Abstract

Method for fabrication of a profile (5) for a spar cap (4) for a wind turbine blade (2), wherein the profile (5) is fabricated in a pultruding process using one or more strands and/or layers of unidirectional fibres or rovings of unidirectional fibres (6) arranged along a longitudinal direction of the profile (5) and a tool (7) for moulding of the fibres (6), wherein one or more additional fibres (8) or rovings of additional fibres are introduced in the pultruding process prior to the moulding, wherein the additional fibres (8) are arranged under an angle to the unidirectional fibres (6), and/or wherein one or more surficial fibres (14) or rovings of surficial fibres are introduced in the pultruding process after the moulding, wherein the surficial fibres (14) are arranged on the outer surface of the moulded profile (5).
