  • Publication number: 20200223102
    Abstract: A method of manufacturing an impregnated fibrous material including a fibrous material made of continuous fibers and at least one thermoplastic polymer matrix, the method including pre-impregnating the fibrous material while it is in the form of a roving or several parallel rovings with the thermoplastic material and heating the thermoplastic matrix for melting, or maintaining in the molten state, the thermoplastic polymer after pre-impregnation, the at least one heating step being carried out by means of at least one heat-conducting spreading part (E) and at least one heating system, with the exception of a heated calendar, the roving or the rovings being in contact with part or all of the surface of the at least one spreading part (E) and partially or wholly passing over the surface of the at least one spreading part (E) at the level of the heating system.

  • Publication number: 20200216627
    Abstract: The present invention relates to an impregnated fibrous material comprising a fibrous material made of continuous fibers and at least one reactive thermoplastic prepolymer, and optionally a chain extender, characterized in that the at least one reactive thermoplastic prepolymer is partially polymerized, optionally with the chain extender, and has a number-average molecular weight (Mn) ranging from 500 to 10,000, preferably from 4,000 to 8000, the proportion of fibers in the impregnated fibrous material being 45 to 65% by volume, preferably 50 to 60% by volume, and in particular 54 to 60%.

  • Publication number: 20200130234
    Abstract: The invention relates to a process for manufacturing an impregnated fibrous material comprising continuous fibers and a thermoplastic matrix, said fibrous material is made from at least one unidirectional tape and said process comprises a step of pre-impregnating said fibrous material that is in the form of at least one roving with said matrix and a step of heating the matrix after pre-impregnation, said heating step being carried out by means of a non-heated and non-heat-conducting tension device and a heating system, with the exception of a heated calendar, said roving being in contact with the surface of said tension device and running over the surface of said tension device level with the heating system.

  • Publication number: 20190084252
    Abstract: The invention relates to a process for manufacturing a preimpregnated fibrous material containing a fibrous material made of continuous fibers and at least one thermoplastic polymer matrix, wherein the preimpregnated fibrous material is produced as a single unidirectional tape or of a plurality of parallel unidirectional tapes and wherein the process includes a step of impregnating, in particular fully and homogeneously, the fibrous material that is in the form of a roving or of several parallel rovings with the at least one thermoplastic polymer matrix that is in powder form, the impregnating step being carried out by a dry route in a tank and the control of the amount of the at least one thermoplastic polymer matrix in said fibrous material being achieved by control of the residence time of said fibrous material in the powder, with the exclusion of any electrostatic process with intentional charging.
