Description
図1は、本発明の一実施態様に係るプリフォームの製造方法を示している。図1(A)において、1は下型を示しており、下型1は、三次元立体形状の表面を有しているとともに、凹部2を有している。この下型1上に、所定方向に強化繊維が配列された強化繊維基材からなるシート状構造体3が載置され、該シート状構造体3の少なくとも1箇所(図示例では凹部2の周辺部の2箇所)が、少なくとも1個の上型、図示例では2個の上型4、5によって仮押さえされる。この仮押さえの押圧力は、上型4、5に対しP1、P2に制御され、前述したように、仮押さえにより、シート状構造体3が下型1の表面から浮き上がることは抑えられるが、下型1の表面に沿う方向には移動が許容される保持状態に保たれるように設定される。
2 凹部
3 シート状構造体
4,5,6 上型
11 望ましい賦形形状
Claims (8)
- 所定方向に強化繊維が配列された強化繊維基材からなるシート状構造体を、三次元立体形状でかつ凹部を有する下型と、プレス機構を有する複数の上型によって、前記シート状構造体を前記下型の形状に沿うように賦形するプリフォームの製造方法において、前記下型上に前記シート状構造体を置き、該シート状構造体の少なくとも1箇所を前記上型の少なくとも1個で仮押さえし、仮押さえした箇所以外の前記シート状構造体の少なくとも1箇所を別の上型によって押圧し、しかる後、前記シート状構造体の前記押圧した箇所以外の前記下型の前記凹部上に位置する箇所でかつ前記仮押さえした箇所以外の箇所をさらに別の上型によって押圧するとともに、前記仮押さえに用いた上型により前記仮押さえした箇所を所定の押圧力で本押さえすることを特徴とする、プリフォームの製造方法。
- 前記シート状構造体を、前記下型の前記凹部の周辺部にて、前記上型の少なくとも1個で仮押さえする、請求項1に記載のプリフォームの製造方法。
- 前記仮押さえを行う上型の押圧力を、仮押さえ用押圧力と本押さえ用押圧力との二段階に制御する、請求項1または2に記載のプリフォームの製造方法。
- 前記仮押さえを行う際、仮押さえを行う上型以外の残りの上型の少なくとも一部を下型に近接させる、請求項1〜3のいずれかに記載のプリフォームの製造方法。
- 前記シート状構造体を構成する強化繊維基材が強化繊維織物を含む、請求項1〜4のいずれかに記載のプリフォームの製造方法。
- 前記シート状構造体を構成する強化繊維基材が炭素繊維基材を含む、請求項1〜5のいずれかに記載のプリフォームの製造方法。
- 前記シート状構造体が強化繊維基材の積層体からなる、請求項1〜6のいずれかに記載のプリフォームの製造方法。
- RTM成形用のプリフォームを製造する、請求項1〜7のいずれかに記載のプリフォームの製造方法。
