Abstract

The invention discloses a ceramic-titanium alloy-PE composite bulletproof deck and a preparation method thereof, and belongs to the technical field of weapon equipment. The preparation method of the ceramic-titanium alloy-PE composite bulletproof deck comprises the following steps: S1, mixing titanium alloy and surface-aluminized carbon nanofibers evenly, obtaining titanium alloy composite powder;S2, laying the titanium alloy composite powder on a graphite die, then, covering with a carbon nanofiber toughened boron carbide ceramic chip, and performing hot pressing and sintering to obtain a ceramic-titanium alloy composite deck; S3, adhering a PE board having ultra-high molecular weight with the ceramic-titanium alloy composite deck prepared in the step S2, and obtaining the ceramic-titanium alloy-PE composite bulletproof deck. The composite bulletproof deck prepared by the method of the invention has good overall associativity, and has high capability of resisting an armor-piercing bullet and an armor-piercing incendiary.

Description

technical field [0001] The invention relates to a technology in the field of weapon equipment, in particular to a ceramic-titanium alloy-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...
