Description

Technical Field

[0001] The utility model relates to the technical field of new material preparation, in particular to a ceramic-based bulletproof and explosion-proof composite structure. Background Art

[0002] In order to protect personnel and equipment from being harmed by bullets and bomb explosion fragments, it is necessary to use equipment made of bulletproof and explosion-proof materials to protect personnel and equipment. In addition to various bulletproof steels and high-performance fiber resin composite materials, ceramic-based bulletproof composite materials are also a kind of bulletproof materials with particularly excellent performance. In practical applications, facing complex battlefield environments, ceramic-based bulletproof composite materials not only need to face the penetration of bullets and explosion fragments, but also need to resist the shock wave of bomb explosions. However, due to the hard and brittle characteristics of the ceramic layer, on the one hand, the ceramic-based bulletproof composite material can hardly resist the shock wave, and the hard and brittle ceramic layer material is broken, thereby reducing its bulletproof and explosion-proof function; on the other hand, the hard and brittle ceramic layer makes it difficult to perform secondary processing, which increases the difficulty of mechanical processing of the ceramic-based composite material, which causes problems such as the difficulty of connecting the ceramic-based composite material with its components, seriously reducing the battlefield adaptability and scope of use of the ceramic-based bulletproof composite material. Utility Model Content

[0003] To this end, the technical problem to be solved by the utility model is to overcome the deficiencies in the prior art and provide a ceramic-based bulletproof and explosion-proof composite structure, which can simultaneously meet the bulletproof requirements and resist bomb explosion impact, and can facilitate the secondary processing of ceramic-based bulletproof and explosion-proof materials or connect them with other components.

[0004] In order to solve the above technical problems, the utility model provides a ceramic-based bulletproof and explosion-proof composite structure, including: a weather-resistant layer, a ceramic layer, a honeycomb panel layer, an anti-penetration layer and prefabricated bolts, the ceramic layer is arranged between the weather-resistant layer and the honeycomb panel layer, the anti-penetration layer is arranged on the bottom surface of the honeycomb panel layer, and the prefabricated bolts penetrate the honeycomb panel layer and the anti-penetration layer for connection with other components.

[0005] In one embodiment of the present invention, the honeycomb panel layer includes a front panel, a honeycomb core layer and a rear panel, and the honeycomb core layer is arranged between the front panel and the rear panel.

[0006] In one embodiment of the utility model, the honeycomb core layer includes a plurality of polygonal honeycombs. When the honeycomb core layer is impacted, the energy is absorbed by the deformation of the honeycomb core layer, thereby further absorbing the kinetic energy of the bullet.

[0007] In one embodiment of the utility model, the prefabricated bolts are connected to other components by welding or threading. The prefabricated bolts penetrate the honeycomb core layer, the rear panel, and the anti-penetration layer, and the ceramic-based bulletproof and explosion-proof composite material can be connected to other components by welding or threading through the prefabricated bolts, which reduces the difficulty of connecting the ceramic-based bulletproof composite material with other components.

[0008] In one embodiment of the present invention, the number of prefabricated bolts is four.

[0009] In one embodiment of the present invention, the prefabricated bolt comprises a bolt head and a screw rod, and the bolt head is located in the honeycomb hole of the honeycomb core layer.

[0010] In an embodiment of the present invention, the bolt head is bonded to the rear panel and the honeycomb by epoxy adhesive.

[0011] In an embodiment of the present invention, a screw hole adapted to the screw rod is provided on the rear panel.

[0012] In one embodiment of the utility model, the weather-resistant layer, ceramic layer, front panel, honeycomb core layer and rear panel are sequentially bonded together by epoxy glue. First, the weather-resistant layer, ceramic layer, front panel and honeycomb core are sequentially bonded by epoxy glue, then holes of the same size as the screws are drilled at the positions where bolts need to be prefabricated on the rear panel, the bolt heads are coated with glue and placed in the honeycomb core, then the rear panel is passed through the bolts, and the rear panel, bolt heads and honeycomb core layer are connected together by epoxy glue, and finally the anti-penetration layer is laid on the upper layer of the rear panel.

[0013] In one embodiment of the present invention, the anti-penetration layer is made of fiber resin material.

[0014] The above technical solution of the utility model has the following beneficial effects compared with the prior art:

[0015] The utility model discloses a ceramic-based bulletproof and explosion-proof composite structure, which can simultaneously meet the bulletproof requirements and resist the impact of bomb explosion. When a bullet arrives, the weather-resistant layer and the ceramic layer first absorb the shock wave. When the bullet arrives at the ceramic layer, the bullet head is passivated, broken and flattened, and the ceramic layer is partially powdered. Then the bullet penetrates the ceramic layer, and then the ceramic layer transfers the energy to the honeycomb core layer, which absorbs its energy through the deformation of the honeycomb core layer, and further absorbs the kinetic energy of the bullet. When the bullet reaches the anti-penetration layer, the anti-penetration layer resists the penetration of the bullet. Moreover, the design of the prefabricated bolts can facilitate the secondary processing of the ceramic-based bulletproof and explosion-proof materials or the connection with other components.

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0024] Reference Figure 1 As shown, a ceramic-based bulletproof and explosion-proof composite structure of the utility model includes: a weather-resistant layer 1, a ceramic layer 2, a honeycomb panel layer 3, an anti-penetration layer 4 and a prefabricated bolt 5, wherein the ceramic layer 2 is arranged between the weather-resistant layer 1 and the honeycomb panel layer 3, and the anti-penetration layer 4 is arranged on the bottom surface of the honeycomb panel layer 3. The honeycomb panel layer 3 includes a front panel 31, a honeycomb core layer 32 and a rear panel 33, wherein the honeycomb core layer 32 is arranged between the front panel 31 and the rear panel 33. The prefabricated bolt 5 runs through the honeycomb panel layer 3 and the anti-penetration layer 4 for connection with other components. Specifically, the prefabricated bolt 5 runs through the honeycomb core layer 32, the rear panel 33 and the anti-penetration layer 4 for welding or threaded connection with other components. The prefabricated bolt 5 includes four. The weather-resistant layer 1, the ceramic layer 2, the front panel 31, the honeycomb core layer 32 and the rear panel 33 are sequentially bonded together by epoxy adhesive. In this embodiment, the weather-resistant layer 1 includes a lightweight skin material such as aluminum and titanium, and the ceramic layer 2 is composed of a hard material such as ceramic.

[0025] like Figure 3 As shown, the honeycomb core layer 32 includes a plurality of polygonal honeycombs 321 .

[0026] like Figure 5 As shown, the prefabricated bolt 5 includes a bolt head 51 and a screw rod 52, and the bolt head 51 is located in the honeycomb hole of the honeycomb core layer 32. The prefabricated bolt 5 can be used to connect the ceramic-based bulletproof and explosion-proof composite material with other components through welding or threaded connection, and the prefabricated bolt 5 reduces the difficulty of connecting the ceramic-based bulletproof composite material with other components.

[0027] like Figure 4 As shown, the bolt head 51 is bonded to the rear panel 33 and the honeycomb 321 by epoxy adhesive. The rear panel 33 is provided with a screw hole 331 adapted to the screw rod 52. The prefabricated bolt 5 penetrates the rear panel 33 and the anti-penetration layer 4.

[0028] In this embodiment, the anti-penetration layer 4 is made of fiber resin material.

[0029] The use method and working principle of the ceramic-based bulletproof and explosion-proof composite structure based on the above structure are as follows:

[0030] First, use epoxy glue to glue the weather-resistant layer 1, ceramic layer 2, front panel 31 and honeycomb core layer 32 in sequence, then drill a hole of the same size as the screw 52 at the position where the prefabricated bolt 5 is required on the rear panel 33, apply glue to the bolt head 51 and place it in the honeycomb core layer 32, then pass the rear panel 33 through the prefabricated bolt 5, and use epoxy glue to connect the rear panel 33, the bolt head 51 and the honeycomb core layer 32 together, finally lay a fiber resin layer material, i.e., the anti-penetration layer 4, on the upper layer of the rear panel 33.

[0031] The current mainstream ceramic-based bulletproof materials can protect against fragments of bullets and bomb explosions, but cannot protect against shock waves of bomb explosions. The hard and brittle ceramic layer 2 material is broken, thereby reducing its bulletproof and explosion-proof functions. Moreover, once the ceramic-based bulletproof material is formed, the hard and brittle ceramic layer 2 makes it difficult to perform secondary processing, which reduces the wide applicability of the ceramic-based bulletproof material, which is suitable for the preparation of various bulletproof and explosion-proof armor, bulletproof inserts and bulletproof shields. The ceramic-based bulletproof and explosion-proof composite structure described in the utility model, when facing the penetration of bullets and explosion fragments, the weather-resistant layer 1 and the ceramic layer 2 first absorb the shock wave, the weather-resistant layer 1 and the front panel 31 can prevent the ceramic layer 2 from falling off, when the bullet reaches the ceramic layer 2, the bullet head is passivated, broken and flattened, the ceramic layer 2 is partially powdered, and then the bullet penetrates the ceramic layer 2 to further absorb the kinetic energy of the bullet, when the bullet reaches the anti-penetration layer 4, the anti-penetration layer 4 resists the penetration of the bullet, when the ceramic-based bulletproof and explosion-proof composite material faces the explosion shock wave, the weather-resistant layer 1 and the ceramic layer 2 first absorb the shock wave, and then the ceramic layer 2 transfers the energy to the honeycomb core layer 32, and absorbs its energy through the large deformation of the honeycomb core layer 32, the ceramic-based bulletproof material can only prevent bullets and explosion fragments, but not explosion shock waves, and also solves the problem that the ceramic-based bulletproof material is difficult to process secondary and connect with other components.

[0032] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
