- the winding device may apply a single head or a multi head.
- the torch unit 323 may adopt a method of applying heat using a combustion gas method in order to reduce the size of the winding head 320.
- the torch unit 323 may adopt a method of using an electric heating element or a method of using a laser in addition to the method of using a combustion gas method, but the method of using an electric heating element or a laser increases the size of the head. There is a disadvantage.
- the flow rate of the combustion gas is controlled according to the linear velocity at which the carbon fiber-glass fiber hybrid roving is wound.
- the winding device for guiding the thermoplastic plastic-continuous fiber hybrid composite 305 supplied from the fiber supply member 310 between the fiber supply member 310 and the mandrel 330 to the mandrel 330 may further comprise a fiber conveying device.

- the carbon fiber-glass fiber hybrid roving in which these two hybrid composites 305a and 305b are mixed is tensioned by the tension unit 321 (S120), and then the carbon fiber-glass fiber hybrid roving is rotated. 510 (when there is no liner 510) is continuously wound at a constant speed along the outer circumferential surface of the mandrel 330 (S130).
- This hybrid winding process is freely moved in the desired direction, such as the X-axis direction, Y-axis direction, Z-axis direction, etc. with respect to the mandrel 330 using the winding head 320 that can be rotated more than nine axes as shown in FIG.
- the carbon fiber-glass fiber hybrid roving may be continuously wound on the liner 510.
- the X-axis winding is a longitudinal winding or a helical winding that winds the winding angle almost coincident with the rotational direction of the liner 510, and the Y-axis winding winds the winding angle substantially constant perpendicular to the axis. Circumferential winding (hoop winding).
- the winding angle may be adjusted according to the rotational speed of the liner 510 (the mandrel 330 if there is no liner 510) and the rotational or moving speed ratio of the winding head 320.
- the boss 515 is also wound by carbon fiber-glass fiber hybrid roving.
- the carbon fiber-glass fiber hybrid roving wound on the liner 510 (the mandrel 330 if there is no liner 510) is heated by the torch part 323 (S140) and then by the roll part 325. Squeezed and cooled (S150). Through this hot pressing process, the thermoplastic is melt-impregnated in the carbon fiber-glass fiber hybrid roving. This is because the carbon fiber-glass fiber hybrid roving is a unique material with a structure that can be sufficiently impregnated with proper heat and pressure.
- thermoplastic may be melt-impregnated in the carbon fiber-glass fiber hybrid roving.
- thermoplastic as a base material, unlike a thermosetting resin, a separate curing process is not required.

- the hybrid winding configuration is a horizontal configuration
- the two hybrid composites 305a and 305b are alternately wound with several layers stacked on different planes.
- one of the thermoplastic-carbon continuous fiber hybrid composite 305a is in contact with the liner 510, and one of the thermoplastic-glass continuous fiber hybrid composite 305b is exposed to the outside.
- the interface between these two hybrid composites 305a and 305b is maintained even after the thermoplastic plastic is melt-impregnated in the carbon fiber-glass fiber hybrid roving by hot pressing (or heat). Accordingly, as shown in FIG. 7, the glass fiber is impregnated with the first strength reinforcement layer 520a and the thermoplastic resin in which the thermoplastic composite in which the carbon fiber is impregnated in the thermoplastic plastic is formed on the outer circumferential surface of the liner 510.
- the high-pressure container 500 is formed of a thermoplastic composite material impregnated with carbon fibers and glass fibers in the thermoplastic plastics, including a strength reinforcing layer 520 formed by hybrid winding on the outer circumferential surface of the liner 510. And required properties It is easy to balance between them and can be recycled by using a thermoplastic resin.
- the hybrid winding configuration is a vertical configuration, it is more advantageous in terms of uniformity and content control of carbon fibers and glass fibers.
- the winding method of the present invention can achieve a balance between economical and demanded properties through controlling the content of carbon fiber and glass fiber in the production of moldings that do not require much weight reduction by using carbon fiber and glass fiber in a mixture.
- thermoplastic that does not require a curing process
- the hybrid winding method is applied to the manufacture of the high pressure vessel, it is possible to easily balance the economics and the required physical properties, it is possible to manufacture a high-pressure container that can be recycled with a reduction in production cost and productivity.
- the present invention has been described for convenience of description, the hybrid winding method of the thermoplastic plastic-continuous fiber hybrid composite of the present invention using the molding of the high-pressure container, but is not limited to this, various molding such as pipe or robot hand Of course, it can apply to manufacture of a base material.
