Quicker manufacture meets longer life
Polyurethane composite materials in plant construction
The wind energy capacity installed worldwide today is more than 70 times higher than it was 20 years ago. Nevertheless, the full potential of the unique resource that is wind is far from being exhausted. To come closer to achieving this goal, wind turbines will in future have to convince not only environmentally but also economically. Covestro has developed a special polyurethane resin for this purpose, which is used in conjunction with glass fiber fabrics to create new composite materials. They open up new opportunities for manufacturers and plant operators in terms of efficiency and promote the further expansion of wind energy.
For example: Compared to conventional epoxy resins, infusion resin systems made of polyurethane have improved flow and curing properties. This shortens the production cycles of wind rotor blades and results in lower investment costs for plant owners - a decisive prerequisite for long-term decreases in energy prices, from which society as a whole will benefit. Another advantage is that in addition to faster production, the polyurethane components are characterized by very low fatigue. This ensures smooth operation over the long term.
