<div> The size of wind turbine blades has gotten larger over time, in order to achieve the highest efficiency energy conversion possible. At the same time, to increase the penetration and utilization of sustainable wind power, the use of natural and bio-based materials has grown in popularity. All of these issues present challenges in terms of the design, manufacture and operation of wind turbine blades.<BR> <br> This book provides an authoritative overview of developments in wind turbine blade design and materials, covering the fundamental wind turbine blade design challenges and developments and computational modeling approaches to blade design. The opening chapters focus on design challenges and developments, detailing wind turbine blade materials challenges and developments, advanced materials, degradation and defect issues and blade inspection and certification. The second section explores advanced materials and wind turbine blade manufacture, performance testing and operation and maintenance of wind turbine blades.</div>
