Owens Corning receives GL approval for Ultrablade LT fabrics

Owens Corning's Ultrablade LT fabrics have been granted global approval for wind blade manufacturing by Germanischer Lloyd (GL).

Owens Corning (Toledo, Ohio, USA) announced on Aug. 9 that it has received global approval from Germanischer Lloyd (GL) for its Ultrablade LT fabrics based on its patent pending high-modulus R-glass reinforcements for wind blade applications.

“This approval recognizes the high quality of our Ultrablade LT unidirectional fabrics made of high-modulus R-glass, as well as the stable quality of our worldwide manufacturing processes for this range. This has been confirmed by customer tests as well,” says Sunil Saxena, global director - renewable energy. Seven Owens Corning production sites in six countries have been audited and the certificate extends to all of them.

Saxena adds that “Owens Corning Ultrablade range of products has shown improved mechanical properties in wind applications. They allow transition to longer, lighter and stiffer wind turbine blades, compared to standard E-glass fabrics in epoxy resin.”

Owens Corning already has global Germanisher Lloyd approval for its global fabrics based on its Advantex glass fiber.
