摘要： L'invention concerne un procédé de fabrication d'un matériau fibreux pré-imprégné comprenant un matériau en fibres continues et une matrice thermoplastique, où ledit matériau pré-imprégné est réalisé en un un une pluralité de rubans unidirectionnels et où ledit procédé comprend une étape de pré-imprégnation dudit matériau fibreux se présentant sous forme d'une ou plusieurs mèches (81a) par ladite matrice thermoplastique se présentant sous forme de poudre, ladite étape de pré-imprégnation étant effectuée par voie sèche dans une cuve (20) comprenant un lit fluidisé (22) comprenant une pièce d'embarrage lisse (82), et ladite mèche comprenant jusqu'à 2.5% en poids d'ensimage,
ladite mèche (81a) étant en contact avec la surface de ladite pièce d'embarrage lisse (82),
et le contrôle du taux de ladite matrice thermoplastique dans ledit matériau fibreux étant effectué par contrôle du temps de séjour dudit matériau fibreux dans la poudre et par contrôle constant de la tension de ladite mèche (81a) lorsqu'elle pénètre dans le lit fluidisé.-

摘要： An apparatus (1) for applying a liquid matrix to a fibre (20) comprises a belt press (4) arranged to receive and compress the fibre between two moving belts, a matrix application roller arranged to receive and transfer liquid matrix to the fibre, a second matrix application component arranged adjacent to the matrix application roller forming a first gap (6) between the component and the matrix application roller; wherein the matrix application roller is positioned adjacent to the belt press forming a second gap (7) between the matrix application roller and a belt of the belt press; and wherein the second gap is larger than the first gap. Positioning the matrix application roller adjacent to the belt press and controlling the relative size of the gaps controls the amount of liquid matrix material that is applied to the fibre and prevents excess matrix material from being transferred to the belt press.

摘要： A fiber-reinforced resin material having minimal directionality of strength as well as excellent productivity, a method and device for manufacturing a fiber-reinforced resin material whereby a molded article is obtained, and a device (2106) for inspecting a fiber bundle group. A method for manufacturing a sheet-shaped fiber-reinforced resin material in which a paste (P1) is impregnated between cut fiber bundles (CF), the method for manufacturing a fiber-reinforced resin material including a coating step applying a coating of a paste (P1) on a first sheet (S11) conveyed in a predetermined direction, a cutting step for cutting a long fiber bundle (CF) using a cutter (113A), a scattering step for dispersing the cut fiber bundles (CF) and scattering the cut fiber bundles (CF) on the paste (P1), and an impregnation step for pressing a fiber bundle group (F1) and the paste (P1) on the first sheet (S11) and impregnating the paste (P1) between the fiber bundles (CF).
