Embodiment 1

[0025] This embodiment relates to a preparation method of bulletproof composite armor, comprising:

[0026] Step 1, you need 44g of B according to a single ceramic piece 4 C powder (Saifu Nano Technology) and 4.4g nano-carbon fiber (Suzhou First Element CNTcr), after mixing the two raw materials evenly, put them into a regular hexagonal mold with a height of 50mm and a thickness of 10.6mm, and undergo continuous automatic plasma Discharge sintering, the equipment used is Dr. FRITSCH DSP500 from Germany, the heating rate is 200°C / min, 50Mpa, 1800°C for 10 minutes, and a sufficient number of regular hexagonal boron carbide ceramic sheets are produced. The obtained regular hexagonal boron carbide ceramic sheets are high 50mm, thickness 8mm;

[0027] Step 2, the above-mentioned boron carbide ceramic sheet and copper foil with a thickness of 15 μm and a purity of >99% are combined according to figure 1 spliced ​​into the base metal, and then placed in a hot-pressing mold with the...

Abstract

The invention discloses a bulletproof composite armor and a manufacturing method thereof, and belongs to the technical field of ceramic and metal based composite material preparation. The manufacturing method for the bulletproof composite armor comprises the following steps: step 1 of uniformly mixing B4C powder with nano carbon fibers to obtain a mixture, putting the mixture into a regularly hexagonal mould, and quickly sintering the mixture into regularly hexagonal ceramic sheets through plasma discharge sintering; step 2 of splicing the regularly hexagonal ceramic sheets into a ceramic basematerial, filling splicing seams with micro-level copper foils, and performing vacuum hot-pressing sintering to obtain a ceramic deck; and step 3 of performing hot-isostatic pressing compounding on the ceramic deck and a bulletproof back board to obtain the bulletproof composite armor. The high-toughness composite ceramic bonded by the copper based metal material is compounded with the bulletproof back board to manufacture the bulletproof composite armor, so that multi-time impact resistance ability of armor-piercing bullets and armor-piercing incendiary ammunitions of the composite armor isgreatly improved.

Description

technical field [0001] The invention relates to a technique in the field of organic chemistry, in particular to a bulletproof composite armor and a preparation method thereof. Background technique [0002] The excellent properties of boron carbide make it more and more used in various industries. For example, a Chinese invention patent application with application number CN200910180582.5 discloses a composite ceramic, which increases the hardness of boron carbide ceramics by compounding boron carbide with carbon fibers; although the hardness of boron carbide ceramics is improved by compounding with other materials , but it is still difficult to achieve the bulletproof effect. [0003] The Chinese invention patent application with application number 200510086629.3 discloses a preparation method of steel honeycomb ceramic sandwich composite bulletproof armor. The method uses bulletproof steel plates to prepare honeycomb, fills ceramic chips, and glues and brazes to form compo...
