A method to produce a pre-impregnated fibrous material, in particular in ribbon form, including a fibrous reinforcement and thermoplastic polymer matrix, including a step of impregnating the fibrous material in the form of a single roving or several parallel rovings with the polymer in the molten state, the polymer in the molten state at the time of the impregnation containing a neutral gas in the supercritical state used as production aid by reducing viscosity in the molten state, preferably the gas being supercritical CO2. |
