Description
Technical Field
The utility model relates to the technical field of protective equipment, in particular to an anti-elastic composite material with a negative poisson ratio ceramic structure.
Background
It is generally believed that almost all materials have a positive poisson's ratio and that the material shrinks laterally when it is stretched. Negative poisson's ratio materials expand laterally when stretched and contract laterally when compressed. The presence of the negative poisson's ratio effect tends to give the material some special properties, which in many respects have advantages that other materials cannot compare. Ceramic reinforced resin matrix anti-elastic composite materials are widely applied in various fields, such as armed helicopters, tank armored vehicles, ships, defence works and the like, and especially armaments, such as helicopter, tank armored vehicles and the like, and the mobility of the armaments can be affected if the weight of the armaments is large. Therefore, in this respect, it is required to have better elastic resistance and lighter weight, and the problem of the reduced maneuverability due to the improved protective ability of the equipment is minimized. Therefore, it is desirable to invent an anti-ballistic composite material containing a negative poisson's ratio ceramic structure.
Disclosure of Invention
The utility model aims to provide an anti-elastic composite material with a negative poisson ratio ceramic structure, which can realize lighter quality and better anti-elastic performance under the condition of ensuring the protective capability of equipment.
The technical scheme adopted for solving the technical problems is as follows:
an anti-elastic composite material containing a negative poisson ratio ceramic structure comprises an upper panel and a lower panel which are arranged from top to bottom, wherein a ceramic block layer is arranged between the upper panel and the lower panel, and the ceramic block layer is of a negative poisson ratio structure formed by a plurality of ceramic units; the ceramic unit is of an hourglass structure, and the horizontal section of the ceramic unit is of a regular polygon.
Further, the included angle alpha at the narrow waist of the hourglass-shaped structure of the ceramic unit is 135-160 degrees.
Further, the height of the ceramic unit is 8-30 mm.
The utility model has the beneficial effects that: the anti-elastic composite material containing the negative poisson ratio ceramic structure is light in weight, and the weight of the anti-elastic composite material is greatly reduced compared with that of common ceramic composite armor and homogeneous armor steel materials under the same protection condition; on the premise of the same weight, the anti-elastic performance of the composite ceramic armor is greatly improved compared with that of the common ceramic composite armor and the homogeneous armor steel material; the composite material has good elastic resistance, strong designability and designable protection level, and can effectively protect from common bullets of 7.62mm to armor-piercing combustion bullets of 14.5 mm.

Detailed Description
The anti-elastic composite material with the negative poisson ratio ceramic structure shown in fig. 1 comprises an upper panel 1 and a lower panel 4 which are arranged from top to bottom, wherein a ceramic block layer 2 is arranged between the upper panel 1 and the lower panel 4, and the ceramic block layer 2 is of a negative poisson ratio structure formed by a plurality of ceramic units; the ceramic unit is of an hourglass structure, the horizontal section of the ceramic unit is of a regular polygon, and as shown in fig. 3-5, the horizontal section of the ceramic unit is one of a regular triangle, a regular quadrilateral, a regular pentagon and a regular hexagon; the gaps between the ceramic units are filled with a resin layer 3, and the resin layer 3 is a polyurethane structural adhesive layer and is mixed with ceramic particles. In order to improve the elastic resistance of the composite elastic-resistant plate, the ceramic particles are ceramic balls or ceramic cylinders; the diameter of the ceramic cylinder is 5 mm-10 mm, and the height and the diameter of the ceramic cylinder are the same.
In order to improve the elastic resistance and the adhesion performance of the composite elastic plate, the polyurethane structural adhesive in the resin layer 3 is formed by mixing the two-component polyurethane adhesives of the Macroplast UK 8103 and the Macroplast UK 5400 in a weight ratio of 4:1. And when the weight ratio is 4:1, the two-component polyurethane adhesive can be completely cured.
The resin layer 3 has good elasticity, and when the structural ceramic with the negative poisson ratio is impacted and deformed by the projectile, the resin layer 3 generates elastic deformation, further absorbs the energy transferred by the deformation of the ceramic, and improves the elastic resistance of the composite elastic plate.
Due to the existence of the ceramic ball and the ceramic cylinder, when the ceramic ball and the ceramic cylinder are impacted by the projectile, the ceramic ball and the ceramic cylinder are broken, so that the energy of the projectile is consumed, and the anti-bullet performance of the composite anti-bullet plate is further improved. The ceramic unit and the ceramic particles are made of one of aluminum oxide ceramic, silicon carbide ceramic, boron nitride ceramic and titanium boride ceramic.
In order to improve the elastic resistance and the ceramic chip resistance of the panel while providing the overall rigidity of the panel, the materials of the upper panel 1 and the lower panel 4 are one of aramid fiber (Kevlar 129/Kevlar 149, PBO fiber (PBO-AS fiber, UHMWPE fiber, glass fiber reinforced epoxy resin matrix composite (E glass fiber reinforced epoxy resin matrix composite, etc.); the thickness of the upper panel 1 or the lower panel 4 is 2-20 mm.
Preferably, in combination with the above scheme, as shown in fig. 2, the included angle α at the narrow waist of the hourglass structure of the ceramic unit is 135-160 degrees. In the included angle range, the negative Poisson ratio value of the ceramic structure is-1.5 to-0.35.
Preferably, in combination with the above scheme, in order to ensure better elastic resistance, optimal matching of height, weight and elastic resistance is achieved, and the height of the ceramic unit is 8-30 mm.

The specific meaning of the above terms in the present utility model will be understood in a specific case by those skilled in the art.
While the utility model has been described above by way of example with reference to the accompanying drawings, it will be apparent that the utility model is not limited to the specific embodiments described above, but is intended to cover various modifications of the method concepts and technical solutions of the utility model, or applications without modifications, as such are within the scope of the utility model.
