The present disclosure relates to a spar cap () for a wind turbine blade () comprising: a plurality of spar cap layers () and a first interlayer () arranged between the first spar cap layer () and the second spar cap layer () and comprising: a number of first interlayer areas (), including a first primary interlayer area (), comprising a first number of interlayer sheets () comprising a first plurality of fibres (); and a number of second interlayer areas (), including a second primary interlayer area (), comprising a second number of interlayer sheets () comprising a second plurality of fibres (), wherein the first number of interlayer sheets () is of a different characteristic than the second number of interlayer sheets ().

Optimized spar cap structure for wind turbine blade

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.

Method for manufacturing a wind turbine blade and wind turbine blade obtained thereby

The present disclosure relates to an interlayer for being arranged between a first element and a second element of a fibre reinforced composite material, the interlayer comprises an interlayer sheet comprising one or more fibre layers extending in a fibre layer plane, the one or more fibre layers including a first fibre layer comprising a first plurality of fibres and having a first upper fibre surface and a first lower fibre surface, wherein the interlayer sheet has an upper interlayer surface and a lower interlayer surface and wherein the interlayer comprises a plurality of conductive fibres, wherein each of the plurality of conductive fibres forms part of the upper interlayer surface as well as the lower interlayer surface.

Interlayer, a spar cap and a wind turbine blade

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.
