Filament winding device and filament winding method

The present invention relates to a filament winding apparatus and a filament winding method, and more particularly, through a resin selection part during a continuous process to impregnate different types of resins with each other according to the direction or length of the fibers wound on the liner. By selecting any one of the resin supply parts in which the resin is accommodated and manufacturing the pressure vessel by widing the fibers impregnated with resins with different elongation, rigidity and heat resistance, heat resistance and rigidity are improved while preventing cracks in the pressure vessel containing high-pressure gas.

There are several methods for molding a composite material. Examples of molding methods for a composite material based on a polymer material include an autoclave molding method, a vacuum bag molding method, a compression molding method, and a filament molding method. Winding (Filament Winding), SMC molding method (Sheet Molding Compound) or BMC molding method (Bulk Molding Compound), RTM molding method (Resin Transfer Molding), pultrusion molding method, hot press molding method, etc. are available. Among these methods, the filament winding molding method is mainly used for manufacturing circular products.

The filament winding method is a composite molding method in which continuous fibers impregnated with resin are wound around a cylindrical rotating mandrel and cured to produce a rotationally symmetrical structure. It is possible to apply the wet winding method, which is impregnated while passing through the resin bath, and the dry winding method using tow prepreg.

Recently, the development of hydrogen fuel cell vehicles as a next-generation transportation means has been activated, and hydrogen fuel cell vehicles are eco-friendly vehicles that operate by driving a motor using electricity obtained by reacting hydrogen with oxygen in the air instead of a gasoline internal combustion engine.

Since hydrogen fuel cell vehicles emit almost no pollutants, environmental pollution is low, and long-distance driving is possible even with a small amount of fuel.

However, there is a possibility that hydrogen may explode in case of a severe vehicle accident, and the economic feasibility is pointed out as a disadvantage due to high energy consumption in generating hydrogen.

Electricity generation, the core of a hydrogen fuel cell vehicle, drives the motor with electricity generated by the reaction of hydrogen and oxygen through a catalyst.

That is, when water is electrolyzed, oxygen is generated at the positive (+) electrode and hydrogen is generated at the negative (-) electrode.

Among the methods of storing hydrogen, which is the core of such a hydrogen fuel cell vehicle, the most efficient method is to store hydrogen at high pressure in a hydrogen tank.

This is a method of supplying hydrogen using a compressed hydrogen tank/liquid hydrogen tank, and it is completely pollution-free as only water is generated during operation. However, the disadvantages include increased vehicle volume due to tank mounting, instability of hydrogen, and difficulty in building hydrogen supply infrastructure.

A pressure vessel for storing high-pressure gas basically requires a material that is strong and can withstand high pressure. In particular, in the case of a pressure vessel used in automobiles, it is essential to reduce the weight of the structure in order to improve fuel efficiency and performance of automobiles.

Therefore, the application of light and strong carbon fiber composite material is an effective solution to replace the metal pressure vessel. Composite material pressure vessels such as hydrogen tanks and compressed natural gas (CNG) tanks are generally manufactured using the filament winding method, which is manufactured by impregnating carbon fiber with epoxy resin and then winding it on a plastic liner. This is because a structure having a cylindrical shape or a curvature can be easily manufactured by integral molding.

In addition, the hydrogen tank has a charging pressure of 350 bar or 700 bar, and in order to prevent accidents due to hydrogen instability, it is regulated to verify stability at 1.5 times the pressure during container manufacturing.

1 and 2, the types of methods for winding the resin-impregnated fiber on the plastic liner to manufacture a pressure vessel such as a hydrogen tank are Hoop Wrapped (Vertical Winding) and Helical Wrapped. Spiral winding), Hoop Wrapped (vertical winding) is used as a method to increase elongation, and Helical Wrapped (helical winding) is used for strength.

Referring to FIG. 3 , the pressure vessel manufactured by the conventional filament winding device and the filament winding method is manufactured by winding the plastic liner using a fiber impregnated with a single resin having the same elongation. When gas is filled in a container or a pressure test is performed, the gas container expands. In this case, the degree of expansion is different between the cylinder direction (A direction) and the circumferential direction (B direction) of the pressure vessel, so the cylinder with a relatively large degree of expansion In the direction (B direction), cracks (C) were generated, and there was a problem in that the performance and stability of the pressure vessel were deteriorated.

In addition, in the pressure vessel manufactured by the conventional filament winding device and the filament winding method, the gas vessel is expanded in the process of filling the manufactured pressure vessel with gas or performing a pressure resistance test, so that a crack is generated in the circumferential direction (B direction). Because the pressure vessel is used by the operator or the driver of a hydrogen fuel cell vehicle in the state in which it occurs, it causes inconvenience to the experimenter conducting the pressure test due to the explosion of hydrogen gas, etc., which has a very high explosive power, and causes accidents on property, such as automobiles, or personal accidents. There was a problem that the risk of a safety accident was very high.

Besides. The pressure vessel manufactured by the conventional filament winding device and filament winding method is frequently damaged during gas filling or pressure resistance test, and has low durability. There is a problem of delaying time, and when it is installed and used in a vehicle, there is a problem in that the maintenance cost of the vehicle is greatly increased, such as having to replace the pressure vessel or the vehicle itself for stability.

For example, when it is necessary to apply more tension to the fibers 2 impregnated with the resins 4 and 5, the sub-regulating unit 2222 is raised and lowered so that the resins 4 and 5 are interposed between the main adjusting units 2221. By pulling the impregnated fiber (2) stronger, the resin (4, 5) is impregnated with the fiber (2), and on the contrary, the tension is reduced to the fiber (2) impregnated with the resin (4, 5). In this case, the sub-regulating unit 2222 descends to weakly release the force pulling the fibers 2 impregnated with the resins 4 and 5 between the main adjusting units 2221, so that the resins 4 and 5 are impregnated.

The injection unit 2000 of the filament winding device 1 according to the present invention is characterized in that different types of resins 4 and 5 are crossed and impregnated according to the direction or length of the fiber 2 wound on the liner 3 . do it with

One of the resins used when manufacturing pressure vessels such as hydrogen tanks and compressed natural gas (CNG) tanks through the filament winding device is an epoxy resin.

This is because epoxy resin has excellent mechanical properties, heat resistance and chemical resistance, so it is suitable for pressure vessels where safety certification is essential. In addition, as another type of resin, urethane resin has excellent elongation and chemical resistance but has low heat resistance, and phenolic resin has high chemical resistance and heat resistance, but high viscosity is not suitable for wet winding process.

The filament winding device 1 according to the present invention includes the resin 4 accommodated in the bath 2341 of the first resin supply 2310 and the resin 5 accommodated in the bath 2341 of the second resin supply 2320. is formed of different types of resins.

Specifically, the resin 4 accommodated in the bath part 2341 of the first resin supply part 2310 uses a high elongation resin, and the resin 5 accommodated in the bath part 2341 of the second resin supply part 2320 has the elongation. Use this low resin. Or on the contrary, the resin 4 accommodated in the bath 2341 of the first resin supply 2310 uses a low elongation resin, and the resin 5 accommodated in the bath 2341 of the second resin supply 2320 is Uses high elongation resin

Elongation refers to the rate at which the material elongates during a material tensile test. In the present invention, by using two types of resins, one with high elongation and one with low elongation, when hydrogen is filled in the pressure vessel, the vessel expands and In order to prevent cracks from occurring in the circumferential direction, a fiber impregnated with a high elongation resin is used for winding, and a fiber impregnated with a low elongation resin is used to maintain the high rigidity of the pressure vessel filled with high-pressure gas. It is wound on the liner by crossing it with the fiber impregnated with high elongation resin.

A resin with a high elongation has a high elongation rate, which has the advantage of being stretched flexibly in the expansion of a pressure vessel, but a resin with a high elongation has a problem with insufficient heat resistance due to a low Tg value.

Conversely, resins with low elongation have advantages in heat resistance and high rigidity. Due to the low elongation ability, there is a problem that cracks occur in the pressure vessel due to expansion of the pressure vessel.

Therefore, in the filament winding device 1 according to the present invention, the resin 4 accommodated in the bath portion 2341 of the first resin supply unit 2310 uses a high elongation resin, and the bath portion of the second resin supply unit 2320 ( The resin 5 accommodated in 2341 uses a resin having a low elongation, or on the contrary, the resin 4 accommodated in the bath 2341 of the first resin supply part 2310 uses a low elongation resin, and the second resin supply part ( The resin 5 accommodated in the bath portion 2341 of 2320 is used to cross with a resin with a low elongation by using a resin with a high elongation, so that both heat resistance and elongation can be supplemented.

The resin having a low elongation, which is any one of the heterogeneous resins 4 and 5 accommodated in the bath 2341 of the resin supply unit 2300 of the filament winding device 1 according to the present invention, has an elongation of 1% or more to 3 % or less, and the high elongation resin, which is another one of the heterogeneous resins (4, 5), may have an elongation of 5% or more to 10% or less,

If the elongation of the resin with a low elongation, which is one of the heterogeneous resins 4 and 5, is less than 1%, the degree of fiber elongation is too small to be broken by the tension applied to the fiber during the winding process of the fiber during the winding process. If the elongation exceeds 3%, the heat resistance is too low to comply with the verification items of the pressure vessel, and there is a problem in that the rigidity is too low, causing a risk of explosion such as hydrogen in the pressure vessel.

In addition, if the elongation of the resin having a high elongation, which is any other of the heterogeneous resins 4 and 5, is less than 5%, the degree of fiber elongation is too small, so that the filament winding device and the gas in the pressure vessel manufactured by the filament winding method When filling or performing a pressure test, the gas container expands. In this case, the degree of expansion is different between the cylinder direction (A direction) and the circumferential direction (B direction) of the pressure vessel, and the degree of expansion is relatively large in the circumferential direction (B). direction), the fibers cannot be stretched to correspond to the degree of expansion, and cracks (C) are generated in the circumferential direction (B direction) of the pressure vessel, resulting in a problem that the performance and stability of the pressure vessel are deteriorated.

In addition, when the elongation exceeds 10%, the fiber is too swamped to wind the liner 3 and the force to press the liner against the tension of the fiber is too low, so the stiffness of the compression container in which the compressed gas is accommodated is too high. It is low and not only does not comply with the verification items of the pressure vessel, but also has a problem that there is a risk of explosion such as hydrogen in the pressure vessel because the stiffness is too low.

As described above, the low elongation resin, which is any one of the heterogeneous resins 4 and 5 accommodated in the bath 2341 of the resin supply unit 2300, has an elongation of 1% or more to 3% or less, The other high elongation resin among the resins 4 and 5 has an elongation of 5% or more to 10% or less, and when two types of resins of high elongation and low elongation are used interchangeably by a resin selection part to be described later. When a pressure vessel is filled with hydrogen by winding using a fiber impregnated with a high elongation resin, the vessel expands to prevent cracks from occurring in the circumferential direction of the pressure vessel, and a fiber impregnated with a low elongation resin is used. Thus, by winding the gyoza to maintain the high rigidity of the pressure vessel itself, which is filled with high-pressure gas, the stability of the pressure vessel itself is increased to perform pressure resistance tests, or human accidents including workers charging gas or drivers of hydrogen fuel cell vehicles, etc. Accidents can be prevented.

Filament winding device 1 according to the present invention is a resin with a high elongation or a resin with a low elongation according to the direction or length of the fiber 2 wound on the liner 3, the different types of resins 4 and 5 to each other. cross and impregnate.

As an example with reference to FIG. 5 , when the direction of the fiber 2 wound on the liner 3 is Hoop Wrapped (vertical winding), the tip of the arm 4300 of the carriage unit 4000 is As the winding part 4400 is positioned in the height direction, a Hoop Wrapped (vertical winding) is performed as shown in FIG. 1 . The Hoop Wrapped (vertical winding) is used as a method to increase the elongation. In this case Winding should be done using the fiber (2) impregnated with a high elongation resin.

If the high elongation resin 4 is accommodated in the first resin supply unit 2310 and the low elongation resin 5 is accommodated in the second resin supply unit 2320, the upper portion of the first resin supply unit 2310 is accommodated. The rod part 2413 of the cylinder part 2412 that is installed opposite to the is drawn out, and the rod part 2413 is drawn out adjacent to the first resin supply part 2310 and the fiber sandwiched between the rolling parts 2414. (2) Also, the fibers 2 move in a direction adjacent to the first resin supply unit 2310 so that the fibers 2 come into contact with the drum unit 2341 of the first resin supply unit 2310, so that the elongation received in the first resin supply unit 2310 is As the high resin 4 moves on the drum 2341 and comes into contact with the fibers 2 , the resin 4 with high elongation is impregnated into the fibers 2 .

In addition, at the same time, the drum part 2341 of the second resin supply part 2320 in which the resin 5 with a low elongation is accommodated and the fiber 2 should not come into contact with the upper part of the second resin supply part 2320. The rod part 2413 of the installed cylinder part 2412 is drawn in, and the rod part 2413 is drawn away from the second resin supply part 2320, and the fiber 2 sandwiched between the rolling parts 2414. In addition, by moving in a direction away from the second resin supply unit 2320 so that the fibers 2 do not come into contact with the drum unit 2341 of the second resin supply unit 2320, the resin with a low elongation received in the second resin supply unit 2320. (5) prevents the fiber (2) from being impregnated.

Referring to FIG. 6, an example of the opposite case to that of FIG. 5 will be described. When the direction of the fiber 2 wound on the liner 3 is helical wrapped as shown in FIG. 2, the carriage unit ( When the winding part 4400 at the tip of the arm part 4300 of 4000) is not located in the height direction, but is rotated and tilted, as shown in FIG. 2, a helical wrapped (helical winding) is performed. Helical Wrapped (helical winding) is used to increase strength, and in this case, it must be wound using a fiber (2) impregnated with a resin with a low elongation.

If a high elongation resin 4 is accommodated in the first resin supply unit 2310 and a low elongation resin 5 is accommodated in the second resin supply unit 2320, the upper portion of the second resin supply unit 2320 is accommodated. The rod part 2413 of the cylinder part 2412 that is installed opposite to the is drawn out, and the rod part 2413 is drawn out adjacent to the second resin supply part 2320 and the fiber sandwiched between the rolling parts 2414. (2) Also, the fibers 2 move in a direction adjacent to the second resin supply unit 2320 so that the fibers 2 come into contact with the drum unit 2341 of the second resin supply unit 2320, so that the elongation accommodated in the second resin supply unit 2320. As the low resin 5 moves along the drum 2341 and comes into contact with the fibers 2, the resin 5 with a low elongation is impregnated into the fibers 2 .

In addition, at the same time, the drum unit 2341 of the first resin supply unit 2310 in which the resin 4 having a high elongation is accommodated and the fiber 2 should not come into contact with the upper portion of the first resin supply unit 2310 so as to face the upper part of the first resin supply unit 2310. The rod part 2413 of the installed cylinder part 2412 is drawn in, and the rod part 2413 is drawn away from the first resin supply part 2310, and the fiber 2 sandwiched between the rolling parts 2414. In addition, by moving in a direction away from the first resin supply unit 2310 so that the fibers 2 do not come into contact with the drum unit 2341 of the first resin supply unit 2310, the resin with high elongation accommodated in the first resin supply unit 2310 (4) prevents the fiber (2) from being impregnated.

In addition, the filament winding apparatus according to the present invention can perform the above-described operation according to the length of the fiber 2 wound on the liner 3 , for example, the length of the fiber 2 wound on the liner 3 . When is less than a certain length, the operation as shown in Fig. 5 is implemented, and thereafter, in a manner that implements the operation as shown in Fig. 6, different types of resins (4, 5), which are resins with high elongation or low elongation, are crossed with each other to form fibers (2) can be impregnated.

As such, the filament winding device according to the invention is used to fill a gas or perform a pressure test as a pressure vessel is produced through fibers impregnated with resins having different elongations depending on the direction of the fiber wound on the liner or the length of the fiber. In the process, in order to increase the elongation in the circumferential direction (B direction), where the degree of expansion is relatively large, in the circumferential direction (B direction), the fiber is wound through a fiber impregnated with a high elongation resin to prevent cracks in the pressure vessel. It is possible to increase the durability and stability of the pressure vessel by preventing the occurrence of cracks (C) in the circumferential direction (B direction) due to expansion of the gas vessel in the process of filling gas or performing a pressure resistance test. Because it is prevented in advance, hydrogen, etc., which have very high explosive power, are safely stored to cause property accidents such as explosions of automobiles, etc. in which pressure vessels are stored, or personal accidents, including workers who perform pressure tests or charge gas, or drivers of hydrogen fuel cell vehicles, etc. Accidents can be prevented.

The resin selection unit 2400 according to the present invention includes a bath moving unit 2420 . It includes a base moving part 2420 , a support part 2421 , a housing part 2422 , an elevating part 2423 , and a detection part 2424 .

The support part 2421 is installed adjacent to the resin supply part 2300 and serves to support the resin supply part. The support part 2421 may be installed to face the support part 2411 in a height direction and spaced apart from each other.

The housing part 2422 may be formed in plurality, and each housing part 2422 is installed between the lower part of the first resin supply part and the upper part of the support part 2421 , and the lower part of the second resin supply part and the support part 2421 . ) is installed between the upper part of the

The elevating part 2423 is installed in the housing part 2422 to be retractable or withdrawable.

The detection unit 2424 is installed in the housing unit 2422 to detect the operation of the bath moving unit 2420 .

The base moving part 2420 accommodates different kinds of resins in the first resin supply part and the second resin supply part to cross and impregnate different kinds of resins with each other according to the direction or length of the fibers wound on the liner, and the liner When the elevating unit adjacent to the first resin supply unit is drawn in (lowered) according to the direction or length of the fiber to be wound, the elevating unit adjacent to the second resin supply unit is drawn out (elevated), and adjacent to the first resin supply unit When the elevating unit is withdrawn, the elevating unit adjacent to the second resin supply unit is drawn in.

Referring to FIG. 7 as an example, as in FIG. 5 , when the direction of the fiber 2 wound on the liner 3 is Hoop Wrapped (vertical winding), the arm portion 4300 of the carriage unit 4000 ), the winding part 4400 is positioned in the height direction, and as shown in FIG. 1 , a hoop wrapped (vertical winding) is performed. The hoop wrapped (vertical winding) is used as a method to increase the elongation. In this case, the winding should be performed using the fiber (2) impregnated with a resin having a high elongation.

In this case, as described above, the fiber moving unit 2410 operates, and simultaneously with the operation of the fiber moving unit 2410, the base moving unit 2420 also operates.

If a high elongation resin 4 is accommodated in the first resin supply unit 2310 and a low elongation resin 5 is accommodated in the second resin supply unit 2320, the lower portion of the first resin supply unit 2310 is The elevating part 2423 of the housing part installed in the is drawn out (raised) and pushed while pressing the first resin supply part 2310, so that the first resin supply part 2310 is raised so as to be adjacent to the fiber 2 .

Accordingly, when the fiber comes into contact with the drum unit 2341 of the first resin supply unit 2310, the high elongation resin 4 accommodated in the first resin supply unit 2310 moves along the drum unit 2341 and moves to the fiber 2 ) and the resin 4 having a high elongation is impregnated into the fiber 2 as they come into contact with each other.

In addition, at the same time, the drum unit 2341 of the second resin supply unit 2320 in which the resin 5 having a low elongation is accommodated and the fiber 2 should not come into contact with the housing installed under the second resin supply unit 2320 . The negative elevating unit 2423 enters (falls down) so that the second resin supply unit 2320 descends away from the fiber 2 while descending.

Accordingly, the resin 5 having a low elongation received in the second resin supply unit 2320 is prevented from being impregnated into the fiber 2 by preventing the fiber from contacting the drum unit 2341 of the second resin supply unit 2320 .

Referring to FIG. 8, an example of the opposite case to FIG. 7 will be described. When the direction of the fiber 2 wound on the liner 3 is helical wrapped as shown in FIG. 2, the carriage unit ( When the winding part 4400 at the tip of the arm part 4300 of 4000) is not located in the height direction, but is rotated and tilted, as shown in FIG. 2, a helical wrapped (helical winding) is performed. Helical Wrapped (helical winding) is used to increase strength, and in this case, it must be wound using a fiber (2) impregnated with a resin with a low elongation. Accordingly, the operation is reversed to the case of FIG. 7 described above.

In addition, the filament winding apparatus according to the present invention can perform the above-described operation according to the length of the fiber 2 wound on the liner 3,

For example, if the length of the fiber 2 wound on the liner 3 is less than a certain length, the operation as shown in FIG. 7 is implemented, and after that, the resin with high elongation or the elongation is obtained by implementing the operation as shown in FIG. 8 . It is possible to impregnate the fibers 2 by crossing different resins 4 and 5, which are low resins.

As such, in the filament winding device according to the invention, the method of intersecting and impregnating resins having different elongations depending on the direction of the fiber wound on the liner or the length of the fiber is realized by the operation of the base moving part as well as the above-described fiber moving part. At the same time as the fiber descends by the eastern part, the bath part goes up and down by the bath moving part, and in the opposite case, the opposite operation is implemented at the same time, so that the drum part and the fiber with the resin selected from different types of resin are in contact with each other easily and precisely. Filament winding operation by impregnating with resin and not impregnating the rest of the resin so that it is impregnated with resins with different elongations according to the direction of the fiber wound on the liner or the length of the fiber more quickly, accurately and precisely. time can be minimized.

In addition, the filament winding device according to the invention provides a method of intersecting and impregnating resins having different elongations depending on the direction of the fiber wound on the liner or the length of the fiber. It is realized by the operation of the bath moving part where the bath only moves regardless, so that the fiber is subjected to tension due to the excessive operation of the fiber moving part during the process of winding the fiber to minimize damage to the fiber, and the fiber's tension is frequently changed so that the fiber It is possible to increase the durability and stability of the pressure vessel by preventing the production of defective pressure vessels because the impregnation rate to be impregnated according to the change of the tension of the pressure vessel is not uniform.
