[0002]

2. Description of the Related Art Honeycomb panel materials having a honeycomb material sandwiched therein are widely used in construction materials and the like. Especially, a honeycomb sandwich panel made of a plastic composite material (hereinafter referred to as a honeycomb panel) is lightweight and has high strength. It is widely used for interior materials such as aircraft flooring materials, wall materials, galleys, lavatory modules, etc., as well as exterior materials such as control surfaces, doors, ducts, fairings, etc. There is.

FIG. 17 shows a general structure of a honeycomb panel, which is a honeycomb core member 1 which is a sandwich material.
Surface materials (referred to as skins) 20a, 20b on both sides of 0
Is adhered, and the decorative material 30 is attached to both or one of the surfaces of the surface materials 20a and 20b as required to obtain the final product. The honeycomb core member 10 is made of a material such as paper, plastic and aluminum. As a material for aircraft, a core member formed by forming aromatic polyamide short fibers into a paper shape and impregnating it with a phenol resin to form a honeycomb shape is used. Used.

As the surface materials 20a and 20b, plate materials, aluminum and the like are used, but as materials for aircraft, woven fabrics such as glass, aramid, carbon, etc. or single fibers are impregnated with phenol or epoxy resin to form a sheet. Prepreg material is used. Surface material 20a, 2 of prepreg material
0b contains a thermosetting resin and has plasticity at normal temperature. Therefore, the surface material 20 is provided on both surfaces of the honeycomb core member 10.
When a and 20b are laminated, and pressure and heat are applied, the surface material 20
The resin impregnated in a and 20b is thermoset and adheres to the honeycomb core member, and the honeycomb panel 1 is formed. If necessary, the decorative material 30 is attached to the upper surface of the surface material with an adhesive film or the like to obtain a final product.

FIG. 18 shows an example of a conventional end surface treatment method. The end surface 70 of the honeycomb panel 1 is shaped into a flat surface, and an adhesive 82 is applied to the inner surface of a channel member 80, which is a shaping member. The end face is shaped. As the channel member 80, for example, an aluminum alloy shaped like a frame can be used. FIG. 19 shows another example of the conventional end surface processing method, in which the core at the end is removed and the recess 74 is formed. The concave portion is filled with the adhesive 82, and after curing, the surface 84 is shaped by grinding or the like to obtain a desired end face.

[0006]

The above-mentioned end surface treatment requires a shaping member (usually aluminum shaping), and this shaping member requires a dedicated member prepared according to the thickness dimension of the honeycomb panel. Therefore, it is difficult to increase the number of parts and reduce the weight, which requires processing man-hours. Further, it is necessary to fill the surface with an adhesive or the like and process the surface after curing. The present invention provides a method for treating an end surface of a honeycomb panel, which solves the above problems.

[0007]

A method for treating an end surface of a honeycomb panel according to the present invention is basically such that a surface material constituting a honeycomb panel is extended from an end surface, and an adhesive is applied to the extension portion to adhere to the end surface. As an effective means. Then, by further projecting this extension from the end face, the end face can be treated by being joined to another honeycomb panel.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION FIGS. 1 to 4 are explanatory views showing an outline of a method for treating an end surface of a honeycomb panel of the present invention. The honeycomb panel 1 has a structure in which the surface materials 20a and 20b are adhered to both surfaces of the honeycomb core member 10, and one end surface 70 of the honeycomb material is treated. As shown in FIG. 2, the one surface material 20 a is processed into a state in which it is extended by a length sufficient to cover the end surface 70. This processing is achieved by preliminarily increasing the dimension of the surface material 20a by the length when the surface material 20a is bonded to the honeycomb core member 10. In the case of a ready-made honeycomb panel, the surface material 20b and the honeycomb core member 10 on the opposite side are cut by a processing machine such as a router to cut the surface material 20a by a predetermined dimension.
Can be extended. Further, as shown in FIG. 4, the surface material 22a may be provided with an extension 24a.

8 to 10 are explanatory views showing the outline of an apparatus used for this end face processing. Table 1 of processing equipment
00 has a flat upper surface, and the surface material 20 a extended on the table 100 is placed so as to be in contact with the table 100. One end of the table has an end plate 110
The pressing plate 120 disposed so as to face the table 100 is mounted on the table 100 by an actuator such as a hydraulic jack 150.
Move up. The pressing plate 120 is guided in parallel with the end plate 110 by an appropriate guide rail or the like. An angle member 130 is placed on the front surface of the pressing plate 120.

A thermoplastic (hot melt type) adhesive 50 is applied between the extension 22a of the surface member 20a and the end face of the honeycomb panel 1, and the pressing plate 120 is pushed forward. The angle member 130 presses the extension portion 22a of the surface material against the end surface of the honeycomb panel. When the adhesive 50 hardens, the extension 22a is fixed while covering the end face.
By the above processing, an end face having a good appearance can be formed. The radius of curvature of the corner portion 25 of the end face can be arbitrarily selected depending on the angle member 130 used.

FIGS. 5 and 6 show a first honeycomb panel 1 having a thick honeycomb core member 10 by using the second honeycomb panel 2 having the thin honeycomb core member 12 end-face-treated by the above means. A means for treating the end face 70 is shown. The second honeycomb panel 2 fixed to the end surface 70 of the first honeycomb panel 1 with an adhesive forms a protruding portion at the edge of the first honeycomb panel 1.
Therefore, as shown in FIG. 7, the panel product 5 made of this honeycomb panel has a low central portion 5a. Therefore, by using this panel product 5 as a door panel or a panel for partitioning, it is possible to obtain a product having a high utility value, which has a frame function with a light edge portion and high rigidity.

13 and 14 show an embodiment in which a honeycomb panel 1c having a surface extension 24a and a honeycomb panel 1 whose end face is not treated are butted against each other to process a corner portion. By applying a hot-melt type or normal adhesive 50 to the abutting surfaces and holding the both with an appropriate jig, it is possible to form a corner portion and perform edge treatment.

FIGS. 15 and 16 show a honeycomb panel 1A having an end surface treatment having no extension of the surface material and a honeycomb panel 1D having one surface material processed with the extension portion 26a. The adhesive 50 is applied to the above to form the corner portion. The outside of the corner portion has a structure in which two surface materials are polymerized, and the rigidity becomes higher.

In FIG. 11, an extension 210b is provided to extend one surface material 200b of the straight honeycomb panel 200 from the straight end surface 202, and while the extension 210b passes through the forming rollers 310, 320, 330. Shows a method of continuously bending so as to cover the end portion. In the vicinity of the first molding roller 310, a hot-melt type adhesive 50 is appropriately applied and applied to the bent portion. The long honeycomb panel 200 presses the upper surface with the pressing roll 340 to prevent the floating.

FIG. 15 shows a processing method when the end surface of the honeycomb panel 220 having an end surface 222 having a curvature is covered with a surface material. The surface material 220b has an extension portion 230b protruding from the end surface 222 by a certain length, and the extension portion 230b is sequentially bent by the forming rolls 310, 32, 330 to cover the end portion. Applying the hot-melt type adhesive 50 appropriately in the vicinity of the first molding roll 310 is the same as in the previous embodiment. By moving the honeycomb panel 220 such that the end surface 222 is always pressed against the forming roll, the treatment of the end surface having a curvature is achieved.

[0016]

As described above, according to the present invention, an end face of a honeycomb panel formed by adhering a surface material to both surfaces of a honeycomb core member is covered by bending an extension portion of the surface material, and a hot-melt type adhesive agent. Since the end surface treatment is performed by joining with, the end surface treatment having excellent appearance and high rigidity can be performed without using a shaping member for the end surface.
