The present invention relates to a method for manufacturing a turbine blade for a wind turbine . The invention also relates to a turbine blade for a wind turbine .
In common production processes of turbine blades for wind turbines , a plurality of turbine blade parts is manufactured in separate production steps and merged together to form the turbine blade by a bonding process .
The turbine blade parts are usually manufactured in a molding process . In such molding processes , reinforcement material , such as fibers or the like , and resin are arranged in a mold and subj ected to a curing process , usually under the provision of heat .
Subsequently, the turbine blade parts are demolded and aligned to form the turbine blade . In the aligned state , the turbine blade parts are bonded together by an adhesive . The adhesive is arranged at bonding lines between the turbine blade parts , especially in mutual contact zones .
Due to manufacturing tolerances of the turbine blade parts , such as an unwanted variation of a thickness of the turbine blade parts in the mutual contact zones , a thickness of the adhesive often varies along the bonding lines . This means that gaps between the turbine blade parts are filled with the adhesive . Moreover, since extra adhesive has to be provided to fully close all gaps , surplus adhesive may flow out of the gap and cure along the bonding line at an inner wall or outer wall of the turbine blade . Especially at the outer wall of the turbine blade , this requires an extra production step to remove the superfluous adhesive . It is therefore the obj ect of the present invention to eliminate or at least partially eliminate the disadvantages described above in the case of a manufacturing process for a turbine blade . In particular, it is the obj ect of the present invention to create a turbine blade for a wind turbine and a method for manufacturing a turbine blade for a wind turbine that avoids cumbersome adhesive removal processes in a simple and inexpensive manner .
