[0042] The cabin plate structure provided by the present invention is explained and illustrated in detail below in conjunction with the accompanying drawings of the specification.

[0043] The cabin plate structure provided by the present invention is used for cabin structures such as shelter power stations. The cabin plate structure is made of composite materials, which ensures sufficient structural strength while also enabling the cabin plate to have multiple functions such as heat preservation and stealth, and can also reduce the weight of the cabin plate. The present invention is described in detail below in conjunction with specific implementations:

[0044] In some embodiments, the present invention provides a deck structure such as Figure 1 As shown, it includes: a functional layer 1 and a skeleton layer 2, wherein the functional layer 1 covers the skeleton layer 2, the functional layer 1 is located on the outside of the skeleton layer 2, and is connected to the skeleton layer 2 as a whole. During installation, the cabin plate structure is assembled to the cabin body structure as a whole.

[0045] In this embodiment, if Figure 2As shown, the functional layer 1 includes an outer skin 11, an absorbing layer 12 and an inner skin 13, wherein the outer skin 11 is a wave-transmitting material, the inner skin 13 is a carbon fiber composite material, the absorbing layer 12 is composed of a multi-layer absorbing foam 121, and is arranged between the outer skin 11 and the inner skin 13. The absorbing layer 12 can absorb radar waves, so that the functional layer 1 has a stealth function. The outer skin 11 is composed of a multi-layer resin-based composite material, and has good broadband wave transmission ability, so that radar waves enter the absorbing layer 12 and are absorbed, and has good impact resistance, sufficient strength and rigidity. The inner skin 13 is a carbon fiber composite material, has strong rigidity and strength, and has certain impact resistance and bearing capacity. The inner skin 13 and the outer skin 11 respectively form the inner surface and outer surface of the functional layer 1, and the absorbing layer 12 is arranged between the inner skin 13 and the outer skin 11.

[0046] In this embodiment, the absorbing layer 12 is made of multiple layers of hard absorbing foam 121 and has broadband radar absorbing capability. Optionally, an absorbing pattern is printed on the absorbing foam 121, and the multiple layers of absorbing foam 121 are bonded together by epoxy adhesive. The absorbing foam 121 is a lightweight and high-strength foam. The absorbing pattern is printed on the absorbing foam 121, and then, according to the absorbing performance and the thickness of the sandwich layer, several layers of absorbing foam 121 are bonded together by epoxy adhesive to form the absorbing layer 12. Optionally, as Figure 6 As shown, the absorbing pattern includes one or more of a square, a cross, a circle, or a frame. Optionally, the preparation process of the absorbing layer 12 includes: preparing an absorbing slurry, and making the absorbing slurry into an absorbing foam 121 of a desired thickness and size. Printing an absorbing pattern on the absorbing foam 121, and then testing the absorbing performance, strength, etc. of the absorbing foam 121. The absorbing foam 121 that meets the requirements is multi-layered and bonded by an adhesive to form the absorbing layer 12. Finally, the performance of the absorbing layer 12 is tested, and it is used as a standby after passing the test.

[0047] In some embodiments, the forming process of the functional layer 1 includes:

[0048] Mold preparation, select the mold according to the required size, then lay the outer skin 11 demoulding cloth and guide net in the mold, and then lay the outer skin 11 glass fiber and sandwich foam. Put the absorbing layer 12 into the mold, and then lay the inner skin 13 carbon fiber, and then lay the inner skin 13 demoulding cloth and guide net. Then lay the vacuum bag film, rubber inlet pipe and exhaust pipe, and perform an airtightness check after laying. After the airtightness check is passed, the resin is introduced through the rubber inlet pipe, and the mold is demoulded after the resin is cured, and then trimming, opening holes and other operations are performed to complete the preparation of the functional layer 1. The performance of the functional layer 1 is tested, and it can be used after passing the test.

[0049] Optionally, after the absorbing layer 12 is laid, reinforcing glass fibers may be laid to increase the overall structural strength of the functional layer 1 .

[0050] In some embodiments, Figure 3 As shown, the skeleton layer 2 includes a frame 21 and a filling block 22. The frame 21 is hollowed out, and the filling block 22 is filled into the hollow of the frame 21. The frame 21 mainly plays a structural support role, and the filling block 22 is preferably polyurethane foam, which mainly plays a heat preservation role. Optionally, the frame 21 is formed by splicing composite rods, which has a high structural strength and can reduce weight to achieve lightweight.

[0051] In this embodiment, if Figure 4 As shown, the composite rod includes a support structure 211, which is a tubular structure. The support structure 211 is filled with a filling foam 212, and the outer layer of the support structure 211 is provided with a frame skin 213. Optionally, the support structure 211 is made of epoxy resin, and the frame skin 213 is made of carbon fiber cloth. The molding process of the composite rod includes: the frame skin 213 is wound on the filling foam 212, and a certain gap is formed between the filling foam 212 and the frame skin 213. Then, the epoxy resin material is poured between the frame skin 213 and the filling foam 212 by a vacuum negative pressure adsorption process, and the support structure 211 is formed by high temperature curing. Optionally, when the composite rod is manufactured, the thickness of the support structure 211 at different positions can be different by adjusting the gap size between the frame skin 213 and the filling foam 212, so that the support structure 211 of different thicknesses can be formed according to the different loads at different positions, which can not only ensure sufficient structural strength, but also reduce the use of materials and reduce weight.

[0052] Optionally, two or more composite rods are connected at their intersections by winding fiber cloth, and then multiple support structures 211 can be formed in one piece, avoiding welding operations between metal skeletons. The positions of the composite rods can also be arranged according to the shape of the frame 21, and the one-piece forming can avoid cutting operations.

[0053] In some embodiments, Figure 5 As shown, the skeleton layer 2 also includes a skeleton skin 23, which is arranged on the inner side of the frame 21. The skeleton skin 23 is made of carbon fiber material and is bonded to the frame 21. Optionally, the skeleton skin 23 can be preformed by carbon fiber cloth to form a carbon fiber board while the frame 21 is formed, and then the carbon fiber board and the frame 21 are compositely molded into one body by an adhesive to form a skeleton layer 2 with a skin on the inner side. The functional layer 1 is bonded to the outer side of the skeleton layer 2, that is, the inner skin 13 of the functional layer 1 and the frame 21 are bonded by high-strength structural adhesive to form a cabin structure.

[0054] Alternatively, if Figure 1 , Figure 5As shown, when the skeleton layer 2 is of a special shape, for example, including a plurality of planes forming a bent structure, a lap joint structure 214 is formed between the composite rods connected at the bend, and then bonded by an adhesive to increase the bonding area. At the same time, a carbon fiber angle plate 24 can be added at the connection of the skeleton skin 23 and bonded to the seam of the skeleton skin 23, thereby increasing the structural strength of the connection of the skeleton layer 2.

[0055] Furthermore, the functional layer 1 is butted against the corresponding skeleton layer 2 at the overlap by prefabricated chamfering, and then the composite quartz fiber cloth is bonded to the outer skin 11 at the joint. After the quartz fiber cloth is cured and formed, it is polished to ensure the flatness of the surface, thereby enhancing the stealth.
