Embodiment 1

[0026] The preparation method of the present embodiment comprises the following steps:

[0027] Step 1. Cut the Ti-5322 titanium alloy plate with a thickness of 1.0mm into (250mm±1mm)×(300mm±1mm) (width×length) titanium alloy small pieces, and use a mold press to make the titanium alloy small pieces The plate is stamped into a multi-curved plate as the bombardment panel, and the titanium plate with a thickness of 0.4mm±0.05mm is cut into (265mm±1mm)×(315mm±1mm) (width×length) titanium small plates, and the mold press is used The titanium small plate is stamped into a multi-curved plate as a back plate; the periphery of the back plate has bending edges of equal height, and the bending edge rushes to the convex surface of the back plate, and the height of the bending edge is equal to the total height of the insert plate. The thickness is equal; the size of the bombardment face plate and the back plate is the same; the strength of the Ti-5322 titanium alloy plate is 1100MPa, and ...

Abstract

The invention discloses a preparation method of a novel composite bulletproof inserting plate. The preparation method comprises the steps that 1, a titanium alloy plate or a titanium plate is stampedinto a multi-curved plate to serve as a bullet-facing panel, and the titanium plate is stamped into the multi-curved plate to serve as a back plate; 2, aramid fiber cloth is cut into aramid fiber cloth pieces; 3, ultra-high molecular weight polyethylene prepreg is pressed into a polyethylene plate; 4, the aramid fiber cloth pieces are adhered to the convex surface of the polyethylene plate to forman aramid fiber cloth piece transition layer, ceramic is adhered to the aramid fiber cloth piece transition layer, then the aramid fiber cloth pieces are taken and adhered to the ceramic to form an aramid fiber cloth piece anti-cracking layer, and the polyethylene plate is solidified to obtain an inner core; and 5, the inner core is placed in the back plate, and the bullet-facing panel is sealedon the back plate, vacuumizing, welding and sealing are conducted, and then the bullet-proof inserting plate is obtained. According to the preparation method, the bullet-facing panel and the back plate are vacuumized and sealed, a waterproof, ultraviolet-proof, corrosion-resistant and oxidation-resistant enclosed protective space is formed around the inner core, erosion of sunlight and a humid environment to the aramid fiber, the ceramic and the ultra-high molecular weight polyethylene material of the inner core are avoided, and the service life of the bulletproof inserting plate is greatly prolonged.

Description

technical field [0001] The invention belongs to the technical field of bulletproof board preparation, and in particular relates to a preparation method of a novel composite bulletproof board. Background technique [0002] With the advancement of modern bulletproof technology and the popularization and application of soft bulletproof vests, in order to better ensure the safety protection level of individual soldiers, the insert-type composite bulletproof inserts in the standard equipment of single units have become more and more common. As a reinforced product of individual protective equipment, bulletproof inserts are usually used in conjunction with bulletproof vests. Generally, ceramics are used as panels, high-performance fibers and matrix composites are used as backplanes, and viscous polymers are used in the middle to bond and compound. The outside is made of high-strength cloth wrapping. In addition to being relatively thick and heavy, this type of composite material ...
