強化繊維に熱硬化性樹脂を含浸させたプリプレグの製造方法において、In a method for producing a prepreg in which a reinforcing fiber is impregnated with a thermosetting resin, 片面に熱硬化性樹脂を塗布した一対の担持シートで強化繊維を挟持して、積層体を形成する工程と、 Sandwiching reinforcing fibers with a pair of support sheets coated with a thermosetting resin on one side to form a laminate; and 前記積層体に張力をかけながら、前記積層体を加熱する工程と、 Heating the laminate while applying tension to the laminate; 前記積層体を加熱、加圧することにより、強化繊維に熱硬化性樹脂を含浸させ、プリプレグを生成する工程とを有することを特徴とするプリプレグの製造方法。 A method for producing a prepreg comprising the step of impregnating a reinforcing fiber with a thermosetting resin by heating and pressurizing the laminate to produce a prepreg.前記積層体に張力をかけながら、前記積層体を加熱する工程を、隣接する前記加熱部材が前記積層体の異なる面に接し、かつ、隣接する前記加熱部材間を通過する時の前記積層体の進行方向がその直前の進行方向と異なるように配置されている、複数の加熱部材により行う、請求項１記載のプリプレグの製造方法。The step of heating the laminated body while applying tension to the laminated body includes the step of heating the laminated body when the adjacent heating members are in contact with different surfaces of the laminated body and pass between the adjacent heating members. The manufacturing method of the prepreg of Claim 1 performed by the several heating member arrange | positioned so that the advancing direction may differ from the advancing direction immediately before it.前記加熱部材に対して前記積層体が押し付けられる圧力が０．０１〜０．５ｋｇ／ｃｍThe pressure with which the laminate is pressed against the heating member is 0.01 to 0.5 kg / cm.22であることを特徴とする請求項２に記載のプリプレグの製造方法。The method for producing a prepreg according to claim 2, wherein:前記加熱部材の前記積層体と接する面が曲面である請求項２又は請求項３に記載のプリプレグの製造方法。The method for producing a prepreg according to claim 2 or 3, wherein a surface of the heating member that contacts the laminated body is a curved surface.
