<p>A pre-impregnated material (1) comprises a resin matrix reinforced with a fibre material. The matrix comprises a semi-crystalline layer (10) based on semi-crystalline thermoplastic resin having a melting point T<SUB>f</SUB>, on at least one side of which there is an amorphous surface layer (22, 23) based on amorphous thermoplastic resin having a glass transition temperature T<SUB>g</SUB>, in which the glass transition temperature T<SUB>g</SUB> of the amorphous thermoplastic resin is below the melting point Tf of the semi-crystalline thermoplastic resin.</p> |
