The honeycomb core material 1A or the aluminum brazing sheet honeycomb core material 1A is aligned and laminated in the shape of the honeycomb core 1, and the face plates 2 and 2 made of an aluminum brazing sheet in which the brazing material 2B is clad on one surface of the aluminum plate 2A on the upper and lower surfaces. After being placed and fixed with a jig, the honeycomb core 1 and the face plates 2 and 2 are integrally brazed and joined by heating in a brazing furnace.

とが一体にろう付けされる。In brazing and joining a honeycomb panel, as shown in FIG. 9, the brazing filler metal 2B of the face plates 2 and 2 arranged above and below the honeycomb core 1 is melted, and as shown in FIG. Fillets F1 and F2 are formed at the joints between the honeycomb core 1 and the face plates 2 and 2.

In the case where the brazing material droops down drastically, the core material 1A in the molten brazing material on the lower surface portion melts, and as a result, the core material 1A buckles and collapses, as shown in FIG. 1A drops downward, a gap is created in the upper surface side joint portion, and the fillet F1 formed up to that point is cut.

Further, in the case of a curved honeycomb panel, at the time of brazing and joining, as shown in FIG. 13, the brazing material 2B of the face plates 2 and 2 flows down to the lowermost part of the curved honeycomb panel, and a large amount of brazing material reservoir F3 is formed. As a result, melting (erosion) of the honeycomb core material 1A was apt to occur, often resulting in poor bonding.

トを使用することもできる。That is, a honeycomb core 1 is constructed by laminating a core material formed by stacking a corrugated aluminum honeycomb core material 1A and a polymerized honeycomb core material 1B, and if necessary, a frame material 3 is provided at an end portion. They are arranged, and face plates 2 and 2 made of an aluminum brazing sheet are arranged on both upper and lower sides thereof and heated to a brazing temperature. When the honeycomb core is made of the polymerized core material, as shown in FIG. 2, the dimension d is between the polymerized core materials 1A and 1B.
Since a gap D of 1 and d 2 is generated, as shown in FIG. 3, the molten brazing material of the upper face plate 2 flows into the gap D on the upper surface side to reduce the amount of sagging of the brazing material and reduce the lower surface side. Then, since the molten brazing material of the lower face plate 2 is sucked up into the gap D and the excess brazing material at the joint is reduced, buckling and collapse of the core material due to erosion are prevented, and proper fillets F1 and F2 are formed. It The fact that the core is composed of the honeycomb core 1A and the superposed honeycomb core material 1B and is formed in double also helps prevent buckling and collapse.
The honeycomb core material 1A and the polymerized honeycomb core material 1B
For this, it is preferable to use a bare material, but a brazing sheet can also be used.

せることができる。When the increase in the weight of the honeycomb panel causes a problem in use, as shown in FIG. 5, the polymerized honeycomb core material 1 is used.
B can be formed to a height lower than that of the honeycomb core material 1A. Also in this case, at the time of brazing the honeycomb core and the face plate, the brazing material of the lower face plate is sucked up into the gap D between the honeycomb core material 1A and the polymerized honeycomb core material 1B, and the excess brazing at the joint portion is reduced, Buckling and collapse of the core material due to erosion can be prevented. Further, although not shown in particular, by charging fine aluminum fragments such as aluminum cutting chips into the cells of the honeycomb core, it is possible to cause the molten braze to flow and suck.

なり、溶融ろうの溜まり部の形成が防止される。A honeycomb panel in which face plates 2 and 2 are arranged on the upper and lower surfaces of a core 1 formed by superposing a honeycomb core material 1A and a superposed honeycomb core material 1B and integrally brazed is particularly applied to a curved honeycomb panel. In this case, it is effective to prevent the formation of a molten brazing material pool due to the flowing of the molten brazing metal to the lowermost portion of the curved honeycomb panel. A corrugated honeycomb core material 1A and a superposed honeycomb core material 1B are laminated to form a curved honeycomb core 1, and a curved face plate 2 is formed on the upper and lower surfaces thereof.
When 2 are arranged, fixed with a jig and heated in a brazing furnace, the molten braze flows into the gap D between the honeycomb core material 1A and the polymerized honeycomb core material 1B at the upper surface portion, and melts at the lower surface portion. Is sucked up into the gap D, the amount of the molten brazing material flowing to the lowermost portion of the curved honeycomb panel is extremely small, and the formation of the pooled portion of the molten brazing material is prevented.

ア材とすることもできる。In FIG. 1, all core materials are double core materials in which the honeycomb core material 1A and the superposed honeycomb core material 1B are superposed, but depending on the size and shape of the honeycomb panel to be manufactured, As shown in FIG. 7 and FIG. 8, double core materials may be arranged in the honeycomb core 1 at intervals. Since the brazing filler metal on the face plate is on the entire surface of the core 1 and the molten brazing filler metal communicates with all the cells of the honeycomb core, even when the molten brazing filler metal is locally sucked up,
The effect of forming a fillet having an appropriate size at the joint portion of the lower surface portion extends to all cells. In the case of a curved honeycomb panel, the double core material may be provided only in the vicinity of the lowermost portion where the brazing filler metal is easily formed. If necessary, a triple or more core material can be used.

The brazing filler metal flows into the absorber at the upper surface to reduce the amount of flow-down, and since the surplus brazing filler is sucked up by the absorber at the lower surface, melting (erosion) of the core material due to the molten brazing is prevented,
Appropriate fillets are formed on the upper surface and the lower surface to achieve a sound brazing joint.

である。As described above, according to the present invention, the flow amount of the molten brazing filler metal at the time of brazing and joining the honeycomb panel is reduced, and in particular, the melting (erosion) of the core material at the joint portion on the lower surface side is suppressed. Therefore, the occurrence of defective joints is drastically reduced. In particular, it is effective when applied to a curved honeycomb panel and can significantly improve the bonding quality of the curved honeycomb panel. The same honeycomb core material can be used as the polymerized honeycomb core material to be overlaid on the honeycomb core material, and the simple operation of assembling the honeycomb core suffices, so the work time is slightly increased compared to the conventional method.
