Abstract: A molding method for a composite sheet used for manufacturing a thermosetting resin prepreg sheet in which a thermosetting resin material is impregnated into a fiber sheet includes: bringing a resin transfer sheet in which the thermosetting resin material of a predetermined thickness is carried on one surface of a transfer sheet into contact with one surface of the fiber sheet to be stacked on the fiber sheet. The resin transfer sheet and the fiber sheet in the stacked state are subjected to a heating treatment or heating and pressurizing treatment. The resin transfer sheet and the fiber sheet in the heated and stacked state is subjected to a cooling treatment or cooling and pressurizing treatment so that the thermosetting resin material is transferred to the fiber sheet and the thermosetting resin material is made to adhere to one surface side of the fiber sheet.

Abstract: According to one implementation, a fiber width adjustment device includes: a feeder and an adjuster. The feeder feeds a tape material in a length direction of the tape material. The tape material consists of fibers for a fiber reinforced resin after or before the fibers are impregnated with a resin. The adjuster has a path for the tape material. The path is formed by at least a bottom and a pair of wall surfaces. The interval of the wall surfaces decreased gradually. The width of the tape material which passed the path is changed by adjusting a part of the path. The tape material passes through the part of the path while contacting with the bottom and the wall surfaces.

Abstract: The present invention is intended to provide automated lamination method and device that can efficiently perform automated lamination by using a thin-layer tape. A thin-layer tape automated lamination device 1 includes a provisional formation unit 2 configured to form lamination tapes having thicknesses different from each other by laminating a plurality of thin-layer tapes each having a thickness of 5 μm to 80 μm, and a lamination-shaping unit 3 configured to laminate and shape each formed lamination tape in a lamination region of a basal body surface.

Abstract: A quasi-isotropic reinforced sheet material T formed by integrating a plurality of chopped semi prepreg sheet materials C including a reinforced fiber material and a thermoplastic resin material set in an unimpregnated state such that fiber directions of the reinforced fiber materials are oriented randomly in the two-dimensional direction. The average number of fibers in a thickness direction for materials C ranges is from two to ten and a thickness “t”, relative to the thickness (tp) in an impregnated state, is in a range of tp
