Abstract: Method for manufacturing a material including a fibrous material with continuous fibres and a thermoplastic polymer matrix, the material being produced as a unidirectional band, the method including a step of pre-impregnation of a strand of the fibrous material by the matrix in powdered form, the pre-impregnation step being carried out in a fluidised bed including a grooved roller component, the strand being in contact with the surface of the roller component and including up to 0.1% by weight of sizing, the matrix rate being controlled by controlling the dwell time in the powder and by constantly controlling the tension of the strand when it is introduced into the fluidised bed.

Abstract: Impregnation of a fibrous material made from continuous fibres with a thermoplastic polymer matrix, the fibrous material comprising a thermoplastic sizing polymer and, before impregnation, an initial width. The method comprises an expansion step which is carried out by means of at least two tensioning members (E) and a heating system SC for heating the tensioning members and/or the fibrous material, the expansion being from 1.5 to 5 times the initial width. The expanded fibrous material is cooled below the Tg of the thermoplastic sizing polymer by means of a cooling system before being brought into contact with the thermoplastic polymer matrix.
