PROBLEM TO BE SOLVED: To ensure that each layer of a fiber substrate group composed of fiber substrates used for fiber reinforced resin molding by resin injection method is sufficiently impregnated with a resin.SOLUTION: In a plurality of fiber substrates 20 each being a raw material that has arranged fiber bundles 21 and constitutes a fiber reinforced resin together with a resin, when the fiber bundles 21 are continuously laminated one upon another in the same direction, the fiber substrates 20 are integrated together in a state in which the position of a boundary part 21B between the fiber bundle 21 and the fiber bundle 21 adjacent to each other in the arrangement direction is matched between the fiber substrates 20.SELECTED DRAWING: Figure 4
【課題】樹脂注入法による繊維強化樹脂成形に用いられる繊維基材からなる繊維基材群の各層に樹脂を十分に含浸させること。【解決手段】配列された繊維束21を有し、樹脂と共に繊維強化樹脂を構成する素材である複数の繊維基材20が、繊維束21を同一方向に向けて連続して積層されるにあたり、配列方向に隣り合う繊維束21と繊維束21との境界部21Bの位置を繊維基材20同士の間で合わせた状態で、複数の繊維基材20を一体化する。【選択図】図4
