Abstract
One of the main global engineering challenges for the wind energy sector is to develop efficient wind turbines with high fatigue life. Large wind turbine blades made out of polymer composites elevate specific stiffness, 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 stress. The presented study covers an overview of the manufacturing defects of wind turbine blades, in-service damages and the available inspection
techniques that are used to identify defects in wind turbine blades. In this paper, the detection capabilities and performance of visual inspection, acoustic emissions, ultrasonic testing and X-ray inspection have been reviewed. The paper describes the importance of developing quality control
guidelines for wind turbine manufacturing sectors based on standard inspection methods.
