Ashland Resin Shows Potential Advantages for Wind Turbine Blade Construction

19 February 2010

Research presented at the American Composites Manufacturing Association annual meeting, Feb. 9-11, indicated that epoxy vinyl ester resins, specifically Ashland’s Derakane resin, could potentially deliver advantages over traditional epoxy resins for wind blade construction.

The research was presented by Kevin Lambrych, global wind energy technology leader for Ashland Performance Materials, a commercial unit of Ashland Inc.

According to the studies presented by Lambrych, using epoxy vinyl ester resins could save money and speed up competition time.

“When you compare the economics of epoxy blades to epoxy vinyl ester blades in manufacturing, there is an opportunity for a typical manufacturer to save approximately 25 to 30 percent per blade,” said Lambrych. “Derakane epoxy vinyl ester resin also cures much more quickly than straight epoxy.”

Lambrych’s research also compared dynamic mechanical properties and suggested that epoxy vinyl ester resins fall well within the requirements as established by Germanischer Lloyd, the global organization that has established performance standards for the wind energy industry.

In comparison performance tests carried out during the study, Ashland’s Derakane resin delivered equivalent strength characteristics to epoxy resin and reach its final curing stage in one-third less time.
