A collaborative research project between the American firms Sandia National Laboratories and the Wind Blade Division of Knight & Caever (K&C) has allowed to design an innovative wind turbine blade specially developed for low-wind regions. The new blade, namely STAR™, is made of glass fiber reinforced epoxy resin. It has 27.5 meter long and a special curved shape in order to withstand to gusty turbulent wind. In fact such a composite wind turbine blade is lightweight and exhibits high corrosion resistance as well as high tensile strength.
