Abstract
Description
図1は、実施形態に係る繊維強化樹脂成形品の一例としての高圧タンクの製造装置を示す縦断面図である。
図2は、実施形態に係る繊維強化樹脂成形品の一例としての高圧タンクの製造方法を説明するフローチャートである。また、図3〜図7はそれぞれ、プリフォーム配置工程および真空脱気工程、仮締め状態での樹脂注入工程、上型下降および下型コア下降状態での樹脂注入工程、上型下降および下型コア上昇状態での樹脂注入工程、本締めおよび樹脂注入停止工程並びに樹脂硬化工程の状態を示す縦断面図である。
まず、前述した構成の下型コア13を有する下型11と上型12とからなる金型10を用意する。
また、前述したように、ライナーの外表面に繊維を巻き付ける(巻回する)ことによって繊維層を形成したプリフォーム2を予め用意する。
次に、制御装置90が温度制御装置40を制御することによって、金型10(下型11、上型12)を所定温度に保温する。樹脂3が熱硬化性樹脂である場合、この所定温度は、樹脂3の硬化温度以上の温度である。
続いて、制御装置90が搬送機構20と駆動機構30を制御することによって、プリフォーム2を金型10内(つまり、下型11と上型12との間)に配置する(図1、図3)。具体的には、上型12を開いた状態で、搬送機構20が、制御装置90の制御に従って、下型11にプリフォーム2を載置する。このとき、プリフォーム2がシャフト25により軸支される。その後、駆動機構30が、制御装置90の制御に従って、型締めを開始し、上型12を仮締めする。仮締めとは、上型12が開いた状態と本締めの状態との中間的な状態であって、下型11と上型12とが隙間を空けた状態として、図3に示すように、上型12とプリフォーム2との間に数mmの隙間(第2の隙間)が空く位置に移動させることである。この上型12とプリフォーム2との間に形成される隙間(第2の隙間)は、下型11とプリフォーム2との隙間(第1の隙間)よりも大きい。
次に、上記の仮締めの状態において(言い換えれば、型締め完了前に)、制御装置90が真空ポンプ50を制御することによって、金型10内を真空脱気する(図3)。
上記の真空脱気停止(完了)後、樹脂3を金型10内に射出・注入する(図4)。具体的には、制御装置90は、開閉バルブ65を開き、樹脂溜まり62に貯留されている主剤を加圧装置63によって加圧し、樹脂溜まり67に貯留されている硬化剤を加圧装置68によって加圧し、主剤と硬化剤を混合して(未硬化の)樹脂3とする。これによって、上型12に設けられた樹脂注入配管16内を(未硬化の)樹脂3が流れ、ゲート(図示例では、プリフォーム2の中央部に設けられたゲート)14から、プリフォーム2に向けて樹脂3が射出・注入される。上型12が仮締めであるため、上型12とプリフォーム2(の上面)との間に形成された隙間(第2の隙間)に向けて樹脂3が射出・注入される。
次に、制御装置90が駆動機構30を制御することによって、上型12を閉じながら(射出圧縮)、下型11に設けられた下型コア13を下降(すなわち、プリフォーム2から相対的に離間)させる(図5)。これによって、下型コア13とプリフォーム2との隙間(第3の隙間)が増大し(換言すれば、下型コア13とプリフォーム2との間に第1の隙間よりも大きい数mm程度の第3の隙間が形成され)、プリフォーム2の上面から樹脂含浸させながら、下型11(特に下型コア13)とプリフォーム2(の下面)の隙間にも樹脂3を均一に充填する。このとき、プリフォーム2の上面側の樹脂3の圧力を緩和させると共に、プリフォーム2の下面側にも樹脂3を均一に流動させるため、圧力センサ18でプリフォーム2の上面側の(つまり、上型12とプリフォーム2との間に注入された)樹脂3の圧力を検知しながら、下型コア13を下降させる。例えば、制御装置90は、圧力センサ18の検知圧力(樹脂圧力)に基づいて、上型12や下型コア13の下降速度等を制御可能である。
続いて、制御装置90が駆動機構30を制御することによって、上型12を下降端まで下降して型を閉じつつ、同時に、下型11に設けられた下型コア13を(下型11のキャビティー面と同一面となる元の位置まで)上昇(すなわち、プリフォーム2に相対的に接近)させる(図6)。このとき、圧力センサ18でプリフォーム2の上面側の樹脂3の圧力を検知すると共に、圧力センサ17でプリフォーム2の下面側の樹脂3の圧力を検知する。そして、それら圧力センサ18、17で検知された樹脂3の圧力が一致するように、上型12を下降および下型コア13を上昇させる(すなわち、上型12および下型コア13を共にプリフォーム2に相対的に接近させる)。これによって、金型10内の樹脂3が均一に圧縮充填され、プリフォーム2の繊維層内に含浸する。例えば、制御装置90は、上型12および下側コア13を共に(同時に)閉じてプリフォーム2に接近させる際、圧力センサ18、17の検知圧力(樹脂圧力)に基づいて、上型12の下降速度や下型コア13の上昇速度等を制御可能である。
樹脂3の充填が完了した後、制御装置90が駆動機構30を制御することによって、上型12および下型11に設けられた下型コア13を完全に型締め(本締め)する。そして、樹脂3が繊維層内に含浸完了後、樹脂3の注入を停止する(図7)。
前述の樹脂3の注入停止後、樹脂3を硬化させる(図7)。
樹脂3が硬化した後、制御装置90が駆動機構30を制御することによって、上型12を開く。樹脂3の硬化が完了することで、ライナーの外周に繊維強化樹脂層が形成された高圧タンク4が得られる。
