Abstract
Description
一種の炭素繊維複合材料の高圧水素貯蔵タンクは、タンク本体を備え、タンク本体は一端に気体誘導口が開設されており、タンク本体の内腔に、タンク本体の強度を高めるのに用いられる補強部材が設けられており、補強部材のサイドエンドは、タンク本体の内壁に固接されており、タンク本体および補強部材はいずれも炭素繊維複合材料が使用されている。
ステップS1では、タンク本体の強度を高めるのに用いられる補強部材を加工かつ硬化する。補強部材には、複数のキャビティ予備成形用溝が形成されている。
ステップS2では、シリコンエアバッグに高圧空気を充填しながら圧力を継続的に保持し、シリコンエアバッグを膨張させ、シリコンエアバッグの表面に炭素繊維複合材料を用いた一次包糸を行い、第一予備成形層を形成することにより、タンク本体のキャビティ予備成形部材を作成する。
ステップS3では、ステップS2で作成したキャビティ予備成形部材を、ステップS1で作成した補強部材のキャビティ予備成形用溝に組み合わせて予備成形することで、タンク本体予備成形部材を作成する。
ステップS4では、ステップS3で作成したタンク本体予備成形部材の表面に炭素繊維複合材料を用いて二次包糸を行い、第二予備成形層を形成し、タンク本体予備成形部材の気体誘導口が位置するところにおいて、第一予備成形層と第二予備成形層との間に金属気体誘導管を埋設する。
ステップS5では、ステップS4で二次包糸完了したタンク本体予備成形部材に対して焼成硬化を行い室温まで冷却させ、炭素繊維複合材料を用いて第二予備成形層の表面を巻きつくことで外部巻付層を形成し、外部巻付層が金属気体誘導管の外側表面まで延伸する。
ステップS6では、ステップS5で巻付き完了したタンク本体予備成形部材に対して焼成硬化を行い室温まで冷却させ、シリコンエアバックの空気を抜き出し、かつシリコンエアバックを取り出し、完成したタンク本体に対して仕上げ加工を行う。
1.本発明の一種の炭素繊維複合材料の高圧水素貯蔵タンクおよびその製造方法では、水素貯蔵タンクは、内層が中空吹き込み、外層が巻付けであるマルチプロセス共硬化成形技術を採用し、内外層の繊維を緻密かつ円滑にし、製品強度を向上させることができる。タンク本体の内腔にはタンク内壁の両端を連結支持する補強材が設けられ、タンク本体の内壁には周方向に環状補強部材が設けられ、水素貯蔵タンクの全体の強度及び剛性をさらに向上させ、水素貯蔵タンクの高圧でのさらなる安全性および信頼性を保障する。
2.本発明の一種の炭素繊維複合材料の高圧水素貯蔵タンクおよびその製造方法では、水素貯蔵タンクは、金属気体誘導管部分以外はすべて高級炭素繊維複合材料が用いられる。従来のタンク本体の様々な異なる材料間の層間結合問題を解決しただけでなく、炭素繊維複合材料の質量が軽いため、水素貯蔵タンクの重量をさらに軽減し、運送が便利となる。
3.本発明の一種の炭素繊維複合材料の高圧水素貯蔵タンクおよびその製造方法では、金属気体誘導管は、曲り角のところにおいて、タンク本体との間にガスケットが埋設されており、外部巻付層には、金属気体誘導管の陥没部に引っ掛かる突起部が設けられており、タンク本体と金属気体誘導管との密封性を高める。
タンク本体1を備え、タンク本体1は一端に気体誘導口11が開設されている。タンク本体1の内腔に、タンク本体1の強度を高めるのに用いられる補強部材2が設けられている。補強部材2のサイドエンドは、タンク本体1の内壁に固接されている。タンク本体1および補強部材1はいずれも炭素繊維複合材料が使用されている。
