The world’s first 64.2m full polyurethane wind turbine blade
With the rapid development of the wind power industry comes the need for larger wind turbine blades, many of which are used in vast offshore energy farms. The increasing size of wind blades has resulted in higher requirements for various aspects of wind turbine manufacturing, including the infusion resin from which they are made. To meet this challenge, we partnered with the Chinese wind turbine giant Goldwind and the wind blade manufacturer LZ Blades to develop the world’s very first 64.2m wind turbine blade made entirely of polyurethane resin – demonstrating the material’s suitability as a cost-effective solution for wind turbines in future.
“Polyurethane is a very cost-effective material, and can thus provide great support for wind power enterprises when wind power prices reach parity with thermal power after 2020.”
“We believe Covestro’s solution can greatly contribute to the sustainable development of the wind power industry.”
“We believe Covestro’s solution can greatly contribute to the sustainable development of the wind power industry,” said Dr. Irene Li, Head of Application Development Asia Pacific, Polyurethanes Segment at Covestro.
“The improvement of blade production efficiency by using polyurethane not only enhances the blade cost competitiveness, but also becomes the key to serve our esteemed customers with material technology flexibility. This keeps us ahead in increasingly challenging market environment. ”
Key benefits of polyurethane resin for wind turbine production
- Long blades Polyurethane resin makes it possible to produce blades with a length of 64.2m from spar cap to the shear web and the shell
- Cost efficient production Compared to traditional epoxy resin, polyurethane infusion resin has better mechanical properties, as well as shorter curing time and faster infusion speed.
- Low temperature performance and resistance Polyurethane infusion resin improves blade performance in lower temperature conditions
