Embodiment 1

[0036] A kind of square cabin big plate with radar stealth and bulletproof function of the present invention, such as figure 1 As shown, the shelter slab includes an outer skin layer 1 , a rigid foam sandwich layer 2 and an inner skin layer 3 from outside to inside (that is, from top to bottom). Among them, the outer skin layer 1 adopts a structure-function integrated design, which is formed by alternately stacking fiber-reinforced composite material layers and wave-absorbing material layers, and has bulletproof and stealth functions.

[0037] In this embodiment, the outer skin layer 1 sequentially includes a first fiber reinforced composite material layer 4, a first wave absorbing material layer 7, a second fiber reinforced composite material layer 5, a second wave absorbing material layer 8 and a second wave absorbing material layer from outside to inside. Three fiber-reinforced composite material layers 6 , the innermost third fiber-reinforced composite material layer 6 is ...

Embodiment 2

[0047] A kind of square cabin big plate with radar stealth and bulletproof function of the present invention, such as image 3 As shown, the shelter slab includes an outer skin layer 1 , a rigid foam sandwich layer 2 and an inner skin layer 3 from outside to inside (that is, from top to bottom). Among them, the outer skin layer 1 adopts a structure-function integrated design, which is formed by alternately stacking fiber-reinforced composite material layers and wave-absorbing material layers, and has bulletproof and stealth functions.

[0048] In this embodiment, the outer skin layer 1 sequentially includes the first fiber reinforced composite material layer 4, the first wave absorbing material layer 7, the second fiber reinforced composite material layer 5, the second wave absorbing material layer 8, the second wave absorbing material layer from outside to inside. There are three layers of fiber reinforced composite material 6 and a third wave-absorbing material layer 9 , and...

Abstract

The invention discloses a shelter slab with radar stealth and bulletproof functions and a preparation method thereof. The large panel of the shelter includes an outer skin layer, a rigid foam sandwich layer and an inner skin layer in sequence from the outside to the inside, and the outer skin layer is formed by alternately stacking fiber-reinforced composite material layers and wave-absorbing material layers. The preparation method includes (1) using the reinforcing fibers and wave-absorbing materials required for fiber-reinforced composite materials as layers, combined with the resin matrix, and adopting vacuum infusion process, molding process or hand lay-up process to form the outer skin at one time; or forming fiber-reinforced materials first Composite materials, and then bond the fiber-reinforced composite material and the absorbing material layer by layer to obtain the outer skin; (2) Bond the outer skin, rigid foam and inner skin to obtain the shelter slab. The shelter slab of the invention has the advantages of light weight, good radar stealth and ballistic performance, and the preparation method is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of shelters, and in particular relates to a shelter slab with radar stealth and bulletproof functions 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 trucks. It can provide a suitable environment for the equipment and personnel in the cabin, and can be loaded with various functional equipment to form command and control shelters, communication shelters, meteorological shelters, and electronic reconnaissance shelters. Sheds, shelters for machinery maintenance, shelters for hospitals, etc. [0003] In the 1950s, the United States began to develop shelters. After decades of development and testing, it has f...
