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: A method for producing a molded article of a fiber-reinforced plastic include molding a fiber-resin mixture containing an inorganic reinforcing fiber and a thermosetting resin under heat and pressure. The elapsed time since the thermosetting resin reached a molding temperature at which a hardening reaction proceeds is measured, the loss angle δ of the thermosetting resin is measured in a dynamic viscoelasticity measurement, and the relationship between the elapsed time and the loss angle δ is evaluated to calculate the range of the elapsed time, within which the loss angle δ is 0.55 to 1.57 rad after the loss angle δ reached the maximum value, as the pressurization start range. The fiber-resin mixture is heated to the molding temperature and pressure application to the fiber-resin mixture is started within the pressurization start range, to obtain the molded article of the fiber-reinforced plastic.

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.
