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.
Cobra International is celebrating its 40th year and has commissioned a book that will look at 40 key projects and 40 key people that were integral to the company’s growth. ‘Klaus Simmer and The King Cobra: A breakthrough in surfboard design and production technology’ is an extract article from this book and a breakthrough composites product for Cobra, establishing its presence as a manufacturer of high performance windsurf boards and creating global visibility for the Cobra brand.
ZSK will hold its bi-annual technology showcase on 21-22 September 2018 at its Krefeld, Germany, headquarters. The Embroidery Technology Show assembles more than 25 exhibitors from around the world to discuss emerging trends in the embroidery manufacturing industry and demonstrate the latest products produced using techniques such as tailored fibre placement (TFP) or smart textiles.
SGL Carbon and Fraunhofer IGCV have officially opened the Fibre Placement Centre (FPC) at SGL's site in Meitingen, Germany. Compositence, BA Composites and the Chair for Carbon Composites at the Technical University of Munich have also joined the alliance, and Coriolis Group and Cevotec are planning to come on board as partners.
