Definitions
- a tank used for storing hydrogen or the like a tank having an FRP layer in which hoop layers and helical layers are alternately stacked on the outer periphery of a liner is used (see, for example, Patent Document 1).
- the hoop layer is a layer formed by hoop-wrapping a bundle of fibers (for example, carbon fibers) (how to wind the tank body portion substantially perpendicularly to the tank axis), and the helical layer is made of CF (carbon fiber) or the like.
- the fiber bundle is a layer formed by helical winding (which is substantially parallel to the tank axis and wound to the tank dome) (see FIG. 2 of the present application).
- the fatigue strength of the layer adjacent to the outer side is reduced due to the step of the surface of the helical layer located in the inner layer of the FRP layer, particularly the innermost helical layer. There is a problem of lowering.
- the present invention has made it possible to avoid the phenomenon that the fatigue strength of the layer adjacent to the outside (particularly the hoop layer) is reduced due to the step difference of the surface of the helical layer located in the inner layer in the FRP layer. It is an object of the present invention to provide a tank having a structure and a manufacturing method thereof.
- the present inventor has made various studies and found that the fatigue strength in the hoop layer is reduced when the structural bending of the fiber bundle of the hoop layer is large. That is, when the FRP layer is formed by stacking the hoop layer and the helical layer, if the helical layer itself adjacent to the hoop layer has irregularities, the irregularities are transferred to the adjacent hoop layer, thereby The fiber bundle of the layer itself meanders to cause undulations, and bending (undulations) due to the structure occurs in the hoop layer.
- the present invention is based on such knowledge, and is a tank having a liner, and an FRP layer composed of a hoop layer and a helical layer that are alternately formed by winding a fiber bundle around the outer periphery of the liner, the FRP layer In at least one of the plurality of helical layers located in the inner layer, the cross-sectional area of the fiber bundle constituting the helical layer is equal to the cross-sectional area of the fiber bundle constituting the other layer formed outside the helical layer. Is smaller than that.
- the helical layer is wound so as to be substantially parallel to the tank axis and folded back at the tank dome (see FIG. 2), so as to eliminate a gap between adjacent fiber bundles. Since winding is not specifically considered, it is fundamentally difficult. In general, the helical layer is wound in a disorderly manner without considering the overlapping and arrangement of fiber bundles, and conventionally, for example, the phase of the reinforcing fiber bundles of each helical layer is shifted in the circumferential direction of the cylinder.
- the cross-sectional area of the fiber bundle constituting the helical layer is set to the other layer formed outside the helical layer.
- the unevenness in the helical layer is reduced. That is, when a helical layer is formed using a fiber bundle having a small cross-sectional area in this way, the thickness of the fiber bundle is reduced to that extent, and the height of the fiber bundle is lowered accordingly. Moreover, the gap between the fiber bundles is also reduced.
- a conventional helical layer (referred to as a helical layer that has not been subjected to a smoothing process and has irregularities on its surface, indicated by reference numeral 70B in FIGS. 11 and 12). It is possible to reduce the bending of the structural fiber bundle as described above. Therefore, by suppressing the structural bending (undulation) of the fiber bundle of the layer (for example, the hoop layer) formed outside the helical layer, The fatigue strength of the fiber bundle itself can be improved. It is also possible to improve the burst strength by reducing the thickness of the helical layer and the layer (for example, the hoop layer) formed outside the helical layer and increasing the Vf (fiber volume content).
- the helical layer located in the inner layer is preferably the innermost helical layer.
- the fiber bundle layer (helical layer, hoop layer) has a greater contribution to the tank strength as the inner layer (layer closer to the liner).
- the innermost helical layer is constituted by a fiber bundle having a small cross-sectional area as in the present invention
- the layer adjacent to the outer side of the innermost helical layer is wound more smoothly. Therefore, the structural bending (undulation) of the fiber bundle of the layer can be suppressed and the tank strength can be improved.
- the cross-sectional area of the fiber bundle is preferably changed by changing the number of fibers constituting the fiber bundle. In the case where a plurality of fibers are bundled to form a fiber bundle, if the number of fibers is reduced, the cross-sectional area of the fiber bundle can be reduced accordingly.
- the thickness of the fiber bundle in the stacking direction of the FRP layer is reduced by increasing the tension with respect to the fiber bundle constituting the helical layer. If the thickness of the fiber bundle is reduced and flattened, the unevenness in the helical layer is reduced accordingly, and the unevenness is transferred to another layer (for example, a hoop layer) formed outside the helical layer. It becomes possible to suppress.
- a fiber bundle composed of a fiber bundle having a diameter larger than that of the fiber bundle constituting the other layers as the fiber bundle constituting the other layer formed outside the helical layer.
- the manufacturing method according to the present invention is a method for manufacturing a tank having a liner and an FRP layer composed of a hoop layer and a helical layer that are alternately formed by winding a fiber bundle around the outer periphery of the liner.
- a cylinder according to the present invention is a cylinder having an FPR layer composed of hoop layers and helical layers alternately formed by winding a fiber bundle, and a plurality of helical layers located in an inner layer of the FRP layer
- the cross-sectional area of the fiber bundle constituting the helical layer is smaller than the cross-sectional area of the fiber bundle constituting the other layer formed outside the helical layer.
- the present invention it is possible to avoid the phenomenon that the fatigue strength of the layer adjacent to the outside (particularly the hoop layer) is reduced due to the step difference of the surface of the helical layer located in the inner layer in the FRP layer. Become.
- FIG. 1 to 4 show an embodiment of a tank and a manufacturing method thereof according to the present invention.
- the tank (henceforth a high pressure tank) 1 concerning this invention is applied to the high pressure hydrogen tank as a hydrogen fuel supply source.
- the hydrogen tank can be used in a fuel cell system or the like.
- the high-pressure tank 1 has, for example, a cylindrical tank body 10 having both ends substantially hemispherical, and a base 11 attached to one end of the tank body 10 in the longitudinal direction.
- the substantially hemispherical portion is referred to as a dome portion
- the cylindrical body portion is referred to as a straight portion, which are denoted by reference numerals 1d and 1s, respectively (see FIGS. 1 and 2).
- the high pressure tank 1 shown by this embodiment has the nozzle
- the tank body 10 has, for example, a two-layer wall layer, and has a liner 20 that is an inner wall layer and, for example, an FRP layer 21 that is a resin fiber layer (reinforcing layer) that is an outer wall layer on the outer side.
- the FRP layer 21 is formed of, for example, only the CFRP layer 21c, or the CFRP layer 21c and the GFRP layer 21g (see FIG. 1).
- the liner 20 is formed in substantially the same shape as the tank body 10.
- the liner 20 is made of, for example, polyethylene resin, polypropylene resin, or other hard resin.
- the liner 20 may be a metal liner formed of aluminum or the like.
- a folded portion 30 that is bent inward is formed on the tip end side of the liner 20 having the base 11.
- the folded portion 30 is folded toward the inside of the tank body 10 so as to be separated from the outer FRP layer 21.
- the folded portion 30 has, for example, a reduced diameter portion 30a that gradually decreases in diameter as it approaches the folded tip, and a cylindrical portion 30b that is connected to the distal end of the reduced diameter portion 30a and has a constant diameter.
- the cylindrical portion 30b forms an opening of the liner 20.

- the bending angle can be reduced to about 4.2 to 5.5 ° only by increasing the diameter of the fiber bundle 70 (see FIG. 9). That is, when the wire diameter of the fiber bundle 70 of the hoop layer 70P is increased in this way, the rigidity per fiber decreases, so that even when the same force is applied, the bending angle is reduced and the bending angle is reduced.
- the FW device 80 shown in FIGS. 13 and 14 reciprocates a guide device (referred to as an “eye opening”) 81 of the fiber bundle 70 along the tank axis direction while rotating the liner 20 around the tank axis.
