- 下型にゲルコート塗装をしてから強化繊維シートを敷設するとともに所定の位置に置き駒を配し、その後上型を被せて上下両型の外周側重ね合わせ部分を所定の手段で密着させ、注入口から熱硬化性樹脂を注入して強化繊維シートに含浸させながら型内部総てに亘って充填した後、所定の温度で加熱し前記熱硬化性樹脂を硬化させてFRP成形品を得るRTM成形方法において、
前記熱硬化性樹脂はフェノール樹脂であり、前記置き駒は、軟質樹脂製の駒と硬質樹脂製の駒の組み合わせからなり前記型内部でアンダー部分を有した隙間空間を埋めるように配置されるものとされ、前記軟質樹脂製の駒はその一部を前記アンダー部分に挿入して適用され、前記硬質樹脂製の駒はその一部を前記軟質樹脂製の駒に密着した状態でこれに組み合わされるものとされ、且つ、前記上型の型内部中央位置には前記熱硬化性樹脂を注入するための注入口が開口し、前記上型の型内部両端側には注入作業による余分な空気や過剰な樹脂を排出するための排出口が開口しており、前記排出口に接続した吸引ラインの吸引圧力と前記注入口の注入圧力を変更させながら前記熱硬化性樹脂の充填を行い、脱型の際には、先に前記硬質樹脂製の駒を取り外してから前記軟質樹脂製の駒を弾性変形させながら取り外す、ことを特徴とするRTM成形方法。
