Description
複数の成形型の各々に前記複合材を沿わせて、前記複数の成形型を加熱し、複数の複合材の樹脂を半硬化状態にする工程と、
前記複数の複合材の樹脂を半硬化状態にした後に前記複合材が沿った状態の前記複数の成形型を組み合わせて加熱し、前記複数の複合材を接合する工程と、
を備え、
前記複数の複合材の樹脂を半硬化状態にする際に用いる前記複数の成形型と、前記複数の複合材を接合する際に用いる前記複数の成形型とは共通である。
例えば、上記実施の形態では、第3の複合材20の樹脂を半硬化状態にして第1の複合材11と第2の複合材15との間に介在させたが、第3の複合材20の樹脂を完全硬化状態にして第1の複合材11と第2の複合材15との間に介在させてもよい。
例えば、上記実施の形態では、第1の複合材11、第2の複合材15及び第3の複合材20を接合する際に空間S2にインナーバック21を配置した形態を説明したが、第1の成形型12及び第2の成形型16に比べて熱膨張率が大きいマンドレルなどの押圧部材を空間S2に配置してもよい。
例えば、上記実施の形態の接着部材6は、接着シートで構成したが、接着シートに限らず、複合体の成形品を接合する際に用いられる接着部材を用いることができ、ペースト状、又はフィルム状であってもよい。また、複合材相互を当該複合材の樹脂で接合できる場合は、接着部材6を省略してもよい。
例えば、上記実施の形態では、第1の成形型12の加熱部12b及び第2の成形型16の加熱部16bは、熱媒体として気体や液体を供給して加熱する構成とされているが、第1の成形型12及び第2の成形型16を直接的に加熱することができる構成であればよく、例えば、第1の成形型12及び第2の成形型16に埋め込まれた電熱線などを備えるヒータでもよい。
例えば、上記実施の形態では、接合体として翼1を製造したが、複合材相互を接合して製造される接合体であればよい。そのため、接合体の形状に応じて、複合材や成形型の数は、適宜、変更することができる。また、接合体の形状に応じて、複合材の樹脂を半硬化状態にする際に複数の成形型を組み合わせなくてもよい。
