and the root of the blade. From the results of finite element analysis, leaves uneven force is very complex. The skin panels withstand normal stress caused by the bending of the left skin consider tensile strength under stress.
