Abstract: An interlayer sheet for a spar cap is provided. The interlayer sheet includes a first fibre layer having a first plurality of fibres with a first upper fibre surface and a first lower fibre surface, and a second fibre layer having comprising a second plurality of fibres with 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. A number of the interlayer sheets may be arranged between a plurality of pre-cured fibre-reinforced elements to make a spar cap for a wind turbine blade.

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.
