[0002] Bulletproof and impact-resistant composite glass is a type of glass product with special protective properties. It is usually made of multiple layers of materials with different properties. However, the existing bulletproof and impact-resistant composite glass does not provide good protection when in use and does not have the ability to cushion and absorb shock.

[0003] As disclosed in announcement number CN219564378U, a bulletproof and impact-resistant composite glass includes a main body, a protective component on the main body, and an auxiliary mechanism on the main body. The protective component includes a reflective layer fixed to the back of the main body, a reinforcing layer fixed to the front of the main body, a bulletproof layer fixed to the front of the reinforcing layer, and an impact-resistant layer fixed to the front of the bulletproof layer. This bulletproof and impact-resistant composite glass, with its protective component and auxiliary mechanism, achieves bulletproof and impact-resistant functionality through the cooperation of its various structures. The impact-resistant and bulletproof layers, along with other structural features, allow the composite glass to meet user needs in environments with extremely high safety requirements. It facilitates quick and easy installation and provides a degree of protection after installation, thus improving its practicality. However, this glass does not possess cushioning or shock-absorbing properties during use. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength bulletproof and impact-resistant composite glass to address the problem that existing bulletproof and impact-resistant composite glass does not provide adequate protection and lacks cushioning and shock absorption properties.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength bulletproof and impact-resistant composite glass, comprising: a nano-ceramic outer layer, an amorphous alloy metal glass mesh fixedly disposed at one end of the inner side of the nano-ceramic outer layer, a gradient polymer-permeable glass fixedly disposed at one end of the inner side of the amorphous alloy metal glass mesh, a viscoelastic buffer layer fixedly disposed at one end of the inner side of the gradient polymer-permeable glass, an anti-penetration layer fixedly disposed at one end of the inner side of the viscoelastic buffer layer, an electromagnetic energy dissipation layer fixedly disposed at one end of the inner side of the anti-penetration layer, and a back inner layer fixedly disposed at one end of the inner side of the electromagnetic energy dissipation layer.

[0006] As a further embodiment of this utility model: the outer layer of the nano-ceramic is ZrO2 ceramic reinforced with alumina nanocrystals, and the surface is coated with a photocatalytic TiO2 / SiO2 composite film; the amorphous alloy metal glass mesh is made of Vitra alloy material; and the internal glass mesh of the amorphous alloy metal glass mesh is a micron-level mesh.

[0007] As a further improvement of this invention: the gradient polymer-permeable glass is a multilayer chemically strengthened soda-lime glass, and the silica nanoparticle suspension injected between the multilayer chemically strengthened soda-lime glass is a shear thickening liquid.

[0008] As a further improvement of this utility model: the viscoelastic buffer layer is made of topology-optimized polyurethane material, and the viscoelastic buffer layer is a fractal composite structure with a 3D printed honeycomb shape.

[0009] As a further embodiment of this invention: the anti-penetration layer is made of oriented carbon nanotubes and polycarbonate composite, and the anti-penetration layer is a vertically arranged CNT array embedded in a modified PC matrix.

[0010] As a further embodiment of this utility model: the electromagnetic energy dissipation layer is a structure in which TiO2@BaTiO3 core-shell particles are suspended in silicone oil and external micro-electrode array, and the inner back layer is made of SiO2 flexible aerogel nanofibers and para-aramid woven aramid composite film.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the self-healing nano-ceramic layer uses ZrO2 ceramic reinforced with alumina nanocrystals. The nanocrystals can effectively disperse impact energy, and the high hardness can passivate the bullet head and reduce impact damage. The photocatalytic coating can also decompose surface scratches under ultraviolet irradiation, maintain transparency, and ensure optical performance and protective effect during long-term use. The amorphous alloy metal glass mesh, with the high elastic limit of Vitra alloy, can efficiently absorb impact kinetic energy. The micron-level mesh structure avoids light diffraction, making the glass transmittance greater than 90%, ensuring protection without affecting the visual effect.

[0013] In this invention, the shear-thickening liquid in the gradient polymer-permeable glass solidifies instantaneously upon impact, converting point load into surface load and reducing local pressure. The gradient strengthening design inhibits crack propagation, improving the overall strength and impact resistance of the glass. In the oriented carbon nanotube / polycarbonate anti-penetration layer, the oriented carbon nanotubes guide crack deflection, and the plastic deformation of the polycarbonate consumes a large amount of energy, effectively preventing objects from penetrating.

[0014] In this invention, the topology-optimized polyurethane viscoelastic buffer layer, achieved through 3D printing in a honeycomb-fractal composite configuration, maximizes energy absorption density. Young's modulus gradient distribution matches the acoustic impedance of adjacent layers, reducing interfacial reflection stress and improving buffering effect. The electromagnetic energy dissipation layer applies a kV-level electric field upon impact, causing a rapid 10 kV increase in fluid viscosity. 4 The inner flexible aerogel / aramid composite membrane effectively blocks debris from splashing, further enhancing protective safety. In the inner flexible aerogel / aramid composite membrane, SiO2 aerogel nanofibers block heat conduction, and the para-aramid braid can capture micro-fragments, preventing back-side collapse and ensuring safe use.

The amorphous alloy metal glass mesh 20 is made of Vitra alloy material, and the glass mesh inside the amorphous alloy metal glass mesh 20 is a micron-level mesh.

[0024] The gradient polymer-permeable glass 30 is a multilayer chemically strengthened soda-lime glass, and the interlayer of the multilayer chemically strengthened soda-lime glass is injected with a silica nanoparticle suspension as a shear thickening fluid.

[0025] The viscoelastic buffer layer 40 is made of topology-optimized polyurethane material and has a 3D-printed honeycomb-shaped fractal composite structure.

[0028] Example 2

[0029] Outer passivation and impact dispersion: The self-healing nano-ceramic layer uses ZrO2 ceramic reinforced with alumina nanocrystals. The nanocrystals effectively disperse impact energy, and the high hardness (HV 1500) passivates the projectile, reducing impact damage. The photocatalytic coating can also decompose surface scratches under ultraviolet irradiation, maintain transparency, and ensure optical performance and protective effect during long-term use.

[0030] Energy dissipation and high light transmittance: Amorphous alloy metallic glass mesh, thanks to the high elastic limit (2%) of Vitra alloy, can efficiently absorb impact kinetic energy. The micron-level mesh structure avoids light diffraction, making the glass transmittance >90%, ensuring protection without affecting visual effects.

[0031] Load conversion and crack suppression in the main load-bearing layer: The shear-thickening fluid in the gradient polymer-infiltrated glass solidifies instantaneously upon impact, converting point loads into surface loads and reducing local pressure. This gradient strengthening design inhibits crack propagation, improving the overall strength and impact resistance of the glass.

[0032] Penetration Resistance and Energy Dissipation: In the oriented carbon nanotube / polycarbonate penetration-resistant layer, the oriented carbon nanotubes can guide crack deflection, and the plastic deformation of polycarbonate can dissipate a large amount of energy (80kJ / m). 3 This effectively prevents objects from penetrating.

[0033] Viscoelastic buffer optimization: A 3D-printed honeycomb-fractal composite configuration of a topology-optimized polyurethane viscoelastic buffer layer maximizes energy absorption density. Young's modulus gradient distribution matches the acoustic impedance of adjacent layers, reducing interfacial reflection stress and improving buffering performance.

[0034] Electromagnetic jamming splash: When the electromagnetic energy dissipation layer encounters an impact, it applies a kV-level electric field, causing the fluid viscosity to increase instantaneously by 10. 4 This doubles the strength, effectively preventing debris from flying and further enhancing safety.

[0035] Thermal insulation and anti-collapse: In the inner flexible aerogel / aramid composite membrane, SiO2 aerogel nanofibers block heat conduction (thermal conductivity <0.02W / m·K), and the para-aramid braid can capture micro-fragments to prevent back-side collapse and ensure safe use.
