Example Embodiment

[0012] Example 1

[0013] The surface layer 10 is a 1mm thick neoprene rubber cloth with a surface density of 0.14g / cm 2 ; The rubber layer 20 is 4mm natural rubber with an areal density of 0.46g / cm 2 ; The ceramic layer 30 is a corundum ceramic column with a height of 18mm, with hemispherical surfaces at both ends, and an areal density of 5.24g / cm 2 ; The resistance layer 40 is a 2mm thick TC4 titanium alloy plate with an areal density of 0.89g / cm 2 . The surface density of the whole board after compounding is 6.7~6.9g / cm 2 , Which is 67~69Kg / m 2 , The thickness of the whole board is 25~26mm, the whole board is a square flat plate, and the length and width are both 150mm.

Example Embodiment

[0014] Example 2

[0015] The anti-collapsing layer 10 is a 2mm thick polycarbonate board with an areal density of 0.1g / cm2; the rubber layer 20 is 3mm non-vulcanized rubber with an areal density of 0.34g / cm2; the ceramic layer 30 is a 16mm thick boron carbide board with an areal density of 3.82 g / cm2; the resistance layer 40 is a 3mm thick carbon fiber composite material board with an areal density of 0.2g / cm2.

Abstract

The invention discloses a self-healing bulletproof composite material which is characterized by comprising a four-layer structure which comprises a surface layer, a rubber layer, a ceramic layer and a resistant layer. The surface layer is composed of a chloroprene rubber composite material or a polycarbonate film material, the rubber layer is composed of natural rubber or non-vulcanized rubber, the ceramic layer comprises corundum or silicon carbide or boron carbide components, the resistant layer is composed of TC4 titanium alloy or a fiber composite material, the layers are connected in an adhesive mode through adhesives, and the surface density is 40-75Kg/m2. The bulletproof material of a composite structure has the advantages of being low in weight, capable of being repaired, capable of healing automatically and resistant to impact of multiple bullets, can serve as a protective material against medium-and-small caliber armor-piercing incendiaries with the caliber of 7.62mm or above, and can be used for manufacturing bulletproof helmets and naval vessel decks.

Description

technical field [0001] The patent of the present invention relates to a bulletproof composite material, in particular to a composite structure bulletproof material with self-healing function. Background technique [0002] Military strategists have attached great importance to armor since ancient times, because it is an important measure to effectively protect oneself and strike the opponent effectively in war. Metal material is the most important material of modern armor. From ordinary steel armor to high-hardness steel armor, double-hardness steel composite armor, and even titanium alloy armor, the protection ability has been continuously improved. Metal material armor plays an important role in the protection of tanks, armored vehicles, warships, etc. In the 1950s, lightweight composite bulletproof armor appeared, such as fiber composite armor and ceramic composite armor, which came out one after another and continued to develop. New material technology has a wide range...
