Description

即ち本発明の要旨は、複数の強化繊維を引き揃えてシート状繊維束とし、複数本の前記
シート状繊維束を引き揃えて、かつ横方向に隣接する側端部同士を重ね合わせて配列して
強化繊維シートとし、前記強化繊維シートに、３０℃における粘度が１０ １ 〜１０ ５ Ｐａ・ｓｅｃである樹脂組成物を含浸させてプリプレグを得る、
プリプレグの製造方法、である。 That is, the gist of the present invention is that a plurality of reinforcing fibers are aligned to form a sheet-like fiber bundle, a plurality of the sheet-like fiber bundles are aligned, and the side edges adjacent in the lateral direction are arranged to overlap each other. A reinforced fiber sheet, and the reinforced fiber sheet is impregnated with a resin composition having a viscosity at 30 ° C. of 10 1 to 10 5 Pa · sec to obtain a prepreg.
It is a manufacturing method of a prepreg.
