摘要： The present invention relates to a fibre composite material W of increased translucency and/or mechanical strength, comprising a copolymer C encompassing monomers A-1, where A-1 form covalent bonds with functional groups B-1 on the surface of fibres B embedded in the fibre composite material W, and this fibre composite material W has greater translucency and/or mechanical strength than a fibre composite material Win which the copolymer C contains no A-1. The present invention further embraces a method for producing a fibre composite material W of increased translucency and/or mechanical strength.
