<p>A pre-impregnated material includes a resin matrix reinforced with a fiber material. The matrix has a semi-crystalline layer based on semi-crystalline thermoplastic resin having a melting point Tf, on at least one side of which there is an amorphous surface layer based on amorphous thermoplastic resin having a glass transition temperature Tg, in which the glass transition temperature Tg of the amorphous thermoplastic resin is below the melting point Tf of the semi-crystalline thermoplastic resin.</p> |
