Technical Field

The application belongs to the wind power field, and particularly relates to a wind energy blade.

Background

The design of blades in a wind driven generator directly influences the conversion efficiency of wind energy and the annual energy production of the wind driven generator, and is an important ring for wind energy utilization. The blades are the most basic and key components in the wind driven generator, and the good design, reliable quality and superior performance of the blades are the determining factors for ensuring the normal and stable operation of the unit. The severe environment and long-term continuous operation have higher and higher requirements on the blades along with the development of the wind power generation industry. Stiffness is also a very important indicator for the blade. Research shows that the rigidity of the Carbon Fiber (CF) composite material blade is two to three times of that of the glass fiber reinforced plastic composite blade. Although the performance of the carbon fiber composite material is greatly superior to that of the glass fiber composite material, the price is high, and the application of the carbon fiber composite material in the wind power generation in a large range is influenced.
