The FW method is a method in which continuous fibers impregnated with resin are wound around a mandrel (mold material), and then the resin is cured and then the mandrel is removed to manufacture hollow containers and pipes. Obtainable. This method has an advantage that a container having an arbitrary convex shape can be produced and the strength of a product obtained by changing the winding angle of the fiber can be adjusted. Conventionally, this FW
As a normal fiber winding method in the method, there are three methods as shown in FIG. (1) Helical (spiral) winding: This is a normal method for producing a pipe, in which a rotating mandrel is wound with fibers coming out of a yarn reciprocating in parallel with the rotating mandrel. The fiber shows a spiral trajectory in the cylindrical portion, and is wound in contact with the opening at the dome portions at both ends. In particular, if the dome curved surface is made to be an equal tension curved surface, the stress of the fiber on the dome can be made uniform with respect to the working internal pressure, and it is possible to wind the fiber with the minimum number of fibers in theory. Slip is likely to occur. The boss diameters at both ends must be the same in order to obtain an equal stress by using an equal tension curved surface.

る。(2) In-plane (planar) winding FIG. 2 shows the outline. This method is suitable for manufacturing a container having a relatively short shape such as a sphere, in which the mandrel shaft is rotated at a very low speed so that the mandrel shaft contacts the openings 12 and 13 of the large-diameter base dome portion 9 and the small-diameter base dome portion 10 at both ends. This is a method of winding the fiber 14 on a mandrel in a plane inclined with the axis. Since the winding surface of the fiber is wound in the longitudinal direction in the plane, the control mechanism is simplified, and slipping of the fiber hardly occurs. Although it is possible to wind even if the boss diameters of the openings at both ends are different, the stress of the fibers on the dome cannot be made uniform with respect to the working internal pressure.
In the case of in-plane winding, since the fiber direction is close to the axial direction, the strength of the cylindrical portion 8 in the circumferential direction is generally insufficient.
Need to be applied. (3) Circumferential winding When the reciprocating speed in the axial direction is extremely reduced using the same method as that for helical winding, the winding becomes substantially circumferential. Generally, when the fiber crossing angle of the cylindrical portion is small in the above winding methods (1) and (2), the circumferential winding is generally used for stacking on the cylindrical portion to reinforce it in the circumferential direction. Focusing on the circumferential portion, the stress state at the time of the internal pressure action is circumferential stress: axial stress = 2: 1. Therefore, if only the cylindrical portion is limited, the fiber with the minimum fiber amount and the maximum withstand pressure can be obtained. The winding angle can be determined theoretically and is found to be 55 °.

で補強する必要があり、軸方向繊維が過剰となる。[0004] Since the diameter of the opening at both ends of a cylindrical internal pressure vessel is generally different, in the case of producing a pressure vessel by a conventional production method, it is inevitable to use in-plane winding. However, this method has a problem that the total fiber amount increases and the weight increases for the following reasons. As described above, in the in-plane winding, the fiber tension of the dome portion at the time of the internal pressure action is not constant, so that a high stress portion and a low stress portion are formed, so that the fiber amount becomes excessive in the low stress portion. As described above, in the in-plane winding, the fiber is wound so as to be in contact with the caps at both ends, so that the longer the container, the smaller the crossing angle of the fiber, and near the circumference of the dome, the strength in the circumferential direction against internal pressure is insufficient. It is necessary to reinforce by directional winding, and the axial fiber becomes excessive. For the same reason, it is necessary to reinforce the cylindrical portion by winding in the circumferential direction for the same reason, and the axial fiber becomes excessive.

ものである。SUMMARY OF THE INVENTION The present invention is a cylindrical pressure vessel made of FRP having domes at both ends manufactured by a filament winding method, wherein the domes have opening radii of r 1 and r 2 respectively.

-1 (r 1 / r) and β = sin -1 (r 2 / r), and in the cylindrical portion, the fiber winding angle is substantially 55 ° so that the weight is theoretically the minimum with respect to the internal pressure. A filament-shaped pressure vessel with a dome made of FRP, characterized in that after the filament is wound in such a manner as described above, the angle change region generated at the transition portion from the cylindrical portion to the dome portion is subjected to cylindrical winding and reinforced, thereby forming a cylindrical pressure vessel with a dome made of FRP. . The fiber winding angle in the dome portion and the cylindrical portion allows an error of about ± 1 °.

In addition, since the strength difference between the fiber and the plastic constituting the FRP is large, the equal tension curved surface is regarded as a surface that assumes that only the fiber bears the strength and that the tension of the fiber becomes equal over the entire surface when an internal pressure is applied. . And the angle of the helical winding is r
1 and r 2 , the radius of the dome at any position is r
In this case, the winding angle of the filament around the mandrel is set to α = sin −1 (r 1 / r) and β = sin −1 (r 2 / r) in the dome portion. That is, assuming that the diameter of the cylindrical portion is r 0 , the fiber winding angle at the dome portion is sin −1 (r 1 / r 0 ) or sin −1 (r 2 /

In addition, as described above, the fiber winding angle in the dome portion and the cylindrical portion does not need to be exactly the above angle, and is ± 1 °.
It should just be in the range of the degree.

Since the book fibers are wound and formed, a winding angle changing area is provided between the dome portion and the cylindrical portion. In this angle change region, the fiber winding angle is not under the optimum condition with respect to the working internal pressure, so that this portion is further reinforced by circumferential winding.

In the angle changing region, the strength against the working internal pressure is insufficient, so that reinforcement is performed by circumferential winding as in the related art. However, since the range in which the strength is insufficient is limited only to the angle changing region, the reinforcement is required. Fewer fibers required.
