Abstract: 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.

Abstract: The present invention relates to a method of manufacturing a fibre-reinforced spar cap (45) for a wind turbine blade. A plurality of pultruded fibre plates (70) is arranged in a spar cap mould (62) to form a stacked arrangement (69) of pultruded fibre plates (70). An insert member (86) is arranged next to a lateral surface (67) of the stacked arrangement (69), wherein the first insert member (86) comprises a connecting surface (87), and wherein the first insert member (86) is arranged such that its connecting surface abuts against the first lateral surface (67) of the stacked arrangement (69). Resin is infused into the stacked arrangement (69) and the insert member (86) to form the fibre-reinforced spar cap (45) or a preform thereof, which can be trimmed to the required size.

Abstract: A precured fibrous composite strip for a load-carrying structure for a wind turbine blade has a first longitudinal end and a second longitudinal end, a first side and a second side with a width defined as the distance between the first side and the second side, and an upper surface and a lower surface with a thickness defined as the distance between the upper surface and the lower surface. The strip includes a taper region with a taper length at the first longitudinal end. The taper region tapers in thickness towards the first longitudinal end. The taper region includes a first taper section proximal to the first longitudinal end and having a first average taper angle, a third taper section distal to the first longitudinal end and having a third average taper angle, and a second taper section between the first taper section and the third taper section.
