The present invention relates to a consolidated composite pre-form for reinforcing a composite structure, said pre-form comprising fibers and a binding agent, said pre-form having a sheet-like structure with an upper major surface and a lower major surface, and said pre-form being provided with recesses on at least a portion of at least one of said major surfaces.
1. A method of producing a pre-form, comprising: providing a layer of a binding agent;providing a fibre layer of fibres or fibre tows on the layer of a binding agent to produce a delimited longitudinal sheet-like pre-form of fibres and a binding agent, the pre-form having an upper major surface and a lower major surface;applying a vacuum to consolidate the pre-form by removing air from the pre-form, and imprinting recesses into at least one of the major surfaces of the pre-form by application of pressure to the at least one of the major surfaces during t...
