Description
本発明の他の課題は、樹脂を硬化させて複合材料を製造するときに、その樹脂が硬化する前にその複合材料をより確実に修理し、その修理によるその複合材料の強度の劣化を低減する複合材料製造装置および複合材料製造方法を提供することにある。
本発明の他の課題は、樹脂を硬化させて複合材料を製造するときに、その樹脂が硬化する前にその複合材料をより確実に、かつ、より安価に修理し、その修理によるその複合材料の強度の劣化を低減する複合材料製造装置および複合材料製造方法を提供することにある。
モールド2には、さらに、注入口11と吸引口12とが設けられている。注入口11は、側部8を貫通し、また図示されていない樹脂注入装置とモールド2の含浸空間とを接続している。その樹脂注入装置は、注入口11を介して樹脂を含浸空間に注入する。吸引口12は、図示されていない樹脂吸引装置と含浸空間とを接続している。その樹脂吸引装置は、吸引口12を介して封止された含浸空間を真空排気し、注入された樹脂を含浸空間の外部に吸引する。
尚、モールド2は、側部8を用いない構成とすることもできる。この場合、含浸空間は板部7とバッグフィルム3により封止された内部空間であり、含浸されるべき繊維強化材10が置かれる。注入口11はその含浸空間と図示されていない樹脂注入装置を接続し、吸引口12はその含浸空間と図示されていない樹脂吸引装置とを接続する。
あるいは側部8を可撓性のある材料もしくは不定形の材料で形成してもよい。例としては、ゴム、ワックス、プラスチック系材料、シーラント材が上げられる。
注入側パスメディア5は、含浸空間の底に網状に形成され、注入口11を介して樹脂注入装置から含浸空間に樹脂が一様に注入されることを補助する。この例では、パスメディア5は、含浸空間の底部ではなく、上部に設けてもよい。その場合は、注入口11も上部に配置され、パスメディア5に接続されていることが望ましい。
繊維強化材10は、繊維部分から形成されている。その繊維部分では、炭素繊維で形成された織物が積層されている。なお、その繊維部分は、ガラス繊維、アラミド繊維のような、炭素繊維と異なる他の繊維で形成されてもよい。
更に、繊維強化樹脂中間材22に、比較的大きい未含浸欠陥が形成されることがある。図4は、その比較的大きい未含浸部分43が形成された繊維強化樹脂中間材44を示している。未含浸部分43は、繊維強化樹脂中間材22のうちのバッグフィルム3の近傍に形成される。
図1に示されるように、複合材料製造装置1は、更に、ボイドあるいは未含浸欠陥の存在を検査するための検査装置20を備えている。検査装置20は、例えば、撮像装置であり、バッグフィルム3が透明なとき、含浸空間を上方から撮像して、その画像からボイドや欠陥を検出する。また、検査装置20は、含浸空間の平面位置座標を認識して、ボイド等の位置を知らせることができることが望ましい。含浸空間が大きいときには、検査装置20が平面座標上で動かされ、その動きと連動して位置座標が検出されてもよい。また、検査装置20は、超音波検査装置等の非破壊検査装置であってもよい。よれにより、表面の欠陥ばかりでなく、内部のボイド等を検出することができる。検査装置20は、含浸終了後ばかりでなく、含浸処理中に動作可能であることが望ましい。
複合材料製造装置1は、吸引用ツール32と樹脂吸引装置33と吸引用管34と注入用ツール35と樹脂注入装置36と注入用管37とを備えている。吸引用ツール32は、樹脂含浸の開始後、たとえば、樹脂含浸中にバッグフィルム3に開口が形成され、その開口に取り付けられる。樹脂吸引装置33は、吸引用管34を介して吸引用ツール32に接続されている。注入用ツール35は、樹脂含浸の開始後、たとえば、樹脂含浸中にバッグフィルム3に開口が形成され、その開口に取り付けられる。樹脂注入装置36は、注入用管37を介して注入用ツール35に接続されている。
バッグフィルム3のリーク孔23が塞がれたあと、樹脂吸引装置33は、ユーザに操作されて、吸引用ツール32と吸引用管34とを介して、含浸空間を排気し、樹脂を含浸空間の外部に吸引する。樹脂注入装置36は、ユーザに操作されて、注入用ツール35と注入用管37とを介して、含浸空間に樹脂を注入する。こうして、ボイドが樹脂で埋められる。このとき、注入口11を介して樹脂が含浸空間に注入され、また、吸引口12を介して封止された含浸空間が真空排気されていてもよい。あるいは、注入口11を介しての樹脂の注入と、吸引口12を介しての排気は停止され、あるいは終了されていてもよい。
注入用ツール35は、バッグフィルム46の、未含浸部分43が形成されている領域の中央に配置される。吸引用ツール32は、バッグフィルム46の、未含浸部分43が形成されている領域の縁に配置され、すなわち、パスメディア48が配置されている領域に配置されている。
上記のように、樹脂の含浸が最も遅いと想定されるところに吸引用ツール32が配置される。このため、欠陥の状況により吸引用ツール32の配置は変わっても良い。
樹脂吸引装置33(図示せず)は、ユーザに操作されて、吸引用ツール32と吸引用管34とを介して、含浸空間を排気し、樹脂を含浸空間の外部に吸引する。樹脂注入装置36(図示せず)は、ユーザに操作されて、注入用ツール35と注入用管37とを介して、含浸空間に樹脂を注入する。こうして、未含浸部分43が樹脂で含浸される。このとき、注入口11を介して樹脂が含浸空間に注入され、また、吸引口12を介して封止された含浸空間が真空排気されていてもよい。あるいは、注入口11を介しての樹脂の注入と、吸引口12を介しての排気は停止され、あるいは終了されていてもよい。
本体部分51は、図6に示されているように、内部に空洞55が形成されている。ジョイント部分52は、流路53が形成されている。流路53は、外部を空洞55に接続している。吸引用ツール32は、さらに、多孔性板部56を備えている。多孔性板部56は、剛性が必要であるため、ステンレス鋼で形成され、複数の孔57を有している。すなわち、多孔性板部56は、パンチングメタルから形成されている。多孔性板部56は、本体部分51の円柱のジョイント部分52が形成されている底面と反対側の底面に配置されている。多孔性板部56の複数の孔57は、使用時に含浸空間を空洞55に接続している。なお、多孔性板部56は、多孔性である他の板に置換されることができる。その板としては、金網が例示される。また、多孔性板部の代わりに、使用時に含浸空間を空洞55に接続する複数の孔を有するブロック状の部材を用いることも可能である。
このように、注入用ツール35と吸引用ツール32とは、同様な形状を有し、同様な機能を有するので、一方を他方と兼用してもよい。
複合材料製造装置1を炉の内部に配置し、複合材料製造装置1を加熱しながら、その樹脂注入装置を用いてモールド2の含浸空間に樹脂を注入し、樹脂吸引装置を用いて、モールド2の含浸空間を排気する。その樹脂が吸引口12に到達した後に、その樹脂吸引装置を用いて、その樹脂をモールド2の外部に排出する(ステップS3)。このような樹脂の注入により、その積層された複数のシートから、繊維強化樹脂中間材22が形成される。
繊維強化樹脂中間材22に欠陥がないと判別されたときに(ステップS4、欠陥なし)、または、その繊維強化樹脂中間材22を修理した後に、さらに高温に加熱して樹脂を硬化させることにより、その繊維強化樹脂中間材22を繊維強化樹脂に形成する(ステップS6)。その繊維強化樹脂に欠陥がないかを検査し(ステップS7)、その繊維強化樹脂に欠陥が発見されないときに、繊維強化樹脂を完成させる。
また、注入用ツール35と同様にして、吸引用ツール32をバッグフィルム46に設置する。すなわち、バッグフィルム46のうちのパスメディア48が配置されている位置に吸引用孔を形成する。その吸引用孔の径は、吸引用ツール32の底面の径より若干小さい。両面テープを用いて、吸引用ツール32の多孔性板部56の周囲とバッグフィルム46に形成されたその吸引用孔の周囲とを接着する。次いで、シーラントを用いて、吸引用ツール32とバッグフィルム46との隙間から異物がモールド2の内部に侵入しないように、その隙間を封止する。さらに、吸引用管34を用いて吸引用ツール32と樹脂吸引装置33(図示せず)とを接続する。
