されていた。The conventional honeycomb structure made of fiber reinforced plastic is usually manufactured by the so-called corrugation method. That is, such a prepreg-shaped base material sheet made of fiber reinforced plastic is first pressure-molded into a corrugated shape using a gear, rack, or other corrugation molding device, and this is directly processed by a dedicated mold jig. While maintaining the shape, it is heat-cured in a furnace or the like, so that it is finally formed into a corrugated plate. Then, by stacking a plurality of such corrugated sheets and bonding them with an adhesive or the like, a honeycomb structure made of fiber reinforced plastic has been manufactured.

とおりである。The following problems have been pointed out in the conventional honeycomb structure made of fiber reinforced plastic. First of all, it was pointed out that when the base material sheet is formed into a corrugated sheet, it takes an extremely long time and labor to be heat-cured. That is, carbon, glass, ceramics, Kevlar, and other non-metal fibers that compose the base material sheet made of fiber reinforced plastic are
Since it lacks self-shape retention, the base material sheet is formed into a corrugated sheet by heating and curing the resin that has been combined with such non-metallic fibers by adhesion, impregnation, and mixing over time. It had been. In other words, the base material sheet made of fiber reinforced plastic cannot hold the corrugation by simply press-molding it into a corrugation using a corrugated molding device such as a gear or a rack. While being inserted into the jig and holding the shape, the resin is hardened by heating in a furnace for a long time, so that the hardened resin holds the shape of the corrugation, and finally it is molded and processed as a corrugated sheet. It was It is well known that heat curing of a resin, particularly heat curing of a thermosetting resin, requires a long time.

あった。Secondly, it has been pointed out that the conventional honeycomb structure made of fiber reinforced plastic has a problem in heat resistance strength. That is, as described above, since the corrugated sheet forming the honeycomb structure was held in the corrugated shape by the cured resin, when heated for some reason during use, the resin was melted and easily corrugated. However, the shape of the honeycomb structure, which is a planar aggregate of hollow columnar cells, is liable to be impaired.

ある。These will be described in more detail. First, regarding the corrugated plate 4 formed as described above, for example, an adhesive is applied in a lateral direction such as the bottom surface of the wave bottom or the top surface of the top, and the corrugated board 4 thus coated with the adhesive is After the adhesive is dried, it is cut into a predetermined length. Then, a large number of corrugated sheets 4 are sequentially shifted up and down by half a pitch of the wave, and in a laminated block shape in which there is a space as a whole under the positional relationship of aligning the valley and the top with each other. Although piled up, a flat plate 5 made of fiber reinforced plastic similar to the above-mentioned base material sheet 3 may be further interposed between such corrugated plates 4 ((5) in FIG. 1 described later). Figure and (2) of Figure 2
See figure). After that, the corrugated sheets 4 piled up in this way
Is heated and pressurized in a furnace or the like. By such heating and pressurization, the resin forming the corrugated sheet 4 is cured (when a thermosetting resin is used, it is cured immediately, and when a thermoplastic resin is used, The heating is used as a preheat and is cured by subsequent cooling), and at the same time, the applied adhesive is cured, so that the stacked corrugated sheets 4 are bonded to each other. Of course, when the flat plate 5 is interposed, the corrugated plates 4 and the flat plate 5 are also bonded. In the above example, a bonding method using an adhesive was adopted,
Alternatively, a joining method using a brazing material may be adopted,
Furthermore, a joining method using melting and hardening by heating the resin forming the corrugated plate 4 can be adopted instead of adhesion or brazing.

能となる。Secondly, in this honeycomb structure 1 made of fiber reinforced plastic, the corrugated plates 4 and the like constituting the cell walls 6 thereof are held in shape by the metal fibers 2. After that,
Even if it is heated for some reason at the time of use, like the conventional example of this kind using the non-metal fiber described above, the resin is not melted and the shape is not easily deteriorated. Even if the resin is partially melted, the metal fiber 2 can maintain the overall shape. Therefore, the honeycomb structure 1 made of the fiber reinforced plastic is close to the heat resistance strength of the metal fiber 2 as a material.
The heat resistance strength is improved. As a joining method between the corrugated plates 4, that is, between the cell walls 6, it is possible to more reliably improve the heat resistance strength by using a brazing material without using an adhesive.

容易に製造コスト面に優れて製造可能である。First, it can be manufactured easily and easily. That is, unlike the above-described conventional honeycomb structure made of fiber reinforced plastic of this kind, it does not take a long time to form a corrugated plate, and the time and effort required for insertion into a dedicated mold jig are low. The honeycomb structure made of fiber reinforced plastic is excellent in manufacturing cost, since the corrugated sheet can be easily formed easily without requiring. Even when the expansion method is used instead of the corrugation method, the manufacturing cost can be easily and easily improved according to the method.

Unlike the honeycomb structure made of the fiber-reinforced plastic of the conventional example of this kind described above, the shape is not easily damaged by heating, and the shape is retained by the metal fiber even when heated. The honeycomb structure made of reinforced plastic has a significantly improved heat resistance. in this way,
The effects of the present invention are remarkably large, such as the problems existing in this type of conventional example are eliminated.
