Abstract

The invention discloses a titanium alloy-ceramic-PE composite bulletproof deck and a preparation method thereof, and belongs to the technical field of weaponry. The preparation method of the titaniumalloy-ceramic-PE composite bulletproof deck comprises the following steps that 1, titanium alloy powder and diamond particles are evenly mixed to prepare titanium alloy composite powder; 2, the titanium alloy composite powder is flatly laid on a graphite mold, then the graphite mold is covered with a carbon nanofiber toughened boron carbide ceramic chip, and a titanium alloy-ceramic composite deckis prepared through hot-pressing sintering; and 3, a PE plate with ultra-high molecular weight is bonded to the titanium alloy-ceramic composite deck, prepared in the step 2, to prepare the titaniumalloy-ceramic-PE composite bulletproof deck. The prepared composite bulletproof deck is good in overall bonding performance and highly resistant to armor-piercing bullets and armor-piercing incendiaries.

Description

technical field [0001] The invention relates to a technology in the field of weapon equipment, in particular to a titanium alloy-ceramic-PE composite bulletproof deck and a preparation method thereof. Background technique [0002] Boron carbide has excellent properties such as low density, high hardness, strength, and elastic modulus, and is more and more widely used in the field of bulletproof armor. However, its flexural strength and fracture toughness are low, and its brittleness is relatively high, which limits the application of boron carbide ceramics. [0003] Chinese invention patent application CN103727842A discloses a fiber / ceramic / metal composite bulletproof plate and its preparation method. The method prepares a titanium alloy frame by laser welding, and uses an adhesive to fix the ultra-high molecular weight polyethylene plate on the titanium alloy frame. In the cavity, an adhesive is used to connect the carbon fiber layer and the ceramic layer, and the connecti...
