Abstract: A method for manufacturing a wind turbine blade, comprising the steps of:
providing one or more individual pultrusions including a first tapering end with a tapering end face terminating in a taper tip, and
arranging the one or more pultrusions in one layer or more stacked layers including at least a bottom layer on a first assembly surface at a first assembly station to provide a pultrusion arrangement extending in a longitudinal direction between a pultrusion root end and a pultrusion tip end, wherein the first tapering end of the one or more pultrusions form the pultrusion root end or the pultrusion tip end of the pultrusion arrangement.

Abstract: A flow-enhancing fabric extends in a longitudinal direction and in a transverse direction. The fabric includes a plurality of fibre layers including a first fibre layer and a second fibre layer arranged upon each other, the first fibre layer has a first plurality of fibre bundles oriented in parallel in a first fibre direction and has a plurality of first glass fibre bundles and a number of first carbon fibre bundles. The second fibre layer has a second plurality of fibre bundles oriented in parallel in a second fibre direction different from the first direction and has a plurality of second glass fibre bundles and a number of second carbon fibre bundles. At least a number of first carbon fibre bundles intersect and contact a number of second carbon fibre bundles. The fabric has a plurality of monofilaments arranged between the first and second fibre layer along the transverse direction.

Abstract: The present invention relates to an interlayer sheet for a spar cap comprising: a first fibre layer comprising a first plurality of fibres, having a first upper fibre surface and a first lower fibre surface, a second fibre layer comprising a second plurality of fibres, having a second upper fibre surface and a second lower fibre surface. The first fibre layer is arranged on top of the second fibre layer, such that the first lower fibre surface is in contact with the second upper fibre surface. The first fibre layer is of a different characteristic than the second fibre layer. Furthermore, the present invention relates to a spar cap for a wind turbine blade, comprising a plurality of pre-cured fibre-reinforced elements including at least a first pre-cured fibre-reinforced element and a second pre-cured fibre-reinforced element; and a number of interlayer sheets arranged between the plurality of pre-cured fibre-reinforced elements.
