Embodiment

[0036] A kind of shelter large board with radar stealth function of the present invention, such as figure 1 Shown, comprise outer skin layer 1 and inner skin layer 3, be provided with reinforcement frame 2 between outer skin layer 1 and inner skin layer 3, in the cavity that forms between outer skin layer 1, inner skin layer 3 and reinforcement frame 2, and The reinforcing frame 2 is provided with alternately stacked layers of rigid foam and absorbing material.

[0037] In this embodiment, the reinforcing frame 2 is made of glass fiber fabric reinforced vinyl ester resin composite material, and has an open groove structure with a wall thickness of 2mm. The reinforcement frame 2 is filled with the first wave-absorbing material layer 4, the first rigid foam layer 7, the second wave-absorbing material layer 5, the second hard foam layer 8, and the third wave-absorbing material layer 6 from the outside to the inside. And the third rigid foam layer 9.

[0038]In this embodiment, ...

Abstract

The invention discloses a shelter slab with radar stealth function and a preparation method thereof. The shelter slab includes an outer skin layer and an inner skin layer, a reinforcing frame is provided between the outer skin layer and the inner skin layer, and alternating Layers of superimposed rigid foam and absorber material. The preparation method includes (1) forming the outer skin; (2) preparing composite channel profiles and splicing them into a reinforcement frame, and stacking rigid foam and wave-absorbing materials alternately in the reinforcement frame; (3) combining the outer skin with The reinforcement frame is bonded, and then the outer skin and the space outside the reinforcement frame are alternately stacked with rigid foam and wave-absorbing materials, and then the inner skin is bonded; (4) The entire board is pressurized and shaped to obtain the large board of the shelter. The shelter slab of the invention has the advantages of light weight, good radar stealth performance, and simple and convenient preparation method.

Description

technical field [0001] The invention belongs to the technical field of shelters, and in particular relates to a shelter slab with a radar stealth function and a preparation method thereof. Background technique [0002] The square cabin refers to a workshop that can provide a suitable working environment and safety protection for personnel and equipment, and is convenient for loading, unloading and transportation in various ways. The shelter is a structure similar to a container, which can be transported by cars and trains. It can provide a suitable environment for equipment and personnel in the cabin, and can be loaded with various functional equipment to form command and control shelters, communication shelters, meteorological shelters, Electronic reconnaissance shelters, mechanical maintenance shelters, hospital shelters, etc. [0003] In the 1950s, the United States began to develop shelters. After decades of development and testing, it has fully proved the superiority o...
