Tycor W fiber reinforced composite sandwich core products have have earned a Certificate of Approval by Germanischer Lloyd (GL) for use in the manufacture of composite wind turbine blades. GL is an international design certification agency for the wind industry. In addition, the certification includes the design and manufacture of products at WebCore’s Miamisburg, Ohio manufacturing facility.
The manufacturer’s ability to offer Tycor W in standard grades gives designers and manufacturers the flexibility to optimize blade designs and have the option to use the material throughout the blade. The composite core material combines fiber reinforcements, such as E-glass roving or mat, with closed-cell, low density foam in an engineered architecture. Tycor W enables improved performance and quality while significantly reducing cost and weight. The product has been in use for over two years in utility-class wind turbine blades. The GL certificate of approval qualifies Tycor W for use with additional 1.5 to 3.0-MW turbines that have blade lengths in the 40 to 60-m range.
