2. Description of the Related Art Such a curved honeycomb panel has a predetermined curvature by bonding an inner plate and an outer plate made of fiber reinforced plastics (hereinafter simply referred to as FRP) to both surfaces of a honeycomb core as a core material. , As a manufacturing method,
A so-called co-cure method and a curing method are known. Ko
The curing method is a method in which the inner plate and the outer plate are bonded to both surfaces of the honeycomb core without curing using an adhesive in a prepreg state, and the curing method is a state in which the inner plate and the outer plate are in a prepreg state. After being further cured from the honeycomb core, it is bonded to both surfaces of the honeycomb core using an adhesive.However, in the co-cure method, a gap is formed between the inner core plate and the outer core plate in the prepreg state and the honeycomb core. However, there is a disadvantage that the performance of the face plate of the inner plate and the outer plate is reduced. On the other hand, in the curing method, after curing, it is bonded using an adhesive,
Excellent surface performance of inner and outer panels.

The following problems have been pointed out in the conventional examples of such a curing method. First, in this conventional method for manufacturing a curved honeycomb panel 4, the inner surface plate 1 and the outer surface plate 2 are formed as shown in FIG.
(2) At the time of pressure molding in the figure, the prepreg is in a state in which the base material and the resin are combined in a weight ratio of generally 6: 4. Therefore, tolerances occur between the inner plate 1 and the outer plate 2 depending on molding conditions such as temperature, pressure, resin flow, and the like, and the thickness, dimensions, shape, positional accuracy, and the like are likely to fluctuate.
There is variation. On the other hand, the honeycomb core 3 also has tolerances, and its thickness, dimensions, and the like vary. Therefore, when such an FRP inner plate 1, outer plate 2 and honeycomb core 3 are used and bonded with an adhesive, as shown in FIG. 6C, the inner plate 1 and the honeycomb are formed. A gap P is provided between the cores 3 and between the outer panel 2 and the honeycomb core 3.
Is more likely to occur. Therefore, the conventional curved honeycomb panel 4
In such a case, there are many problems such as defective products such as poor adhesion caused by such gaps P. Second, in the conventional method of manufacturing the curved honeycomb panel 4, the inner plate 1 and the outer plate 2 are pressure-formed using dedicated dies A and B, respectively. Therefore, the production of the molds A and B is prolonged, that is, the wooden mold, casting, processing, aging, etc. are not easy, which takes days and increases the cost. It has also been pointed out that the production of 4 itself is troublesome and costly.

FIG. 5 is a front sectional view of another example of the present invention in which the inner plate 6 and the outer plate 7 are simultaneously pressed and formed. FIG. FIG. 2B shows the case where the mold C is used, and FIG. First, in the above-described embodiment, as shown in FIG. 1, although the same mold C is used, the inner plate 6 and the outer plate 7 are separately and separately molded by pressure. However, instead of this, as shown in FIGS. 5A and 5B, the inner plate 6 and the outer plate 7 may be simultaneously pressed and formed. In this case, furthermore, There is an advantage that manufacturing is facilitated and cost is excellent. In this case, reference numeral 11 denotes a release paper interposed between the inner plate 6 and the outer plate 7 in this case, but a release agent may be applied instead. Also, in FIGS. 1 and 3 of the above-described embodiment and FIG. 5 (1) of the embodiment of FIG. 5, a mold C having a concave shape is used, but is of course limited to this. Instead, it may have a shape corresponding to the opposite surface. That is, it is also possible to use a mold having a convex shape, such as the mold C ′ shown in FIG. 5 (2).

As described above, the method for manufacturing a curved honeycomb panel according to the present invention uses a combination of a woven base material and plastics such as resin, and forms a common mold having a predetermined curvature with the inner surface plate. After the outer surface plate is pressure-formed, pressure-forming processing for bonding the honeycomb core to both surfaces is performed, so that the following effects are exhibited. First, since no gap is generated between the inner face plate and the honeycomb core and between the outer face plate and the honeycomb core, poor adhesion due to the gap is prevented. In this way, a curved honeycomb panel free from product defects and excellent in quality and practicality can be obtained. Secondly, the manufacture of the mold is facilitated and the cost is excellent, and the manufacture of the inner and outer panels and the curved honeycomb panel itself is facilitated without labor, and the cost is reduced and the cost is excellent. As described above, the effects exhibited by the present invention are remarkable and large, for example, the problems existing in this type of conventional example are eliminated.
