Problems solved by technology

However, the weakness of fiber composite materials is also very prominent. On the one hand, in the face of transportation equipment and other protection, fiber composite materials are not rigid enough, and traditional metal materials are needed as support. Bulletproof and structural support can play a synergistic role. On the other hand, for Bullets of medium caliber and above with high kinetic energy and high hardness core, the thickness of the fiber laminate is required to be higher, and the impact deformation is large
Composite bulletproof panels made of fiber laminates and ceramics also face large impact deformation and cannot provide structural support.

Embodiment 1

[0111] Choose a square boron carbide ceramic with a side length of 50mm and a thickness of 5mm. Use a 0.2mm thick plain weave aramid cloth to package the ceramic. The packaging steps are:

[0112] Design the shape of the packaging cloth according to the shape of the ceramic. Take the ceramic facing surface as the front or the axial rotation center. The rotating ceramic is expanded laterally based on one of the sides, and then the two ceramics are centered on each expanded side. It is unfolded on both sides to design the shape drawing of the aramid cloth for packaging ceramics, and the cutting drawing of the aramid cloth for packaging is like Figure 5 As shown, 12-1 is the ceramic facing surface and the size is 50mm*50mm, and 11-1 is the side surface to avoid chamfering loss, and the size is 50mm*5.5mm;

[0113] according to Figure 5 The drawing, the cutting edge is parallel to the radial or weft direction of the aramid cloth, and the aramid cloth of the corresponding shape is cut;...

Embodiment 2

[0128] According to the method described in Example 1, the human body protection chest insert is prepared. The difference from Example 1 is that it uses a square boron carbide ceramic with a side length of 7mm, a 2mm thick titanium foam component with a porosity of 20%, and a 10mm thick ultra-high molecular weight. Polyethylene fiber laminate is used as the back sheet.

[0129] According to the method of Example 1, the surface density of the human body protection chest insert prepared in Example 2 of the present invention is 24kg / m 2 , The impact surface density is 35kg / m 2 ; Compared with products of the same level of protection, the areal density is reduced by 25%.

[0130] Use the Type 53 7.62mm armor-piercing incendiary bomb and test it in accordance with the "GA950-2011 V50 Test Method Test of Bulletproof Materials and Products". Its V50> 818m / s, three effective shots, all partially penetrated, and the height of the back protrusion is less than 20mm, which meets the requirement...

Embodiment 3

[0131] Example 3 Against the threat of 54 type 12.7mm*108mm API armor-piercing incendiary bomb

[0132] Choose a regular hexagonal boron carbide ceramic with a length of 83mm on the opposite side and a thickness of 13mm. Use a 0.2mm thick glass fiber cloth to package the ceramic. The package method is:

[0133] Design the shape of the packaging cloth according to the shape of the ceramic. Take the ceramic facing surface as the front or the axial rotation center. The rotating ceramic is expanded laterally based on one of the sides, and then the two ceramics are centered on each expanded side. It is unfolded facing both sides to design the shape drawings of the glass fiber cloth encapsulating ceramics, and the cutting drawings of the glass fiber cloth encapsulating Image 6 As shown, 12-1 is the ceramic facing surface, the size is 48mm*48mm, and 11-1 is the side. To avoid chamfering loss, the side size is 48mm*13.5mm; the side length of the regular hexagon with the opposite side lengt...

Abstract

The invention provides an ultra-light armor which comprises a ceramic layer component, a packaging layer, a foam titanium component and a back plate; the ceramic layer component is packaged by the packaging layer; the foam titanium component is arranged on the surface of the packaging layer; the back plate is arranged on the surface of the foam titanium component; the ceramic layer component is formed by splicing ceramic small blocks; and the packaging layer is made of fiber cloth. For the ultra-light armor provided by the invention, by using foam titanium as a novel material, the problems that too large damage area and too severe deformation of the back plate caused by the fact that an armor resists high-energy impact are solved, the overall areal density of an armor plate is greatly lowered, and the multi-bullet resistance is improved. The invention further provides a preparation method for the ultra-light armor.

Description

Technical field [0001] The invention relates to the technical field of armor, in particular to an ultralight armor and a preparation method thereof. Background technique [0002] At present, most of the mainstream bulletproof armors are made of metal materials, and there are also some non-metal composite materials. Metal bullet-proof armor has been developed for decades, and the products are mature and low-cost, generally high-strength, high-hardness average steel plate, aluminum alloy plate or titanium alloy plate, but its weakness is also obviously high surface density. [0003] Regardless of personal protection or vehicle equipment protection, its primary task is to protect against warheads or explosive fragments under ballistic impact. As weapons are upgraded or the level of ballistic threats faced by customers increases, higher requirements are placed on the protection capabilities of ballistic armor. At the same time, human body protection has higher requirements for lightwe...
