In order to improve the efficiency of today’s wind turbines, various types of attachment parts are fixed to the rotor blades. These parts are either attached in the final step of the production process or equipped on-site. The preferred method to attach the parts is adhesive bonding as it prevents any damage to the skin of the blade.
