Abstract:
The purpose of the present invention is to provide a production method for a fiber reinforced resin sheet material, the method being capable of continuously and stably obtaining the fiber reinforced resin sheet material by using a fiber sheet material and a resin sheet material and melting the resin sheet material and impregnating or semi-impregnating the same into the fiber sheet material. The method includes the steps of: superimposing a fiber sheet material Ts and a resin sheet material Js, sandwiching these materials between conveying belts 7 and conveying the same; heating and pressing these materials between the heating rolls 1; and after the above steps, cooling and pressing the resulting material between cooling rolls 2 and thereby melting and impregnating or semi-impregnating the resin sheet material Js into the fiber sheet material Ts and thereby obtaining a fiber reinforced resin sheet material Ps, in which side end portions 8, 9 of the fiber sheet material Ts are arranged outside side end portions 10, 11 of the resin sheet material Js, respectively, and the fiber sheet material Ts and the resin sheet material Js are superimposed.

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 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.
