Flange connection for a wind turbine rotor blade, stiffening position for a flange connection, flange flange, wind turbine rotor blade, wind energy plant and method for producing a flange connection

摘要

The invention relates to a flange connection (128) for a wind turbine rotor blade, which has an outer laminate layer (140) and an inner laminate layer (138). There is provided between the outer and inner laminate layers (138, 140) a stiffening layer (144) having elongated profiles (148) of a dimensionally stable material adjacent to and spaced from each other along the outer laminate layer (140) on the outer laminate layer (140). 140) are arranged. Further, a plurality of female threads (142) are provided which are each surrounded by a further laminate layer (146) and arranged in a receiving area (149) between two elongated profiles (148), so that the further laminate layer (146) of each sleeve (14). 142) is at least partially in contact with the outer laminate layer (140). The invention also relates to a stiffening layer (144, 160), a flange feeder (136), a wind turbine rotor blade (110), a wind energy plant (110) and a method for producing a flange connection (128).
