Problems solved by technology

[0004] At present, there are still many aspects that need to be improved in the preparation of bulletproof armor, mainly in the following aspects: (1) the protective requirements restrict the lightweight of armor; (2) the armor's ability to resist continuous penetration damage is insufficient; 3) It cannot meet the higher requirements of armor protection in modern warfare; (4) In order to ensure the stable operation of combat equipment, the damping and energy absorption of armor still needs to be improved

Embodiment 1

[0042] A method for preparing an anti-penetration material, comprising the following steps:

[0043](1) The support layer is made of multi-layer carbon fiber woven fabrics pre-impregnated with resin and bonded together by hot pressing. The pre-impregnated resin used is epoxy resin, and the mass ratio of epoxy resin to the support layer is 30-40%. Under the conditions of 120-150° C. and pressure of 15-20 MPa, heat preservation and pressure-holding for 30 minutes to obtain a support layer with a thickness of 5 mm.

[0044] (2) on SiO 2 -Add ethanol to the STF system of the polyethylene glycol system to dilute, the dilution volume ratio is ethanol:STF=3:1, put the aramid fiber II woven fabric into the above solution for dipping treatment, take it out and put it under the condition of 60-100°C Dry for 8 hours to obtain the aramid fiber II / STF composite woven fabric.

[0045] Graphene is added in the epoxy resin, stir and disperse evenly first, then ultrasonic vibration 30min, af...

Embodiment 2

[0053] The difference between embodiment 2 and embodiment 1 is that SiO 2 -The dilution volume ratio of STF system and ethanol in polyethylene glycol system is 1:1.

Embodiment 3

[0055] The difference between embodiment 3 and embodiment 1 is that graphene is selected from graphene oxide.

[0056] Experiments show that SiO 2 -The anti-puncture effect of STF system and ethanol dilution volume ratio of polyethylene glycol system is 1:1 is better than 3:1; graphene oxide is better combined with fiber interface due to the presence of polar groups on the surface, and its mechanical properties are better superior to graphene.

Abstract

The invention discloses an anti-penetration material and a preparation method and application thereof.The anti-penetration material comprises an upper coating (1), a restraint layer (2), a ceramic layer (3), a supporting layer (4), an energy dissipation layer (5), an energy absorption layer (7) and a lower coating (8) from outside to inside, the energy dissipation layer (5) comprises a composite material A and a composite material B, the composite material A is a high-performance fiber-shear thickening fluid composite material, and the composite material B is a high-performance fiber-shear thickening fluid composite material. The composite material B comprises at least one of a high-performance fiber-graphene composite material and a high-performance fiber-graphene derivative composite material. According to the anti-penetration material, the composite armor is designed by comprehensively considering factors such as protection performance and maneuverability, the surface density and thickness of a protection structure can be effectively reduced, and penetration damage is limited within a small range.

Description

technical field [0001] The invention belongs to the field of protective armor, in particular to an anti-penetration material and its preparation method and application. Background technique [0002] With the continuous improvement of the penetrating ability of modern weapons, higher requirements are put forward for the protection of helicopter armor and tank armor, and the weight of bulletproof armor is also getting heavier. However, in order to ensure the mobility of combat equipment, the contradiction between the armor weight and its protection has become the primary problem that needs to be resolved. [0003] In order to achieve the effect of effective protection against bullet penetration, metal bulletproof armor needs to continuously increase the thickness of bulletproof steel, which will greatly sacrifice the mobility of combat equipment. Therefore, researchers have developed bulletproof armor of non-metallic materials. Non-metallic ceramic materials have been widely...
