た。In the manufacture of the conventional pressure vessel as described above, a large load due to the pressure difference between the inside and the outside of the mandrel is applied to the mandrel after the evacuation, so that the pressure resistance of the mandrel is reduced. Therefore, it is necessary to make the plate thickness of the mandrel sufficiently large, which causes a problem that the weight and cost of the mandrel increase.

As a result, the size of the mandrel is restricted. , This limits the size of the pressure vessel to be manufactured, and further, as the axial length increases, the radial deflection increases, and it is necessary to increase the plate thickness to keep the deflection amount constant. Since this also increases the weight of the mandrel, there is a problem in that the length is also restricted by this, and it has been a problem to solve these problems.

As a result, no pressure is applied to the mandrel 2 during evacuation, so the mandrel 2
Since it is not necessary to consider the pressure resistance in the thickness of the mandrel, the thickness of the mandrel 2 can be reduced, and the weight and cost of the mandrel 2 can be significantly reduced.

ドレルの重量やコストを大幅に低減することができる。As described above, according to the method of manufacturing a pressure vessel of the present invention, no pressure is applied to the mandrel during evacuation, so that the plate thickness of the mandrel can be significantly reduced. This makes it possible to significantly reduce the weight and cost of the mandrel.

制約についても緩和することができる。Further, since the vacuum is drawn between the first and second airtight sheets, the working time can be shortened as compared with the conventional case in which the entire inside of the airtight sheet and the mandrel is evacuated. Since the mandrel does not easily bend in the radial direction, it is easy to deal with the manufacture of a pressure vessel having a large axial length, and the restriction on the length can be relaxed.
