St. Louis-based Zoltek Companies Inc. has formed an expanded long-term supply agreement with wind turbine manufacturer Vestas Wind Systems AS, of Denmark. Under the agreement, Zoltek remains the preferred supplier of carbon fibers to Vestas. Zoltek says it expects to provide Vestas with more than $300 million in carbon fiber and carbon fiber materials over the first five years of the agreement for the manufacture of wind turbine blades.
‘This new agreement reflects continued confidence in the expanded use of carbon – both in terms of performance benefits and supply availability,’ says Tim McCarthy, vice president of sales and marketing for Zoltek. ‘Larger, lighter and stiffer rotor blades produced from carbon fiber are the key enabling factor in allowing other turbine components and structures to be lightened and designed more optimally in an integrated fashion.’
