Description

Technical Field

[0001] This invention belongs to the field of composite material technology and relates to a method for preparing armor protection materials, specifically a method for preparing a high-temperature resistant bulletproof composite plate for armored vehicles and the high-temperature resistant bulletproof composite plate. Background Technology

[0002] Armored vehicles often encounter various harsh environmental conditions, such as high temperatures, flames, and explosions. High-temperature resistant ballistic composite plates maintain stable physical and chemical properties under high-temperature environments, ensuring that armored vehicles retain good protective capabilities even in extreme conditions. These plates effectively resist threats in high-temperature environments. The composite plates utilize multiple layers of different materials to form a structure with excellent ballistic performance. These materials include high-strength ceramics, aramid fibers, and carbon fibers, which effectively absorb and disperse the impact energy of bullets or shrapnel, thus protecting the safety of the occupants and equipment inside the vehicle.

[0003] Despite significant advancements in the military field regarding ballistic composite armor plating for armored vehicles, several shortcomings remain. Firstly, current composite materials often struggle to achieve an optimal balance between weight and protective performance. While high-strength composites offer superior protection, their increased weight reduces the vehicle's mobility and fuel efficiency.

[0004] Secondly, the high production cost of bulletproof composite plates limits their widespread application. The manufacturing process of composite materials is complex, requiring advanced equipment and technology, which keeps production costs high. Furthermore, the repair and replacement of composite materials are relatively difficult and expensive, adding an extra burden to maintenance in both wartime and peacetime.

[0005] Furthermore, existing bulletproof composite panels also have some issues regarding environmental adaptability. For example, the performance of the composite material may be affected under extreme temperature conditions, leading to a decrease in protective capabilities. In addition, composite panels may experience aging and fatigue during long-term use, thereby affecting their structural integrity and protective effectiveness.

[0006] To overcome these shortcomings, it is necessary to develop a new type of composite material, and to research and develop lighter, stronger, and more heat-resistant composite materials to improve the protection and mobility of armored vehicles, so that more units can be equipped with advanced armor protection systems and improve overall defense capabilities.
