Field of the Invention The present invention relates to a disk-shaped rotating body made of a fiber-reinforced composite material, and more particularly, a fiber-reinforced composite material rotating body suitable as a flywheel for energy storage that rotates at a high speed, and a method for producing the same. It is about.

れている。2. Description of the Related Art A flywheel is a system for accumulating rotational energy by rotating a disc at a very high speed.
It is used as a rotating body of a wheel energy storage system), and in order to make this rotating body compact, it is necessary to select a material that can withstand a high peripheral speed. At that time, high specific strength (strength / specific amount) is a criterion for material selection. Therefore, particularly in the case of a large flywheel, fiber-reinforced composite materials such as high-strength carbon fiber plastics are drawing attention.

異方性が大きく、また繊維の配向方向である円周方向の
強度は非常に大きいが、半径方向の強度は繊維と直交す
る方向であるので極端に小さい。As the rotating body made of this fiber-reinforced composite material,
For example, filament winding
A method has been proposed in which reinforcing fibers impregnated with a resin are wound in the circumferential direction by molding by the method. However, this rotor has large anisotropy and the strength in the circumferential direction, which is the orientation direction of the fibers, is very large, but the strength in the radial direction is extremely small because it is in the direction orthogonal to the fibers.

クが生じる。また残留応力が大きくない場合でも、回転
時の遠心力によって生じる半径方向の応力と重畳して、
比較的低い回転数で周方向に沿ってクラックが生じ、回
転体が破損しやすい。For this reason, cracks are generated in the circumferential direction due to residual tensile stress in the radial direction that occurs during hardening during the molding process of the rotating body. Even if the residual stress is not large, it will overlap with the radial stress caused by the centrifugal force during rotation,
Cracks are generated along the circumferential direction at a relatively low rotation speed, and the rotating body is easily damaged.

A rotating body in which fibers are oriented in the radial direction has also been proposed. FIG. 4 is an exploded perspective view showing the structure of a conventional rotating body disclosed in, for example, Japanese Patent Laid-Open No. 61-31739. FIG. 5 is a perspective view showing the outer shape of the rotating body. In the figure, 1 is a disk-shaped rotating body, in which the reinforcing fibers 2 are oriented in the circumferential direction, and the circumferential reinforcing layer 4 made of a fiber-reinforced composite material combined with the matrix material 3 and the reinforcing fibers 2 are in the radial direction. And the radial direction reinforcing layers 5 made of a fiber-reinforced composite material which is orientated to the matrix material 3 are alternately laminated and integrated.

き、例えば半径方向強化層の外径が内径の１０倍あると
すると、外径側と内径側の繊維密度は１０倍異なること
になる。Since the conventional rotating body is constructed as described above, the density of the reinforcing fibers of the radial direction reinforcing layer decreases as it moves from the inner diameter side to the outer diameter side. If the outer diameter of the directionally reinforcing layer is 10 times the inner diameter, the fiber densities on the outer diameter side and the inner diameter side are 10 times different.

性能の回転体が得られないという問題点があった。Therefore, there is a problem that the strength in the radial direction of the rotating body, especially in the radial direction strengthening layer, decreases as it moves to the outer diameter side, and the fiber density increases on the inner diameter side, so that it is thick in the axial direction. However, there is a problem that a high-performance rotating body cannot be obtained.

目されている。2. Description of the Related Art A flywheel is a system for accumulating rotational energy by rotating a disc at a very high speed.
It is used as a rotating body of a wheel energy storage system), and in order to make this rotating body compact, it is necessary to select a material that can withstand a high peripheral speed. At that time, high specific strength (strength / specific amount) is a criterion for material selection. Therefore, especially in the case of a large flywheel, fiber-reinforced composite materials such as high-strength carbon fiber reinforced plastics are drawing attention.
