Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

As shown in fig. 1, the light composite material bullet-intercepting composite board capable of absorbing metal bullets comprises a nonmetal bullet-preventing board 5, flame-retardant foam 4 is respectively arranged on two sides of the nonmetal bullet-preventing board 5, a hard aluminum plate 3 is arranged on the outer side of the flame-retardant foam 4, and a decorative layer 2 is arranged on the outer side of the hard aluminum plate 3. Wherein, nonmetal armour 5 is aramid fibre armour or PE armour, and decorative layer 2 is microfiber skin or aluminium foil. The aluminum foil can be colored aluminum foil or other adhesive covers, so that the attractiveness is improved. A circle of covered edges 1 are arranged around the combined plate, the cross section of each covered edge 1 is U-shaped and can be made of aluminum profiles.

As shown in fig. 2, according to another embodiment of the present invention, the non-metal bulletproof plate 5 is provided in two layers, and a layer of flame retardant foam 4 is provided between the two layers of non-metal bulletproof plates 5. Under the same bullet-intercepting grade requirement, the sum of the thicknesses of the two layers of the nonmetal bulletproof plates 5 is equal to or larger than the thickness of the single layer of the nonmetal bulletproof plate 5. For example, at 0.2 meter direct incidence, a metal bullet cannot shoot through the middle non-metallic ballistic panel. According to the requirements of bullet interception grade, the thickness of the non-metal bulletproof plate can be adjusted, for example, the thickness of 64 and 77 pistols can be 6mm or more (the non-metal bulletproof plate is a single plate or the total thickness of two plates), the thickness of 92 pistols steel core bullets can be 8mm or more (the non-metal bulletproof plate is a single plate or the total thickness of two plates), the thickness of 79 nibbles can be 10mm or more (the non-metal bulletproof plate is a single plate or the total thickness of two plates), and the thickness of 95 rifles can be 30mm or more (the non-metal bulletproof plate is a single plate or the total thickness of two plates).

The outer layer of the bullet-intercepting composite board is a thin aluminum plate and flame-retardant foam, and the metal bullet is directly injected when the angle is not 90 degrees. And the metal fragments are basically absorbed by the non-metal bulletproof plate, and the hard aluminum plate on the outer layer can completely intercept possible bullet skin fragments. The flame-retardant foam filling layer can completely absorb the type variable of the nonmetal bulletproof plate when the metal bullet impacts, so that the nonmetal bulletproof plate can uniformly transmit impact force outwards as much as possible when impacted by a bullet, and the combined plate is ensured not to be obviously protruded.

The middle bulletproof plate of the bullet-intercepting combined plate is made of a non-metal material, and abandons the traditional bulletproof steel plate material, thereby not only ensuring that the metal bullets are not penetrated and intercepted, but also having no flying-out of fragments, and being convenient for moving and using (taking 79 micro-impact steel core bullet interception as an example, the weight of the combined plate is about 15 kilograms per square meter). The combined plate can be used for a gun checking plate, a gun checking cabinet, a movable bullet blocking (avoiding) wall, a bullet blocking (avoiding) partition simulating a block room during military police tactical shooting, and the like.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
