MANUFACTURING METHOD OF COMPOSITE MATERIAL TUBE AND MANUFACTURING DEVICE THEREOF

PROBLEM TO BE SOLVED: To provide a manufacturing method and a manufacturing device of a composite material tube, by which a structure of a composite material tube can be made consistent and a molding effect can be improved.SOLUTION: A manufacturing device of a composite material tube includes: a first metal mold that has a first molding surface on its outer periphery surface, a first contact end at its one end, and a first limiting end on the other end and has a diameter of the first limiting end larger than a diameter of the first contact end; a second metal mold that has a second molding surface on its outer periphery surface, a second contact end at its one end and a second limiting end at the other end and has a diameter of the second limiting end larger than a diameter of the second contact end, pushes the second contact end against the first contact end and makes the second molding surface contact with the first molding surface to form a molding surface; and a vacuum bag film that is located outside of the first metal mold and the second metal mold, forms a seal space between the first metal mold and the second metal mold, and is connected to a vacuum pump that is communicated with the seal space.SELECTED DRAWING: Figure 6 【課題】複合材料チューブの構造を堅実にすることが可能であり、成形効果が良くなる複合材料チューブの作製方法とその装置を提供する。【解決手段】その外周面に第１型面を有し、その一端に第１当接端を有し、その他端に第１規制端を有し、第１規制端の直径は第１当接端の直径より大きい第１金型と、その外周面に第２型面を有し、その一端に第２当接端を有し、その他端に第２規制端を有し、第２規制端の直径は第２当接端の直径より大きく、第２当接端は第１当接端に押付け、第２型面は第１型面に当接して成形面を形成する第２金型と、第１金型と第２金型との外側に位置し、第１金型及び第２金型との間に封止空間が形成され、真空ポンプに接続されており、真空ポンプは封止空間と連通する真空袋フィルムと、を含む。【選択図】図６
