Abstract

Method for manufacturing an impregnated fibrous material including a continuous fiber material and a thermoplastic polymer matrix. The material is made from a single unidirectional ribbon or a plurality of unidirectional parallel ribbons. The method includes a step of pre-impregnating a roving of the material with the matrix and a step of melting the matrix. The melting step is carried out by means of a heat-conducting tension device and a heating system, the tension device being thermostatically controlled at a temperature, for a semi-crystalline thermoplastic polymer, from Tc−30° C. to Tm+50° C., and, for an amorphous polymer, from Tg+50° C. to Tg+250° C., the roving running over the surface of the tension device in the heating system, and the porosity rate in the material being less than 10%.
