Multiaxial non-crimp fabrics having polymer non-wovens

A non-crimp fabric comprising:

• 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 comprises a first thermoplastic polymer component and a second thermoplastic polymer component whose melting temperatures are below a melting or decomposition temperature of the reinforcing yarns,
• the melting temperature of the first thermoplastic polymer component is lower than the melting temperature of the second thermoplastic polymer component,
• the first thermoplastic polymer component is soluble in epoxy matrix resins, cyanate ester matrix resins, benzoxazine matrix resins, or mixtures thereof,
• the second thermoplastic polymer component is not soluble in epoxy matrix resins, cyanate ester matrix resins, benzoxazine matrix resins, or mixtures thereof, and
• the non-woven contains the first thermoplastic polymer component in a proportion from 2 to 40 wt % and the second thermoplastic polymer component in a proportion from 60 to 98 wt %.
