Owens Corning, a supplier of reinforcement materials to the wind energy market, recently launched a new weblog, a shared online journal for designers, engineers and other technical professionals who work with composite materials in wind energy (http://windbladetechnology.owenscorningblog.com). The blog, written and maintained by a team of six Owens Corning executives and engineers, is being used to publicise a breakthrough single-end roving and knitted fabric for wind turbine blades, trademarked WindStrand. Owens Corning says it provides up to a 33% increase in tensile strength over similar materials and between a 25% and 50% increase in fatigue strength. Preliminary studies and field testing indicate that WindStrand will reduce blade weight by as much as 10%. WindStrand was launched a year ago.
