摘要： The present disclosure relates to a method for manufacturing a blade segment for a segmented wind turbine blade, and a resulting segment for a segmented wind turbine blade as well as the segmented wind turbine blade. In particular, the blade segment comprises a female spar part defining an inner cavity and having a longitudinal inner end and an opposite longitudinal open end towards an end face of the blade segment, a first spar cap connected to an inner surface of a first shell portion and comprising a first primary spar cap portion. The blade segment further comprises a first secondary spar cap portion affixed to a first outer surface of the female spar part. The first secondary spar cap portion is glued to the inner surface of the first shell portion and/or to the first primary spar cap portion forming a glue interface between the first secondary spar cap portion and the inner surface of the first shell portion and/or the first primary spar cap portion.
