Abstract
One of the main global engineering challenges for wind energy sector is to develop efficient wind turbines with high fatigue life. Large wind turbine blades are made out of polymer composites to give high specific stiffness and strength, and good fatigue performance. However, large composite structures are prone to defects such as delamination and adhesive failure, which can lead to crack initiation and propagation under cyclic stresses. The presented study covers an overview on manufacturing defects of wind turbine blades, in-service damages and available inspection techniques, which are used to identify defects in wind turbine blades. In this paper, the detection capabilities and performance of visual inspection, acoustic emission, ultrasonic testing and X-try inspection have been reviewed. As concluded remarks, the paper describes the importance of developing quality control guidelines for wind turbine manufacturing sectors based on standard inspection methods.
