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...
