Description
図1は、本発明の一実施態様に係る繊維強化樹脂の製造方法を示している。上型1と下型2からなる成形型3内に、例えば複数の強化繊維材の積層体からなる強化繊維基材4が配置され、強化繊維基材4の一表面に対面する方向に上型1に開設された注入口5から、成形すべき繊維強化樹脂のマトリックス樹脂となる樹脂が注入され、注入された樹脂が強化繊維基材4中に含浸される。注入口5の直下に位置する強化繊維基材部分が厚み方向に少なくとも部分的に予め除去されることにより、成形型3内の強化繊維基材4中に注入樹脂通過用空間6が形成される。本実施態様では、注入樹脂通過用空間6は、強化繊維基材4を厚み方向に貫通して形成されている。注入口5から注入された樹脂7は、この注入樹脂通過用空間6を通して強化繊維基材4中に含浸される。本実施態様では、注入樹脂通過用空間6が強化繊維基材4を貫通して形成されているので、注入口5から注入された樹脂7は、注入された直後の初期流動において強化繊維基材4には直接衝突せず、下型2の内面に衝突し(衝突部8)、注入樹脂7の勢いが削がれる。注入口5から注入樹脂通過用空間6内に注入された樹脂7は、注入樹脂通過用空間6から強化繊維基材4中に強化繊維基材4の面内方向へと、樹脂流れ9で示すように含浸されていく。
