Composites are beneficial and present in most of the environmental friendly and sustainable way of producing and storing energy. The growth rates are high for renewables market and composites utilized to a developing offshore wind market and larger wind turbines with longer blades. The GE 1.5 megaWatt wind turbine consists of three 116 ft. fiberglass blades and a blade assembly which weighs 36 tons. The use of lighter weight FRP materials means that the turbines can produce more power per unit volume, minimising impact on the landscape. Components must exhibit excellent fatigue strength, resist random loading and corrosion, require minimal maintenance and serve for 30+ years.
