Abstract: A review of the root causes and mechanisms of damage and failure to wind turbine blades is presented in this paper. These massive structures are subjected to harsh environmental conditions, including wind, rain, ice, and extreme temperatures. A proactive wind turbine blade repair strategy is crucial to maintain. . Additionally, blades are the most challenging and expensive components to fix, with a single element replacement costing in the region of approximately $300 000 to $500 000.
