Metallic materials are used in many fields of engineering applications, but sometimes they are insufficient in terms of lightness. Therefore, in many studies, material types that will replace metallic materials are investigated and tendency towards composite materials is increasing. Composite materials are preferred in terms of both mechanical properties and lightness. Composite materials are produced in different ways. Generally, three different methods are used for composite materials. These are; hand lay-up method, filament winding and vacuum infusion method. Sometimes the shape of the composite material can be the reason that affects its production method. In cylindrical tube production, filament winding method is largely used. In our study, epoxy resin matrix fiber reinforced cylindrical tubes were tried to be produced by vacuum infusion method. It is stated how the difficulties encountered in the templates used in the production of composite circular tubes in vacuum infusion method were solved. Despite the wax applied to the metal templates, which has a separating function, the fiber and epoxy resin formed a whole with the metal and formed a hybrid composite material. In other words, the composite tube adhered to metal. No matter how much pressure was applied to the metal and fibers, they did not separate from each other. Even cutting the metal did not provide a solution. Dissolving by taking advantage of the temperature difference, namely expansion, has not been tried because it would create a second cure for composites. This has been tried to be overcome by using cardboard tubes. When choosing cardboard tubes, care has been taken to choose thick cardboards that will withstand the power of the vacuum infusion pump. The reason for choosing cardboard tubes is that cardboard has the ability to dissolve in water. As a result, the produced composites were thrown into water and the cardboard tube that dispersed in water was dissolved, leaving only the composite tube behind.
