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 has an object to provide a laminated molded body in which a thin fiber reinforced layer is laminated and having a favorable strength characteristic. The laminated molded body (1) includes a laminated portion (a laminated portion of SR1 on an upper side and SR1, for example) in which fiber reinforced layers SR1 to SRn, each having a thickness of 20 to 80 μm in which a reinforcing fiber material is dispersed in a thermosetting resin material which serves as a matrix, are laminated, and a laminated portion in which a resin layer is laminated between the fiber reinforced layers (a laminated portion of SR2 on the upper side, TP1, and SR3, for example).

Abstract: A method and a device for opening a fiber bundle, capable of performing a fluctuating operation, at a high speed, of pushing a part of a conveyed fiber bundle by a contact member into a stress state and then separating the contact member from the fiber bundle so as to temporarily relax the fiber bundle, and also capable of reducing damage to the fiber bundle. The device for opening a fiber bundle includes a conveying portion 5 for pulling out a fiber bundle Tm from a yarn feeding body 11 and conveying it in a fiber length direction, a fiber-opening processing portion 3 for opening the fiber bundle by moving a fiber in a width direction while bending the fiber by letting a fluid pass through the conveyed fiber bundle Tm, and a fluctuation imparting portion 4 for rotating a contact member 42 in a direction inclined with respect to a conveyance direction while bringing it into contact with the conveyed fiber bundle Tm and pushing a part of the fiber bundle Tm into a stress state, and then separating the contact member 42 from the fiber bundle Tm in the stress state so as to temporarily bring the fiber bundle Tm into a relaxed state.

Abstract: A method and apparatus for manufacturing a formed article of a composite material. The formed article is manufactured by heating and pressurizing a thermoplastic resin material and fabric material. The method includes a preforming process in which the material to be formed is put in a preforming mold with a release sheet arranged between the material and a part of the preforming mold. The material is heated and pressurized to impregnate the thermoplastic resin material into the fabric material, thus forming an impregnated intermediate material. Then, in a transport process the impregnated intermediate material in a heated state is taken out from the preforming mold with the release sheet left attached thereto, and transported. Finally there is a forming process in which the impregnated intermediate material is accommodated in the forming mold and the impregnated intermediate material is formed into the formed article of the composite material by pressurizing.

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.
