Application of Pultrusion Technology in Wind Turbine Blades

 

The pultrusion process is widely used in the wind power field due to the Vestas beam cap forming technology. The pultrusion process maximizes the axial mechanical properties of the fiber, combines and bonds multiple unidirectional plates into a curved beam, and then forms a rigid beam through the upper and lower beam caps and webs. It is indeed a cost-effective and reliable technical route that can be carried forward.

 

Domestic wind power pultrusion originated from the promotion of embedded bolt technology in 2013; the pultrusion process is used to produce UD blocks and embedded bolt sleeves. The product quality is stable and the price is favorable.

 

 

Fiber content is precisely controlled, with high straightness, and high fiber content improves performance by 20%. Blade assembly production is realized, beam mold is eliminated, and the main mold occupation time is shortened. Automated continuous production is suitable for mass production with stable quality. From yarn to finished product, the production process is simplified and costs are reduced.
