    Abstract: The present invention relates to a method of manufacturing a fibre-reinforced spar cap (45) for a wind turbine blade. A plurality of pultruded fibre plates (70) is arranged in a spar cap mould (62) to form a stacked arrangement (69) of pultruded fibre plates (70). An insert member (86) is arranged next to a lateral surface (67) of the stacked arrangement (69), wherein the first insert member (86) comprises a connecting surface (87), and wherein the first insert member (86) is arranged such that its connecting surface abuts against the first lateral surface (67) of the stacked arrangement (69). Resin is infused into the stacked arrangement (69) and the insert member (86) to form the fibre-reinforced spar cap (45) or a preform thereof, which can be trimmed to the required size.

    Abstract: A method of manufacturing a wind turbine blade shell component (38) is provided, the method comprising arranging a plurality of pultrusion plates (64) on a blade shell material (89) in a mould (77) for the blade shell component. The pultrusion plates (64) are bonded with the blade shell material to form the blade shell component, wherein each pultrusion plate (64) is formed of a pultrusion fibre material comprising a glass fibre material (70) and a carbon fibre material (68), wherein carbon fibre material is provided along the entire lateral surfaces (83, 84) of the pultrusion plate. The glass fibre material is selected from a glass fibre fabric, a glass fibre preform comprising a consolidated arrangement of glass fibres and a binding agent, and a plurality of glass fibres encapsulated by a veil or a foil.
