Description
上記特許文献1の手法は、表層の気泡をある程度除去するものであるが、炭素繊維層内部の気泡まで除去するものではなかった。また、特許文献1の手法では炭素繊維層内に強度に寄与しない消泡剤が残留するという問題があった。
ライナーに熱硬化性樹脂に含浸させた炭素繊維を巻きつけて硬化前炭素繊維層を形成する、硬化前炭素繊維層形成工程と、
前記硬化前炭素繊維層上に、熱硬化性樹脂に含浸させたガラス繊維を巻きつけて硬化前ガラス繊維層を形成する、ガラス繊維層形成工程と、
内部に多孔質金属を備える筒状のピンを、前記硬化前ガラス繊維層側から前記硬化前炭素繊維層の界面まで挿入する、ピン挿入工程と、
前記ピンからガスを吸引する、ガス吸引工程と、
前記ピンを抜き取った後、熱硬化処理を行ってガラス繊維層及び炭素繊維層を形成する、熱硬化処理工程と、を備える。
当該ガス排出工程によれば、ピンの表面に付着した熱硬化性樹脂を除去することができ、当該ピンを用いて次の高圧タンクを連続的に製造することが可能となる。
このような温度管理を行うことで、熱硬化性樹脂が低粘度状態となり、気泡が表面に移動しやすくなって、ガス吸引が容易となる。
まず図1を参照して、第1の実施形態に係る高圧タンクの製造方法の概要を説明する。図1は、第1の実施形態に係る高圧タンクの製造方法を示すフローチャートである。第1の実施形態に係る高圧タンクの製造方法は、硬化前炭素繊維層形成工程(S10)と、硬化前ガラス繊維層形成工程(S20)と、ピン挿入工程(S30)と、ガス吸引工程(S40)と、熱硬化処理工程(S50)とをこの順に実施するものであり、必要に応じて他の工程を実施してもよいものである。
図6Aの例に示されるように、硬化前ガラス繊維層形成工程後の積層体は、積層する炭素繊維間や、硬化前炭素繊維層19と硬化前ガラス繊維層14との間に気泡17が含まれている。
このような観点から、ガス吸引工程において、硬化前炭素繊維層19の温度を、前記熱硬化性樹脂のガラス転移温度より高く、硬化開始温度より低い温度に調整することが好ましい。このように温度調整することにより、熱硬化性樹脂を低粘度状態とすることができる。その結果、硬化前炭素繊維層19の内部の気体が上昇しやすくなり、ピン30による気体の除去が促進される。
硬化前ガラス繊維層形成後のタンク50を図2のホルダー40に固定し、ピンを挿入してガス吸引を開始する。吸引開始後にワークを加熱し、熱硬化性樹脂が低粘度状態となる温度で保持することが好ましい。熱硬化性樹脂の低粘度状態で温度を保持することにより、炭素繊維層中のガスの吸引が促進される。十分に気体を吸引した後、熱硬化性樹脂が硬化する温度まで加熱する。ピン30を抜き取りは、ガラス繊維層の表層が硬化し始めたときに行うことが好ましい。図6Cの例に示されるようにピン30の抜き取り後、ガラス繊維層には孔15が形成される。当該孔は炭素繊維層13中の気体の排出口となるため、炭素繊維層の硬化開始後であっても脱気を継続することができる。熱硬化性樹脂が十分に硬化するまで熱処理を行うことにより、高圧タンクが得られる。
