公報）を出願している。Conventional technology For example, as described in pages 88 to 90 of Plastic Age (published by Plastic Age Co., Ltd., May 1986 issue) as a manufacturing method for honeycomb structural materials, high-performance adhesives are used to bond the outer skin and honeycomb. Methods of gluing are known. However, high-performance adhesives have the disadvantage of being expensive and having a small bonding surface because they bond the end faces of the honeycomb material to the outer skin.To improve this, the applicant filled the honeycomb core with hard urethane foam to increase the bonding surface. He has applied for an invention (Japanese Patent Application No. 164286/1983 and 25649/1983) which increases the adhesive strength.

填できる利点がある。 Therefore, in the state after foaming shown in FIG. 9, the face materials 15 and 18 are bonded to each other by the foam 19 via the honeycomb core 17, ensuring a sufficiently large bonding area, so that the mold cannot be opened. The reliability of the strength and rigidity of the product obtained after this process is further improved. Further, foaming and molding can be performed in the same pressure molding process, and there is no need to provide a separate pressure molding process, making it possible not only to reduce the number of processes but also to save space in the factory. In the above embodiment, since the foaming is performed from the top and bottom of the honeycomb core 17, there is an advantage that a sufficient thickness can be ensured and the inside of the honeycomb core 17 can be reliably filled with the foam 19.
