しかしながら、従来技術では、タンクを冷却する際に、タンクの内部と外部に温度差が生じるため、タンクの繊維強化樹脂層に大きな残留歪みが発生してしまう可能性があるという問題があった。   However, the conventional technique has a problem that when the tank is cooled, a temperature difference is generated between the inside and the outside of the tank, so that a large residual strain may occur in the fiber reinforced resin layer of the tank.

本発明は、上述の課題の少なくとも一部を解決するためになされたものであり、以下の形態として実現することが可能である。   SUMMARY An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the invention can be implemented as the following forms.

（１）本発明の一形態によれば、タンクの製造方法が提供される。このタンクの製造方法は、ライナの外周に未硬化の熱硬化性樹脂を含浸した繊維束が巻回されたタンクを加熱し、前記熱硬化性樹脂を硬化させて繊維強化樹脂層を形成する工程と、前記タンクを外部から冷却しつつ、前記タンクの内部に液体を注入して前記タンクを内部から冷却することによって、前記タンクを前記熱硬化性樹脂の軟化温度まで冷却する工程と、前記タンクを前記軟化温度で一定期間保持する工程とを備える。 (1) According to one form of this invention, the manufacturing method of a tank is provided. The tank manufacturing method includes a step of heating a tank in which a fiber bundle impregnated with an uncured thermosetting resin is wound around the outer periphery of a liner, and curing the thermosetting resin to form a fiber reinforced resin layer. Cooling the tank to the softening temperature of the thermosetting resin by injecting liquid into the tank and cooling the tank from the inside while cooling the tank from the outside, and the tank Holding for a certain period of time at the softening temperature.

この形態のタンクの製造方法によれば、タンクを外部から冷却しつつ、タンクの内部に液体を注入してタンクを内部から冷却することで、タンクの内部と外部との温度差を減少し、繊維強化樹脂層に大きな残留歪みが生じるのを抑制できる。また、タンクを熱硬化性樹脂の軟化温度で一定期間保持するので、繊維強化樹脂層に残留歪みが生じても、それを緩和することができる。   According to the method of manufacturing a tank of this embodiment, while cooling the tank from the outside, by injecting liquid into the tank and cooling the tank from the inside, the temperature difference between the inside and outside of the tank is reduced, Generation of a large residual strain in the fiber reinforced resin layer can be suppressed. In addition, since the tank is held at the softening temperature of the thermosetting resin for a certain period, even if residual strain occurs in the fiber reinforced resin layer, it can be mitigated.

本発明は、上記以外の種々の形態で実現することも可能である。例えば、タンクの製造装置、タンクの冷却制御装置、タンクの冷却方法等の形態で実現することができる。   The present invention can be implemented in various forms other than the above.

・第１実施形態：
図１は、本発明の第１実施形態の製造方法で得られるタンク１００の概略構成を示す断面図である。このタンク１００は、例えば、燃料電池車両に搭載され、燃料ガスである水素を貯蔵する高圧タンクとして用いられる。 First embodiment:

The tank 100 is mounted on a fuel cell vehicle, for example, and is used as a high-pressure tank that stores hydrogen as a fuel gas.

タンク１００は、両端に半球状のドーム部を有する略円筒状の形状を有し、ライナ１０を繊維強化樹脂層３０で被覆して構成されている。ライナ１０は、内部中空であり、長手方向の両端に口金２１，２２が配置されている。口金２１，２２は、略円柱状の形状を有し、例えばステンレス鋼やアルミニウムなどの金属で形成される。第１の口金２１は、ライナ１０の内部に導通する貫通孔２３を有しており、配管（後述）が挿入可能である。第２の口金２２は、長手方向の両端にそれぞれ有底状の凹部２４，２５を有しており、凹部２４の内周面には雌ねじが設けられている。凹部２４には、回転支持棒（後述）がねじ込み接続可能であり、凹部２５には、配管の端部が挿入可能である。   The tank 100 has a substantially cylindrical shape having hemispherical dome portions at both ends, and is configured by covering the liner 10 with a fiber reinforced resin layer 30. The liner 10 is hollow inside, and caps 21 and 22 are disposed at both ends in the longitudinal direction. The bases 21 and 22 have a substantially cylindrical shape, and are formed of a metal such as stainless steel or aluminum. The 1st nozzle | cap | die 21 has the through-hole 23 which conduct | electrically_connects inside the liner 10, and piping (after-mentioned) can be inserted. The second base 22 has bottomed concave portions 24 and 25 at both ends in the longitudinal direction, and a female screw is provided on the inner peripheral surface of the concave portion 24. A rotation support rod (described later) can be screwed into the recess 24 and a pipe end can be inserted into the recess 25.

繊維強化樹脂層３０は、ライナ１０の外周を覆うように繊維強化樹脂材料を巻回した後、加熱して硬化させることによって形成される。繊維強化樹脂材料としては、未硬化の熱硬化性樹脂を含浸した繊維束、例えば炭素繊維とエポキシ樹脂を含む炭素繊維強化プラスチック（ＣＦＲＰ：carbon-fiber-reinforced plastic）の束を利用することが可能である。   The fiber reinforced resin layer 30 is formed by winding a fiber reinforced resin material so as to cover the outer periphery of the liner 10 and then curing it by heating. As the fiber reinforced resin material, it is possible to use a fiber bundle impregnated with an uncured thermosetting resin, for example, a bundle of carbon fiber-reinforced plastic (CFRP) containing carbon fiber and epoxy resin. It is.

図２は、タンク１００の製造装置２００を示す説明図である。製造装置２００は、加熱炉２１０と、液体供給系２３０と、液体排出系２４０と、制御装置２２０とを備えている。加熱炉２１０は、タンク１００を加熱又は冷却するための装置である。加熱炉２１０の内部には、加熱機１９０と、冷却機１７０と、放射温度計１６０とが設けられている。加熱機１９０は、加熱炉２１０の内壁に設置され、例えばタンク１００にマイクロ波を照射して加熱する。冷却機１７０は、加熱炉２１０の内壁に設置され、タンク１００に向けて複数のノズル１７２を備え、冷風ポンプ１８０から供給される冷風を各ノズル１７２からタンク１００に向けて吹き出し、タンク１００を外部から冷却する。放射温度計１６０は、加熱炉２１０内部の温度、すなわちタンク１００外部の温度を測定する。   FIG. 2 is an explanatory view showing a manufacturing apparatus 200 for the tank 100. The manufacturing apparatus 200 includes a heating furnace 210, a liquid supply system 230, a liquid discharge system 240, and a control device 220. The heating furnace 210 is a device for heating or cooling the tank 100. Inside the heating furnace 210, a heater 190, a cooler 170, and a radiation thermometer 160 are provided. The heater 190 is installed on the inner wall of the heating furnace 210, and for example, heats the tank 100 by irradiating it with microwaves. The cooler 170 is installed on the inner wall of the heating furnace 210, and includes a plurality of nozzles 172 toward the tank 100. The cool air supplied from the cold air pump 180 is blown out from the nozzles 172 toward the tank 100, and the tank 100 is externally provided. Cool from. The radiation thermometer 160 measures the temperature inside the heating furnace 210, that is, the temperature outside the tank 100.

液体供給系２３０は、加熱炉２１０の外部に設置されており、タンク１００の内部に液体を供給する。液体供給系２３０には、貯留槽１１０と、ポンプ１２０と、ヒータ１３０と、温度センサ１４０とが設けられている。貯留槽１１０に貯留している液体、例えば純水は、ポンプ１２０によって液体供給系２３０に送り出され、ヒータ１３０によって一定の温度に加熱された後に、調温媒体としてタンク１００の内部に注入される。温度センサ１４０は、調温媒体の温度を測定する。タンク１００内部の温度変化が急激でない場合には、調温媒体の温度をタンク１００内部の温度とみなすことが可能である。液体排出系２４０は、ポンプ１５０を備え、タンク１００の内部に注入された調温媒体を加熱炉２１０の外部に排出する。   The liquid supply system 230 is installed outside the heating furnace 210 and supplies liquid to the inside of the tank 100. The liquid supply system 230 is provided with a storage tank 110, a pump 120, a heater 130, and a temperature sensor 140. A liquid, for example, pure water, stored in the storage tank 110 is sent to the liquid supply system 230 by the pump 120, heated to a certain temperature by the heater 130, and then injected into the tank 100 as a temperature control medium. . The temperature sensor 140 measures the temperature of the temperature control medium. When the temperature change inside the tank 100 is not rapid, the temperature of the temperature control medium can be regarded as the temperature inside the tank 100. The liquid discharge system 240 includes a pump 150 and discharges the temperature control medium injected into the tank 100 to the outside of the heating furnace 210.

制御装置２２０は、中央処理装置と主記憶装置とを備えるマイクロコンピュータによって構成される。制御装置２２０は、放射温度計１６０と温度センサ１４０との温度測定値を用いて、加熱炉２１０内部、液体供給系２３０及び液体排出系２４０の各種機器の動作を制御する。   The control device 220 is configured by a microcomputer including a central processing unit and a main storage device. The control device 220 uses the temperature measurement values of the radiation thermometer 160 and the temperature sensor 140 to control the operation of various devices inside the heating furnace 210, the liquid supply system 230, and the liquid discharge system 240.

タンク１００は、ライナ１０の外周を繊維強化樹脂材料３０ｐで被覆した後に、加熱炉２１０の内部に設置される。加熱する前に、タンク１００の第２の口金２２の凹部２４に、回転支持棒６０の一端部がねじ込んで固定される。回転支持棒６０の他端部は、加熱炉２１０内部にある回転機構に固定されている（図示せず）。また、タンク１００の第１の口金２１の貫通孔２３には、配管４０の一端部が挿入され、貫通孔２３を通過してタンク１００の内部に挿入される。配管４０の他端部は、加熱炉２１０外部に延びて、液体供給系２３０と連結されている。また、配管４０のうち、タンク１００の内部に位置する内部配管４４の外周面には、複数の噴出孔４１が設けられている。また、内部配管４４の第１の口金２１に近い位置には貫通孔４２が設けられており、この貫通孔４２を通して、排出配管５０がタンク１００の下端近くの位置に設置されている。排出配管５０の一端部は配管４０の内部を通して液体排出系２４０と連結されている。液体供給系２３０から供給された調温媒体は、配管４０を通して噴出孔４１からタンク１００内部に注入された後、排出配管５０に吸い取られて液体排出系２４０を通して加熱炉２１０外部に排出される。なお、タンク１００は、回転支持棒６０によって支持されており、回転支持棒６０が回転すると、タンク１００のライナ１０と、口金２１，２２と、繊維強化樹脂材料３０ｐとを含むタンク１００本体が回転支持棒６０と連動して回転する。   The tank 100 is installed inside the heating furnace 210 after the outer periphery of the liner 10 is covered with the fiber reinforced resin material 30p. Before heating, one end of the rotation support rod 60 is screwed into the recess 24 of the second base 22 of the tank 100 and fixed. The other end of the rotation support rod 60 is fixed to a rotation mechanism inside the heating furnace 210 (not shown). In addition, one end of the pipe 40 is inserted into the through hole 23 of the first base 21 of the tank 100, passes through the through hole 23, and is inserted into the tank 100. The other end of the pipe 40 extends outside the heating furnace 210 and is connected to the liquid supply system 230. In addition, a plurality of ejection holes 41 are provided on the outer peripheral surface of the internal pipe 44 located inside the tank 100 in the pipe 40. Further, a through hole 42 is provided at a position near the first base 21 of the internal pipe 44, and the discharge pipe 50 is installed at a position near the lower end of the tank 100 through the through hole 42. One end of the discharge pipe 50 is connected to the liquid discharge system 240 through the inside of the pipe 40. The temperature control medium supplied from the liquid supply system 230 is injected into the tank 100 from the ejection hole 41 through the pipe 40, and then sucked into the discharge pipe 50 and discharged to the outside of the heating furnace 210 through the liquid discharge system 240. The tank 100 is supported by a rotation support rod 60, and when the rotation support rod 60 rotates, the tank 100 body including the liner 10, the bases 21, 22 and the fiber reinforced resin material 30p of the tank 100 rotates. It rotates in conjunction with the support bar 60.

図３は、繊維強化樹脂材料３０ｐの加熱・冷却工程におけるタンク１００の内部温度Ｔｉｎおよび外部温度Ｔｏｕｔの時間変化の一例を示すグラフである。時刻ｔ０では、回転支持棒６０が回転しており、加熱機１９０が運転し始めてタンク１００の繊維強化樹脂材料３０ｐを加熱する。また、制御装置２２０は、ポンプ１２０を駆動し、貯留槽１１０の中の液体をヒータ１３０に送り出して加熱させ、調温媒体として配管４０を経由してタンク１００の内部に注入する。このとき、制御装置２２０は、タンク１００の内部温度Ｔｉｎ（すなわち調温媒体の温度）をタンク１００の外部温度Ｔｏｕｔとほぼ一致させるように制御することが好ましい。なお、調温媒体の注入と同時に、制御装置２２０はポンプ１５０を駆動し、排出配管５０と液体排出系２４０とを経由してタンク１００内部の調温媒体を排出する。   FIG. 3 is a graph showing an example of temporal changes in the internal temperature Tin and the external temperature Tout of the tank 100 in the heating / cooling process of the fiber reinforced resin material 30p. At time t <b> 0, the rotation support rod 60 is rotating, and the heater 190 starts operating to heat the fiber reinforced resin material 30 p in the tank 100. Further, the control device 220 drives the pump 120 to send the liquid in the storage tank 110 to the heater 130 for heating, and injects the liquid into the tank 100 via the pipe 40 as a temperature control medium. At this time, it is preferable that the control device 220 performs control so that the internal temperature Tin (that is, the temperature of the temperature control medium) of the tank 100 substantially matches the external temperature Tout of the tank 100. Simultaneously with the injection of the temperature control medium, the control device 220 drives the pump 150 and discharges the temperature control medium inside the tank 100 via the discharge pipe 50 and the liquid discharge system 240.

加熱を続けると、時刻ｔ１では、タンク１００の外部温度Ｔｏｕｔ及び内部温度Ｔｉｎが熱硬化性樹脂の硬化温度に達し、繊維強化樹脂材料３０ｐの熱硬化性樹脂が硬化し始める。時刻ｔ１から時刻ｔ２までタンク１００の外部温度Ｔｏｕｔを硬化温度で保持し、熱硬化性樹脂の硬化が完成すると、時刻ｔ２から冷却を開始する。時刻ｔ２では、制御装置２２０は加熱機１９０を停止し、冷風ポンプ１８０を駆動して冷却機１７０のノズル１７２から冷風をタンク１００に向けて送出させる。時刻ｔ２から時刻ｔ３まで冷却を続けると、タンク１００の外部温度Ｔｏｕｔ及び内部温度Ｔｉｎが熱硬化性樹脂の軟化温度に達する。時刻ｔ３では、制御装置２２０は冷却機１７０の冷却を停止し、タンク１００の外部温度Ｔｏｕｔと内部温度Ｔｉｎを軟化温度で一定期間ｔｘ保持する。この保持期間ｔｘが終了すると、時刻ｔ４では、制御装置２２０は再び冷却機１７０とポンプ１２０を運転させてタンク１００を冷却する。時刻ｔ５では、タンク１００の外部温度Ｔｏｕｔ及び内部温度Ｔｉｎが室温になり、タンク１００内部へ調温媒体の注入及びタンク１００内部から調温媒体の排出が停止する。これにより、繊維強化樹脂層３０が形成され、タンク１００の製造が完了する。   If the heating is continued, at time t1, the external temperature Tout and the internal temperature Tin of the tank 100 reach the curing temperature of the thermosetting resin, and the thermosetting resin of the fiber reinforced resin material 30p starts to be cured. From time t1 to time t2, the external temperature Tout of the tank 100 is held at the curing temperature, and when the curing of the thermosetting resin is completed, cooling is started from time t2. At time t <b> 2, the control device 220 stops the heater 190, drives the cold air pump 180, and sends the cold air from the nozzle 172 of the cooler 170 toward the tank 100. When cooling is continued from time t2 to time t3, the external temperature Tout and internal temperature Tin of the tank 100 reach the softening temperature of the thermosetting resin. At time t3, the control device 220 stops the cooling of the cooler 170 and holds the external temperature Tout and the internal temperature Tin of the tank 100 at the softening temperature for a certain period tx. When the holding period tx ends, at time t4, the control device 220 operates the cooler 170 and the pump 120 again to cool the tank 100. At time t5, the external temperature Tout and the internal temperature Tin of the tank 100 become room temperature, and the injection of the temperature control medium into the tank 100 and the discharge of the temperature control medium from the tank 100 are stopped. Thereby, the fiber reinforced resin layer 30 is formed and the manufacture of the tank 100 is completed.

以上のように、時刻ｔ２から時刻ｔ３までの冷却の過程では、タンク１００を外部から冷却しつつ、タンク１００の内部に調温媒体を注入し、タンク１００を内部から冷却することで、タンク１００の内部と外部との温度差を減少し、繊維強化樹脂層３０に大きな残留歪みが生じるのを抑制できる。また、タンク１００を熱硬化性樹脂の軟化温度で一定期間ｔｘ保持することによって、繊維強化樹脂層３０に残留歪みが生じても、それを緩和することができる。なお、軟化温度で保持する保持期間ｔｘは、残留歪みを十分に減少できるように経験的又は実験的に予め決定される。   As described above, in the process of cooling from time t2 to time t3, the tank 100 is cooled from the outside, while the temperature control medium is injected into the tank 100 and the tank 100 is cooled from the inside. It is possible to reduce the temperature difference between the inside and the outside of the fiber, and suppress the occurrence of a large residual strain in the fiber reinforced resin layer 30. Moreover, even if residual strain occurs in the fiber reinforced resin layer 30 by holding the tank 100 at the softening temperature of the thermosetting resin for a certain period tx, it can be mitigated. The holding period tx held at the softening temperature is determined in advance empirically or experimentally so that the residual strain can be sufficiently reduced.

・第２実施形態：
図４は、第２実施形態におけるタンク１００の内部温度Ｔｉｎ１および外部温度Ｔｏｕｔ１の時間変化の一例を示すグラフである。図３に示した第１実施形態との違いは、調温媒体の注入が時刻ｔ２から時刻ｔ４までの間（冷却期間を含む）にのみ行われている点であり、これ以外の構成は第１実施形態と同様である。 Second embodiment:
FIG. 4 is a graph showing an example of temporal changes in the internal temperature Tin1 and the external temperature Tout1 of the tank 100 in the second embodiment. The difference from the first embodiment shown in FIG. 3 is that the temperature control medium is injected only from time t2 to time t4 (including the cooling period). This is the same as in the first embodiment.

図４の時刻ｔ０から時刻ｔ１にかけて、タンク１００の内部に調温媒体を注入せずにタンク１００を外部のみから加熱するため、タンク１００の外部と内部には第１実施形態よりも大きな温度差が生じる。このため、第１実施形態よりもタンク１００の繊維強化樹脂層３０に多くの歪みが生じるが、時刻ｔ３から時刻ｔ４の間にタンク１００を熱硬化性樹脂の軟化温度で一定期間ｔｙ保持することで、その歪みを緩和することができる。ただし、歪みを完全に緩和するために、第２実施形態での保持期間ｔｙを第１実施形態での保持期間ｔｘよりも長くすることが好ましい。また、時刻ｔ４から時刻ｔ５までの間では、タンク１００の内部に調温媒体の注入がないため、タンク１００の外部温度Ｔｏｕｔ１及び内部温度Ｔｉｎ１が室温になるまでの時間が第１実施形態よりも長い。これらの点を考慮すると、第２実施形態よりも第１実施形態のほうが好ましい。   Since the tank 100 is heated only from the outside without injecting a temperature control medium into the tank 100 from time t0 to time t1 in FIG. 4, a temperature difference between the outside and inside of the tank 100 is larger than that in the first embodiment. Occurs. For this reason, more distortion occurs in the fiber reinforced resin layer 30 of the tank 100 than in the first embodiment, but the tank 100 is held at the softening temperature of the thermosetting resin for a certain period of time between time t3 and time t4. Thus, the distortion can be reduced. However, in order to completely alleviate the distortion, it is preferable that the holding period ty in the second embodiment is longer than the holding period tx in the first embodiment. Further, since the temperature control medium is not injected into the tank 100 from time t4 to time t5, the time until the external temperature Tout1 and the internal temperature Tin1 of the tank 100 reach room temperature is longer than that in the first embodiment. long. Considering these points, the first embodiment is preferable to the second embodiment.

本発明は、上述の実施形態に限られるものではなく、その趣旨を逸脱しない範囲において種々の構成で実現することができる。例えば、発明の概要の欄に記載した各形態中の技術的特徴に対応する実施形態中の技術的特徴は、上述の課題の一部又は全部を解決するために、あるいは、上述の効果の一部又は全部を達成するために、適宜、差し替えや、組み合わせを行うことが可能である。また、その技術的特徴が本明細書中に必須なものとして説明されていなければ、適宜、削除することが可能である。   The present invention is not limited to the above-described embodiment, and can be realized with various configurations without departing from the spirit of the present invention. For example, the technical features in the embodiments corresponding to the technical features in each embodiment described in the summary section of the invention are intended to solve part or all of the above-described problems, or one of the above-described effects.
