Embodiment 1
[0020] exist figure 1 , the composite material is divided into two outer layers 1, 3 and a sandwich layer 2. The sandwich layer 2 is located between the two outer layers 1 , 3 . In this embodiment, the outer layers 1 and 3 are bulletproof steel plates with a thickness of 300 mm, and the main body of the sandwich layer 2 is metal foam such as foamed steel or aluminum foam with a thickness of 100 mm. The gaps in the sandwich layer 2 contain a shear thickening liquid. The sandwich structure of foamed steel or aluminum foam, that is, the outer metal panel, the preparation technology of the sandwich layer metal foam structure has been relatively mature, such as using the cumulative rolling method and plastic forming technology to make a foamed steel or aluminum foam sandwich structure. Firstly, the prefabricated metal foam is prepared by accumulative rolling method, and then the outer layer plate and the sandwich layer are combined by rolling and brazing to make a sandwich structu...
Embodiment 2
[0022] exist figure 2 , the composite material is divided into two outer layers 1, 3 and a sandwich layer 2. The sandwich layer 2 is located between the two outer layers 1 , 3 . In this embodiment, the outer layers 1 and 3 are bulletproof steel plates with a thickness of 10 mm, and the main body of the sandwich layer 2 is a high-strength foam with a thickness of 10 mm, such as glass fiber reinforced polyurethane foam. The preparation method of glass fiber reinforced polyurethane foam is mature and can be obtained from the market (such as Italian CANNON company and German Henneke company). The preparation methods generally include pouring molding method and reaction injection molding method. The pouring molding method is to disperse the glass fiber into the combined polyether by stirring, add a certain proportion of isocyanate after the dispersion is uniform, stir quickly, pour quickly, and solidify. The reaction injection molding method is to stir and mix glass fiber and po...
Embodiment 3
[0024] exist image 3 , the composite material is divided into two outer layers 1, 3 and a sandwich layer 2. The sandwich layer 2 is located between the two outer layers 1 , 3 . In this embodiment, the outer layers 1 and 3 are ordinary glass with a thickness of 5 to 10 mm, and the main body of the sandwich layer 2 is a shear thickening liquid. The shear-thickening fluid sits in the sandwich between the two panes of glass, which are then pressure-bonded together with a high-strength glue such as polycarbonate. A shear-thickening liquid is a smart material, a nanoparticle solvent in a solid-liquid mixture. Normally, it exists in the form of a liquid. When impacted, the shear-thickening liquid becomes a quasi-solid state, which can reduce the impact. When the impact force disappears, the shear thickening fluid returns to a liquid state. A typical shear thickening solution is composed of polyethylene glycol and silicon microparticles, obtained as described in Example 1. The c...
