Abstract

A tape-like dry fibrous reinforcement, the ‘Gapped UD reinforcement tape’, providing channels or flow-paths created by inclusion of a layer of separated fiber tows held by at least one adhesive layer. Hereby, quicker wetting of fibers with matrix is obtained, whereby improved composite materials can be economically produced. A method and apparatus for producing the Gapped UD tapes are also disclosed.
