The present invention relates to an impregnated fibrous material comprising continuous fibers and at least one reactive thermoplastic prepolymer, and optionally a chain extender, wherein the at least one reactive thermoplastic prepolymer is optionally partially polymerized with the chain extender. And a number average molecular weight (Mn) in the range of 500 to 10,000, preferably 4,000 to 8,000, wherein the proportion of fibers in the impregnated fiber material is 45 to 65% by volume, preferably 50 to 60% by volume, in particular 54 to 60% by volume. To impregnated fibrous material, characterized in that%. |
