[0016] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0017] Example: Figure 1 As shown in the figure, the embodiment of this utility model provides a multi-faceted metal-lined composite material insulated box structure, which, from the outside to the inside, includes a fiber composite material surface layer 1, an expansion layer 2, a foam core layer 3, an adhesive layer 4, and a metal lining layer 5. Specifically, the fiber composite material surface layer 1 is a glass fiber composite material surface layer, the expansion layer 2 is a thermally expanded foam layer, the adhesive layer 4 is an adhesive film layer, and the metal lining layer 5 is a titanium alloy lining layer.

[0018] In some embodiments, the device also includes corner reinforcements 6, which are plastic protective corner pieces. The toughness of the plastic protective corner pieces increases the drop resistance of each corner of the box.

[0019] A glass fiber composite material 1 is used as the surface layer, which is made by using composite glass fiber fabric and epoxy resin as prepregs. Non-woven fabric and high-adhesion epoxy resin can be used as the adhesive film layer, with the film cut into a polyhedral shape to reinforce the bond between the foam core layer 3 and the metal liner layer 5. The metal liner layer 5 is made of titanium alloy welded into a polyhedral liner with a roughened surface to increase interlayer bonding. The foam core layer 3 uses PMI closed-cell foam. The foam is processed according to the shape of the inner support; the expansion layer 2 is made of thermal expansion foam, which expands when heated and tightens all materials to make each layer firmly bonded; the metal inner lining layer 5, the lay-up adhesive layer 4 are placed in sequence on the laying preform tooling, the foam core layer 3 is laid on the lay-up adhesive layer 4, corner reinforcements 6 are placed at each corner, the expansion layer 2 is then laid on the outside of the foam core layer 3, and finally the fiber composite material surface layer 1 is laid according to the design thickness; the finished blank is transferred to the mold and closed, and then heated and cured to form.

[0020] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
