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 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

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.
