Owens Corning (Toledo, Ohio, USA) has introduced Ultrablade fabric solutions to help enable the transition to longer, lighter and stiffer wind turbine rotor blades. The company says the new Ultrablade solutions, which will be commercially available in January 2011, can help designers remove nearly a metric ton of reinforcement and resin from 2-MW wind turbine blades compared to same-size blade sets made with traditional E-glass. Ultrablade fabrics in epoxy resin reportedly can reduce spar weight up to 18 percent, increase blade length up to 6 percent, improve blade stiffness up to 20 percent, decrease blade thickness up to 6 percent and increase aerodynamic efficiency and generate higher torque for driving turbines. Total blade weight can be reduced by up to 5 percent. Ultrablade fabric will be produced in a number of the company's facilities globally.
