Shanghai, China — Covestro’s new wind turbine rotor blade which uses a polyurethane resin in the manufacture has won the JEC Innovation Award at the 22nd China Composite Expo.
Covestro’s head of polyurethane application development, Asia Pacific Irene Li said the “recognition boosts our confidence in the project’s viability.”
As UTECH-polyurethane.com reported in April, Covestro made the 37.5m-long blade using its polyurethane infusion resin and glass fibre mats from Chongqing Polycomp International, a Chinese glass fibre maker at the Shanghai FRP Research Institute.
A vacuum pressure infusion system with continuous degassing was used to produce the rotor blade.
Jenny Geng, marketing director of Covestro Asia Pacific, added: “Product development can hardly be done without listening to needs of market and customers.
“With our solutions, we can contribute toward reducing the overall cost of wind turbine rotor blades. Together with our partners, we will collaborate to produce longer and lighter blades with higher power generation efficiency.”
The China Expo-JEC was held between 31 Aug and 2 Sep 2016.
