The first polyurethane fan turbine blade in Asia was successfully manufactured

Covestro successfully manufactured Asia’s first polyurethane wind turbine blade . Designed for wind turbines up to 1.5 megawatts, the 37.5-meter-long blade uses Covestro’s unique infused polyurethane and fiberglass cloth from Chongqing International Composite Materials (CPIC), a leading domestic fiberglass manufacturer, produced in Shanghai. FRP Research Institute completed. The blade is manufactured using a vacuum infusion system developed by process technology provider HüBERS and equipped with a continuous degassing unit.

Kim Klausen, Global Head of “Wind Energy Projects” at Covestro, is very satisfied with this new milestone: “We have once again demonstrated that polyurethane has a significant performance and cost advantage over epoxy resins in wind power generation. Advantage.” Polyurethane has excellent physical properties and flow properties, and can fully saturate glass fibers. In addition, polyurethanes release less heat during processing than epoxies.

Polyurethane material makes wind power more efficient

Kim Klausen said: “A faster curing of the resin can significantly increase productivity. This can bring clear cost advantages to manufacturers.” Covestro’s Danish Wind Power Center and Covestro’s Research and Development Center (PRDC) in this In the project, we will work closely together to carry out resin research and development.

Recently, Dr. Zhang Chenxi, a researcher of Covestro, introduced this latest achievement at the 2016 China International Wind Power Composite Materials Summit held in Zhejiang. He explained the advantages of the polyurethane system to more than 500 wind energy experts on site, and introduced the cooperation process between Covestro and glass fiber suppliers, process partners and rotor blade manufacturers.

Join hands with wind energy companies

At the summit forum, Dr. Roland Stoer, general manager of Windnovation, the world’s leading blade design company, expressed his views on polyurethane materials: “We hope to optimize the design of rotor blades and make full use of the advantages of polyurethane. Thanks to Xtron’s research strength and perseverance, we are willing to cooperate with Covestro to design more sophisticated rotor blades in the future.

In the latest Chinese government work report, Premier Li Keqiang called for a further increase in the use of clean energy. The move could spur further expansion of the domestic wind power system. In 2016 alone, domestic wind power capacity is expected to add more than 30 GW.
