A non-crimp fabric includes at least two superimposed layers made from multifilament reinforcing yarns arranged parallel to each other, and at least one layer made from a non-woven made from thermoplastic polymer material on and/or between the layers made from multifilament reinforcing yarns, wherein the non-woven includes a first polymer component and a second polymer component whose melting temperatures lie below the melting or decomposition temperature of the reinforcing yarns. The first polymer component has a lower melting temperature than the second polymer component, and the first polymer component is soluble in epoxy matrix resins, cyanate ester matrix resins, benzoxazine matrix resins, or mixtures thereof. The second polymer component is not soluble in epoxy matrix resins, cyanate ester matrix resins, benzoxazine matrix resins, or mixtures thereof. A preform is made from the non-crimp fabric. |
