Design and static analysis of polymer composite wind turbine blade

Abstract

Wind power is one of the world's fastest-growing energy sector and relatively mature technologies. Wind power is changing the wind energy into electricity, in which the blade plays a very important role. At present large-scale wind turbine blades are almost made of composite materials. Composite materials are a kind of new materials. Because of its high strength, stiffness, weight-lightness, resistance to fatigue, vibration, high temperature, easy-to-design, etc, the composite laminates plates have been widely used in the wind energy field. Therefore, blade vibration analysis, structural design technology and composite materials technology are closely linked. This is a paper on static analysis of polymer composite material for wind turbine blade. By an analysis using CATIA a better wind turbine profile is to be obtained with increased efficiency of energy generation and reduced damage due to vibration.
