Wind energy is gaining ground in the field of renewable energy and is predicted to provide up to 8% of the world's consumption of electricity by 2021. Advances in Wind Turbine Blade Design and Materials reviews the design and functionality of wind turbine rotor blades and the requirements and challenges of composite materials used in current and future blade designs. Part One outlines the challenges and developments in wind turbine blade design, including aerodynamic and aeroelastic design features, fatigue loads, and characteristics of wind turbine blade airfoils. Part Two discusses the fatigue behavior of composite wind turbine blades, including the micromechanical modelling and fatigue life prediction of wind turbine blade composite materials, and the effects of resin and reinforcement variations on the fatigue resistance of wind turbine blades. Part Three describes advances in wind turbine blade materials, development and testing, including biobased composites, surface protection and coatings, structural performance testing and the design, manufacture and testing of small wind turbine blades. Advances in wind turbine blade design and materials offers a comprehensive review of the recent advances and challenges encountered in wind turbine blade materials and design, and will provide an invaluable reference for researchers and innovators in the field of wind energy production, including materials scientists and engineers, wind turbine blade manufacturers and maintenance technicians, scientists, researchers and academics.
