Method, prefabricated structural element and mold for making a wind turbine member

A method for making a wind turbine member comprising the steps of:

• arranging a plurality of components of the wind turbine member in a mold having an inner side configured to determine a surface of the wind turbine member and the mold having a positioning receptacle disposed on the inner side thereof, at least one of the components being a prefabricated structural element having a fixed geometry with an outer surface;
• said prefabricated structural element forming an integral part of the wind turbine member;
• said prefabricated structural element having a positioning projection protruding out of the outer surface thereof so as to define an undercut with respect thereto;
• inserting the positioning projection into the positioning receptacle so as to permit said positioning receptacle to fill said undercut in a form tight manner to predetermine the disposition of the prefabricated structural element in the mold and to prevent relative movement between said prefabricated structural element and said mold in at least two spatial directions;
• and,
• interconnecting the components of the wind turbine member disposed in the mold.
