Description of the Invention: [Technical Field of the Invention] The present invention relates to a structure of a composite sheet and a method for producing the same, and more particularly to a nest sandwich panel and a method of making the same.哞【Prior Art】 Conventional composite sheets such as sandwich panels are composed of the upper and lower layers, and the core material in the middle of the upper and lower layers, which can be applied as a partition wall f, a sound insulation board, a table top, Door panels, high-rise floors, and insulation panels, etc.; can also be used in aerospace industry such as engine room and cabin floor and general defense = industry. At the same time, with the continuous development of aerospace technology, the research and development needs of the various honeycombs are also becoming more and more important. As usual, § is made by the process of hot pressing or pressure Cang. For example, as shown in FIG. 1A, the upper surface layer 1〇1, 1〇3 may be hot-pressed first. Then, as shown in FIG. 1B, a sheet of glue (adhesive fUn〇1〇5, 107 is laminated thereon, Between the lower layers 101 and 1〇3, and a honeycomb (fashionable material) (honeycomb core) 109 is disposed between the sheets of glue 1〇5, 1〇7. Then, as shown in Fig. 1C, hot pressing is performed. The sandwich structure is formed. Next, as shown in Fig. 1D, the processing operation of the edge groove is performed to form the side groove 1〇91 where the honeycomb core material 1〇9 is exposed. Finally, as shown in Fig. 1, the filling is performed. In the glue operation, the side groove 10 91 ' is filled with the sealing material 1 〇 93 of the resin to isolate the honeycomb core material 1 〇 9 from the outside. Thus, a honeycomb sandwich panel 1 得到 can be obtained. Hot presses or autoclaves. However, the cost of these equipments is very high, especially the pressure, and the investment cost often exceeds tens of millions of 5 110015 13103421, so the relative increase in manufacturing costs is not conducive to widespread use. At the same time, practical In order to avoid the bareness of the periphery of the sandwich plate, the strength of the knot f is rapidly decreased, and even In order to cause the structural damage of the delamination, it is necessary to carry out the processing operations such as the edge-cutting groove and the filling, and the processing operations such as the edge-cutting groove and the filling are quite complicated and time-consuming, so that the manufacturing cost is relatively increased. It has been proposed to make a honeycomb sandwich panel by resin transfer molding (Resin τ(4)(6) M〇ldlng' RTM). As shown in Fig. 2A, the method is first sealed (4), for example, the separation of thermoplastics, chat, m to the hive. The upper surface of the core material 205 is sealed to seal the upper and lower holes of the honeycomb core material 205. Of course, this step can also seal the lower hole of the honeycomb core material 2〇5 with a thermosetting resin by using a thermosetting resin. As shown in Fig. 2B, the upper and lower layers 2〇7, 2〇9 are respectively laminated to the thermoplastic film 20b to form a sandwich structure. Then, as shown in Fig. 100, the resin transfer molding process is performed. The resin 21 is injected into the upper and lower layers 207 and 209. Subsequently, as shown in Fig. 2D, under the specific | / dish force, 'waiting for a suitable time to make the structure of the resin injected, solid, then, , as shown in Figure 2E, for the edge groove Next, as shown in FIG. 2F, the filling operation is performed, and the side groove 2〇5 is filled with, for example, a resin dense material 2053, so that the honeycomb core material is separated from the outside, so that a honeycomb can be obtained. Sandwich board 20. <2, this conventional technique can prevent the resin from entering when the resin is injected, and the inside and outside of the nest: but the finished sandwich board will still be surrounded by nakedness: The water vapor is allowed to enter. Therefore, such a conventional technique still requires processing operations such as cutting the edge groove and filling the edge seal, and cannot directly integrate into a 6 110015 1310342, #-shaped sandwich panel. It can be seen that although the cost of equipment required for such a conventional resin transfer molding process is lower than that of hot pressing or pressure enthalpy, this does not help to shorten the processing time, and there is still a problem of complicated processing. In addition, as disclosed in U.S. Patent No. 5,569,508, a composite sheet in which a foamed material is poured into a honeycomb of a honeycomb core board, although the sealing step of providing a sheet rubber or a film in the prior art is omitted, the method is formed. The structure of the honeycomb structure of the honeycomb is still a small part of the outer layer of the core, and the barrier to moisture is relatively poor and affects its appearance, and all the holes of the core of the process will be filled with foam. Full, and the disadvantage of causing a structural increase of ^1, the advantages of light weight and degree emphasized by the honeycomb sandwich structure are reduced. X, U.S. Patent No. 5,567, in the case of the addition of an insulating film between the upper and lower layers and the sheet rubber, and after laminating the above five layers and the honeycomb core sheet, and then on the outer surface of the upper and lower layers Fit, cut, and quasi-reinforcing layers. However, this method still requires machining operations such as grooving and filling and sealing, and there are still many shortcomings in the process. Therefore, the manufacturing costs of these conventional technologies are still not cost effective. In addition, the Republic of China Patent Certificate No. 24521 No. 1 is a type of honeycomb fiber material, a glass fiber layer adhered to both surfaces of the honeycomb core material and impregnated with an epoxy tree, and laminated on the glass fiber layer. The outer layer of the layer is composed of the honeycomb three-day m. The patent mainly consists of glass fiber 2 = cloth impregnated with epoxy resin and then allowed to stand for a period of time, after the epoxy resin viscosity is raised: then the (four) the honeycomb core material is The pure wire bag is vacuumed step + after the glass fiber woven cloth is hardened and then the bag is removed to complete the sealing. In addition, the invention patent of the Republic of China Patent No. 562741 is 110015 7 1310342

After that, it can be made into a composite sheet by a resin transfer molding process. However, the second patented technology only prevents the resin from leaking into the pores of the honeycomb core during the resin transfer molding process, but the technique of avoiding the peripheral edge of the sandwich panel and preventing the moisture from penetrating into the honeycomb core material The rapid decline of strength, or even the occurrence of delamination and the destruction of structures, etc., still need to be solved by processing operations such as digging grooves and rubber sealing. {古文, how to have it, to solve the above-mentioned lack of conventional technology, to apply a faster and more economical way to provide a honeycomb sandwich panel with high strength and light weight, which is an urgent problem to be solved in the field. SUMMARY OF THE INVENTION In view of the above-described shortcomings of the prior art, a honeycomb sandwich panel and a method of making the same are provided, which are cost-effective, shorten the process, and simplify the operation. The purpose of the present invention is to reduce equipment investment at the same time.

The resin of the 1U of the tank is 17. The honeycomb core material n can be, for example, any of the inscriptions, plastics, or papers, and has a plurality of hexagonal, quadrangular, circular, or other shapes. Since the honeycomb core material jj can be any conventional honeycomb core material, its structure and function principle are well known, so it is no longer described herein. The sealant material 13 has a larger size than the honeycomb core material n. And it can be a thermosetting fiber cloth composed of a thermosetting resin and a fiber cloth, a fiberboard coated with a viscose or other equivalent sealing material. The fiber cloth may be synthetic fiber γ such as DuPont®, carbon fiber, glass fiber, or other equivalent fiber cloth for resin circulation.
