Description
また、本発明の実施形態に係る複合材の成形方法は、前記複合材の成形装置を用いて複合材の被成形品を製造するものである。
また、本発明の実施形態に係る複合材の成形方法は、密閉体により密閉された成形対象品を容器内に搬入するステップと、加熱媒体として水蒸気を前記容器内に供給して前記成形対象品を加熱する一方、前記容器内において前記密閉体で囲まれた領域を減圧することによって前記成形対象品の曲げ成形を行うステップと、前記加熱媒体の温度の制御値を、前記成形対象品の前記曲げ成形に適した値に設定した後、前記成形対象品の加熱硬化に適した値に設定することによって、前記曲げ成形後における加圧下の前記成形対象品を前記容器内において前記加熱媒体で加熱硬化するステップとを有するものである。
図1は本発明の実施形態に係る複合材の成形装置の構成図である。
加熱媒体Hとして水蒸気に加えて混合ガスを用いる場合における加熱媒体Hの圧力の制御値は、成形対象品の曲げ成形に適した値に設定された後、成形対象品の加熱硬化に適した値に設定される。但し、成形対象品の曲げ成形時における加熱媒体Hの圧力と、成形対象品の加熱硬化時における加熱媒体Hの圧力とを、同一の制御値に設定してもよい。加熱媒体Hの圧力の制御値を大気圧よりも大きく設定すれば、上述したように、プリプレグPの曲げ成形を行うための加圧及び曲げ成形後におけるプリプレグPへの硬化のための加圧を、減圧対象領域R内における負圧のみならず、加熱媒体Hの圧力によって行うことができる。
次に複合材の成形装置1を用いて複合材の被成形品を製造する複合材の成形方法について説明する。ここでは、加熱媒体Hとして水蒸気を用いる場合を例に説明する。
このため、複合材の成形装置1及び複合材の成形方法によれば、同一の圧力容器内においてプリプレグPの曲げ成形及び硬化の双方を行うことができる。すなわち、従来は、専用の曲げ成形装置を用いてシート状のプリプレグPの積層体を所定の温度まで加温して賦型する工程と、オートクレーブ処理によって賦型後におけるプリプレグPの加圧下における加熱硬化を行う工程とを別々に行う必要があったが、複合材の成形装置1及び複合材の成形方法によれば、1つの工程でプリプレグPの曲げ成形及び加圧下における加熱硬化を行うことが可能となる。この結果、工程の数が減り、折り曲げた形状や湾曲した形状等の複雑な構造を有する複合材の被成形品をより簡易に製造することが可能となる。
