Method for fabrication of a profile for a spar cap for a wind turbine blade, spar cap and wind turbine blade

A method for fabrication of a profile for a spar cap for a wind turbine blade, the method comprising:

• fabricating the profile in a pultruding process using one or more strands and/or layers of unidirectional fibres or rovings of unidirectional fibres arranged along a longitudinal direction of the profile;
• and
• moulding the fibres with a tool for moulding fibres, wherein one or more additional fibres or rovings of additional fibres are introduced in the pultruding process prior to the moulding;
• wherein the additional fibres are arranged at an angle to the unidirectional fibres by deflecting the additional fibres in a direction perpendicular to the longitudinal direction of the profile using one or more deflection members that are moved across the longitudinal direction of the profile, before being fed into the tool,
• wherein one or more surficial fibres or rovings of surficial fibres are introduced in the pultruding process after the moulding;
• wherein the surficial fibres are arranged on the outer surface of the moulded profile.
