た。The following problems have been pointed out in such a conventional example. As described above, in the conventional honeycomb core 9 made of fiber-reinforced plastic, first, the corrugated sheet 5 formed by the fiber-reinforced plastic prepreg sheet 1 is completely cured, and then the completely cured corrugated sheet 5 is formed. Since it was manufactured by stacking and adhering with the adhesive 6, the problem of low adhesive strength was pointed out. That is, the corrugated sheet 5 molded from the completely cured fiber reinforced plastic prepreg sheet 1 has a completely flat and smooth mirror-finished outer surface because the resin oozes and is cured by heating and pressing. Even if a strong adhesive is used, the bonding force tends to be insufficient, and it has been pointed out that the adhesive strength between them is uncertain. Therefore, in the conventional honeycomb core 9 made of fiber reinforced plastic having the corrugated plate 5 as the cell wall 7, it is pointed out that the adhesive strength between the cell walls 7 is unsatisfactory, and the cell wall is peeled, broken, broken, or the like. There was a problem in terms of quality, such as the occurrence of problems.

By stacking them and then completely curing and adhering them, firstly, the adhesive strength between the cell walls is excellent, and secondly, this is easily and easily realized. It is an object to propose a method for manufacturing a plastic honeycomb core.

る。The technical means of the present invention for achieving this object is as follows. First, claim 1
Is as follows. That is, in this method for manufacturing a honeycomb core made of fiber reinforced plastic, first, a prepreg sheet of a fiber reinforced plastic as a base material is supplied to a corrugate molding device such as a gear or a rack without being completely cured and heated. By pressurizing, a corrugated plate in which corrugated irregularities are continuously bent is formed. Then, a plurality of the corrugated sheets made of the prepreg sheet in a state where the prepreg sheet is not completely cured are stacked in a positional relationship of aligning the valley portion and the top portion while interposing an adhesive, and the prepreg sheet or By heating at the curing temperature of the adhesive, the corrugated sheet made of the prepreg sheet is completely cured, and the adhesive is melt-cured to bond the corrugated sheets.
As a result, a honeycomb core, which is a planar aggregate of hollow columnar cells, is formed by partitioning and forming the corrugated plate as cell walls. Next, claim 2 is as follows. That is,
The method for manufacturing a honeycomb core made of fiber reinforced plastic according to claim 2 is the same as the method for manufacturing a honeycomb core made of fiber reinforced plastic according to claim 1, wherein the corrugated sheet itself made of the prepreg sheet is used without using the adhesive. The corrugated sheets are bonded to each other by complete curing by heating.
