In this method, in addition to the opposite direction, the thinly sliced laminate is forcibly deformed back so that the three-layer folded sheet bends again and is newly bent at the boundary between the adhesive application area and the non-adhesive application area.

A laminate of folded sheets is made.

テンレススチール箔コアが得られるので好ましい。The method of applying the adhesive interposed between the three-layer folded sheet is arbitrary. For example, in the case of the above-mentioned three-layer folded sheet, the adhesive may be applied to all or part of the outer surface of the box folds, and in particular, the adhesive may be applied in a single row only in the center of the outer surface of the box folds, or in two rows on both left and right sides of the outer surface. This is preferred because the application results in a stainless steel foil core with a complex cell shape.

不要となるので、よシ好都合である。Furthermore, before applying the adhesive, it is preferable to perform appropriate surface pretreatment on the surface of the three-layer folded sheet to which the adhesive is to be applied, thereby increasing the activity of the surface and improving the adhesive effect. Examples of pretreatment include physical treatments such as buffing, sandblasting, and polishing, chemical treatments such as acid treatment and alkali treatment, and degreasing treatment using chlorinated solvents, acetone, and the like. It is convenient to use a stainless steel foil that has been previously subjected to degreasing treatment, etc., since it eliminates the need for a pretreatment step for the three-layer folded sheet.

It is best to do this by adding it for a period of time.

It is then expanded in the stacking direction to form honeycomb-like porous cores with various cell shapes. As described above, the thinly sliced laminate is stretched until it becomes almost planar, and then a surface pressure of, for example, 11 to 10 kg/-〇 is applied, or the laminate is then returned to its original position by applying pressure in the opposite direction to the stretching direction. It is preferable to deform it. Further, the dimensions of each core cell are determined by the distance between the folded portion of the three-layer folded sheet and the adjacent folded portion (distance between creases). By changing this spacing design, it is possible to produce cores with a cell diameter of, for example, 2 to 30 m, preferably 3 to 8 m.

も、ステンレススチール箔自体の損傷は殆ど生じない。- When you try to open it again after folding it, a large restoring force acts and it tries to fold again at the crease. Accordingly, according to the process of the method of the present invention, a number of tri-folded sheets of successively folded stainless steel foil are laminated and then the sliced laminate is folded open, preferably so that each tri-folded sheet is approximately When stretched and deformed until it becomes flat, and then the tensile force for stretching is released, the sliced laminate deforms by folding again at the creases, resulting in a honeycomb-like porous stainless steel core with various cell shapes. is formed. That is, in the method of the present invention, a stainless steel foil core is formed by utilizing the high rigidity and strong restoring force of stainless steel foil. In the method of the present invention, even if the thinly sliced laminate is forcibly returned to deformation by pressure in the direction opposite to the stretching direction after being stretched to the maximum extent, the stainless steel foil itself is hardly damaged.

。On the other hand, aluminum foil, which has traditionally been widely used as panel core material, has lower rigidity than stainless steel foil, so when it is folded and then unfolded, large distortions often remain at the fold. Cracks may develop on their own or the bent parts may break off if the cracks develop further.

コアとなってしまう。Therefore, even if a laminated panel core is manufactured by a method similar to the method of the present invention using aluminum foil, cracks in the foil, deformation of the three-layer folded sheet, etc. are likely to occur, and it is difficult to back-produce the core. Even if it could be produced, it would result in a panel core with very low strength.
