Abstract

A pre-form (6) comprising a plurality of layers of fibres, e.g. in the form of fibre tows, each layer of fibres being arranged in a layer of resin is disclosed. The layers of fibres and resin define a thickness which is at least 12 mm. The pre-form can be used as a reinforcing structure, e.g. in the form of a slab (6), in a spar (1) or a blade shell for a wind turbine blade. Due to the large thickness, the pre-form can replace several prior art reinforcing structures, which previously had to be positioned individually in the spar or blade shell in order to provide the required strength. Thereby the number of manufacturing steps required for manufacturing the spar is reduced. Furthermore, the capacity of the manufacturing equipment used for producing the pre-form is utilised to a greater extent. Furthermore, a method for manufacturing such a pre-form is disclosed.
