The invention relates to a method for the impregnation of continuous fibres, that comprises coating said fibres with a polymer matrix containing at least one thermoplastic semi-crystalline polymer having a glass transition temperature (Tg) lower than or equal to 130 DEG C, and nanotubes of at least one chemical element selected from the elements of the columns IIIa, IVa and Va of the periodic table. The invention also relates to the composite fibres that can be obtained by said method, and to the use thereof.
