  • Materials for Wind Turbine Blades: An Overview

    2017-11-8u2002·u2002The Gedser turbine (three blades, 24 m rotor, 200 kW, Figure 1 b) was the first success story of wind energy, running for 11 years without maintenance. In this way, the linkage between the success of wind energy generation technology and the application of composite materials became an issue from the beginning: the first turbine, built with steel blades, failed, while the second one, …
