Problems solved by technology

However, most of the studies are based on the theme of sandwiching rectangular ceramic sheets between metals or non-metals. The layers are mainly bonded with organic adhesives, and the interface bonding strength is low, which affects the ballistic performance.
In addition, due to the complexity of the structure of ceramic / metal composite bulletproof materials and the physical process of bullet strikes, only the current numerical simulation technology and laboratory experiments cannot fully reflect the authenticity of this physical process.

Embodiment Construction

[0017] First prepare the materials, the required materials include: processed by brazing or wire cutting figure 1 The honeycomb core plate (3) shown; processing image 3 As shown in the ceramic chip (4), the ceramic chip can be made into a flat shape or a curved shape, and its size should match the size of the honeycomb holes on the honeycomb core board; the metal face plate (1) and the metal back plate (6) Bulletproof steel plates that have been heat-treated after cold rolling should be used; Ag72Cu metal brazing filler metals and epoxy resin-based high-strength structural adhesives used for interface connections.

[0018] followed by assembly and welding, the structure is as Figure 4 and Figure 5 As shown, the specific process is: the Ag72Cu metal brazing material is sandwiched between the metal back plate (6) and the honeycomb core plate (3), placed in a vacuum furnace, and heated at 1×10 -2 Under Pa vacuum, heat to 845°C, keep warm for 45 minutes for brazing, take out...

Abstract

In the invention, the composite bullet-proof armour plate consists of a metal panel, a honeycomb core board, a ceramic wafer core and a metal rear panel bonded with the metal brazing layer via the organic adhesive layer. The preparing method is that using the brozing and the line-cutting method are finished the honeycomb core board and the plain or curved ceramic wafer core, whose size must fit in that of the honeycomb hole of the honeycomb core board. The panel and the rear panel must be made of the bullet-proof steel plate through heat treating after cold rolling. The Ag72Cu metal brazing material and the epoxy resin group high strength structural sizing for connecting the interface are assembly welded.

Description

technical field [0001] The invention belongs to the technical field of structural functional materials, and in particular provides a steel honeycomb ceramic sandwich composite bulletproof armor plate and a preparation method thereof. Background technique [0002] Many scholars at home and abroad have carried out detailed research on the relevant theories, protection mechanisms, preparation processes, analysis methods, numerical simulation and structural optimization of ceramic / metal composite armor. The research content involves the bulletproof mechanism of ceramic / metal composite armor, the type of ceramic / metal, the thickness ratio, the arrangement method, the influence of ceramic prestress, and the simulation method adopted. However, most of them are researched on the theme of sandwiching rectangular ceramic sheets between metals or non-metals. The layers are mainly bonded with organic adhesives, and the interface bonding strength is low, which affects the ballistic perfo...
