The blade meets the wind power industry's demand for longer, stronger blades

· All-polyurethane blades help wind power companies reduce costs and increase efficiency

Material manufacturer Covestro announced today that it has successfully developed the world's first 64.
2-meter all-polyurethane resin fan blade with wind turbine manufacturer Goldwind Technology and wind turbine blade manufacturer Zhongfu Lianzhong, realizing the material's application in the field of large-scale wind turbine blades.
A major breakthrough to meet the wind power industry's demand for a new generation of longer, stronger blades

The blade is made of polyurethane resin material from the main beam, web and blade shell, which is the first case in the global wind power industry

"Through the joint R&D cooperation with Goldwind Technology and Zhongfu Lianzhong, the leading enterprises in China's wind power industry, the excellent performance of polyurethane resin has been further verified in this trial production

Help wind power companies reduce costs and increase efficiency

The results of R&D tests show that polyurethane resins can exhibit superior mechanical properties compared to conventional epoxy resins

At the same time, Goldwind can better utilize the advantages of polyurethane in terms of mechanical properties and perfusion efficiency by optimizing the blade structure design, ensuring the smooth production of all-polyurethane resin fan blades

Wen Birong, head of Goldwind's blade development team, said: "Polyurethane is a very cost-effective material and will provide strong support for wind power companies to face the same price policy after 2020.
In the

future, the two parties will Increase investment in the development of new materials, and study how to apply these technologies in large offshore blades to improve the competitiveness of Goldwind blades
.

Jitendra Bijlani, R&D Director of Zhongfu Lianzhong, said: "Using polyurethane resin can improve blade production efficiency

With the rapid development of the wind power industry, the large-scale wind turbine blades have become a trend, which puts forward higher requirements for wind turbine manufacturing, including the requirements for infusion resin materials
