MARKET INFORMATION : WIND ENERGY DELIVERING THE FUTURE OF COMPOSITE SOLUTIONS WIND ENERGY Over the last 15 years, the material solutions developed by Gurit for manufacturers of wind turbine blades have continuously contributed to the increasing efficiency of wind power installations. This progress is most visible when looking at the increase of a typical blade size from 23 metres to over 80 metres plus. The growing dimensions create enormous challenges for wind turbine blade manufacturers as the longest blades today weigh in excess of 20 tons each. New materials solutions were needed to keep the weight of the blades as light as possible, yet maximising their strength, stiffness and durability. Gurit has helped make wind energy a technical and also a commercial success story by helping to decrease manufacturing costs of wind turbine blades and enhancing the efficiency of wind power installations With over 15 years' experience, Gurit has developed a broad range of award-winning products and solutions and is unique in covering both nfusion and prepreg blade technology, with the capability to supply all the relevant materials needed for building a composite blade The successful creation of a large composite structure needs specialist knowledge of structural design, materials technology and composite processing. Gurit is in the unique position of possessing all of these disciplines in one integrated technology centre, maximising the potential for innovation and rapid development of technology solutions Whatever the blade technology, Gurit has the product and development capability to meet the customers' requirements and expectations.
