製造されている。2. Description of the Related Art Conventionally, a honeycomb panel joined by brazing has been widely used as a structural material that is lightweight and has high strength. In particular, in recent years, a honeycomb panel having a curved surface (curved honeycomb panel) has been manufactured as a structural material corresponding to a device having a complicated shape. This type of curved honeycomb panel has been conventionally manufactured by the following methods.

面内では曲率が変化する場合には加工が困難であるとい
う問題があった。However, such conventional methods have various problems. For example, in the general plate bending method described at the beginning, the productivity is not a problem because it is simple, but since the honeycomb core has the property of resisting bending, it is limited only when the radius of curvature is large and small. There is a problem that a curved surface having a radius of curvature cannot be formed. In addition, there is a problem that the processing is difficult when the curvature changes in the same plane.

There was a problem of lacking. Further, in the method shown in FIG. 7B, the honeycomb core P
2 had to be processed into a unique shape, and the workability of the assembly before brazing was poor.

がある。The method shown in FIG. 8 can be said to be the easiest method for obtaining a curved honeycomb panel by brazing, but as shown by the diagonal lines in the figure, the honeycomb core P3 is provided on the convex side of the panel.
Gap (where the cores are not joined) occurs.
That is, a region (non-supporting region P4) where the honeycomb core P3, which is the support, does not exist is generated in the longitudinal direction, so that there is a problem that the structure is weak particularly against repeated bending load in the direction of arrow C.

Is arranged and the face plate 4 on the convex side is arranged. Next, the core materials 2a are placed on the face plate 4 with their trapezoidal tops back to back (that is, the protrusions 7 face down). As a result, the core materials 2a are arranged so as to form the predetermined angle α. In this state, the face plate 3 is placed on each core material 2a, and then the upper die is placed on the face plate 3 via the flat plate 12 of the friction reducing material. In this state, while heating, the surroundings are evacuated and the upper mold 19 pressurizes.
