Description

Technical Field

[0001] This invention relates to the field of protective equipment technology, and in particular to a three-dimensional stealth armor structure. Background Technology

[0002] The pursuit of lighter, more protective, and more manufacturable materials and structures has always been a core goal and direction in the field of protective equipment technology. Stealth armor is generally used in weaponry such as aircraft, ships, armored vehicles, and even fortifications. Its surface is coated with stealth paint or has stealth patches bonded to it, while the internal gaps are sprayed with stealth paint or have stealth patches bonded to it to achieve stealth against visible light, infrared, radar, and laser light. The goal is to meet both protective and stealth performance requirements while ensuring the lowest possible increase in mass, minimizing the impact on the weaponry's mobility and survivability. Therefore, there is a need to invent a new three-dimensional stealth lightweight composite armor structure. Summary of the Invention

[0003] The purpose of this invention is to provide a three-dimensional stealth armor structure that, while ensuring both protective and stealth performance, minimizes armor mass and reduces the impact on the mobility and survivability of weapons and equipment.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] A three-dimensional stealth armor structure includes multiple sets of slatted armor plates arranged sequentially. The multiple sets of armor plates are arranged in parallel and spaced apart. One side of each armor plate is fixed to a plane or an inclined plane arranged at an angle to the body being defended. A box-shaped connector is fixed in the gap between each pair of armor plates. The box-shaped connector is located at both ends of the gap between the armor plates and connects the slatted armor plates into a whole.

[0006] Furthermore, the thickness of the armor plate is 5mm to 20mm, the number of armor plates is 2 to 6 sets, and the gap between each pair of armor plates is 5mm to 20mm.

[0007] Furthermore, when the armor plate is fixed on the inclined surface of the body being defended at an angle, the two armor plates are spliced ​​together at an angle to form a V-shaped structure on opposite sides, and the inclination angle α of the armor plate is 10 to 30 degrees.

[0008] Furthermore, the armor plate is made of any one of armor steel, glass fiber reinforced epoxy resin composite material, or carbon fiber reinforced epoxy resin composite material, or the armor plate is a ceramic reinforced ballistic composite plate.

[0009] Furthermore, when the armor plate is a ceramic-reinforced ballistic composite plate, its structure is a sandwich structure of two layers of armor steel plates, with a ceramic plate fixedly installed between the two layers of armor steel plates. The ceramic plate is composed of several ceramic units spliced ​​together; the armor steel plates and the ceramic plate are fixedly connected by adhesive.

[0010] Furthermore, the thickness of the ceramic plate is 3mm to 18mm, and the thickness of the armor steel plate 1 is 1mm to 6mm.

[0011] Furthermore, the cross-section of the box-shaped connector is a hollow square or rhombus.

[0012] Furthermore, when the cross-section of the box-shaped connector is prismatic, its acute angle β is 60 to 80 degrees.

[0013] Furthermore, the outer and inner walls of the armor plate, as well as the surface of the box-shaped connector, are all covered with stealth coating or stealth patch; the thickness of the stealth coating or stealth patch is 1-3 mm.

[0014] Furthermore, the multiple assembled decks are fixed to each other by bolts; the armor steel plates and ceramic plate box-shaped connectors are connected by adhesive.

[0015] The beneficial effects of this invention: This invention provides a three-dimensional stealth armor structure that, compared to traditional armor, imparts stealth capabilities to the armor structure while maintaining protective performance. The slatted armor plates, connected by box-shaped connectors, create gaps between the slats, which, upon impact by projectiles, disrupt the penetrating projectiles, further improving the product's protective performance. Furthermore, its lightweight nature and excellent ballistic resistance allow for the deflection of projectiles in the incident direction; even if the projectile is not deflected, excellent protective performance is still achieved. This invention can meet the protection and stealth performance requirements of various types of weapons and equipment, such as aircraft, ships, armored vehicles, and even fortifications, while simultaneously ensuring the mobility and survivability of these weapons and equipment.

[0016] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0017] Figure 1 This is a structural diagram of a three-dimensional stealth armor structure according to the present invention.

[0018] Figure 2 This is a cross-sectional view of a three-dimensional stealth armor inclined structure according to the present invention.

[0019] Figure 3 This is a schematic diagram of the structure of the present invention arranged on the defended object. Detailed Implementation

[0020] like Figure 1 and Figure 2 The diagram shows a three-dimensional stealth armor structure, comprising multiple sets of strip-shaped armor plates arranged sequentially. These armor plates are parallel and spaced apart. One side of each armor plate is fixed to a plane or an angled slope of the protected object, which can be weaponry or fortifications. A box-shaped connector 3 is fixedly installed in the gap between every two armor plates. The box-shaped connector 3 is located at both ends of the gap and connects the strip-shaped armor plates into a single unit. The box-shaped connector 3 serves to securely connect the two armor plates.

[0021] Preferably, in conjunction with the above scheme, the thickness of the armor plate is 5mm to 20mm, the number of armor plates is 2 to 6 sets, and the gap between each pair of armor plates is 5mm to 20mm. This size of gap will produce a gap effect. When the projectile penetrates two materials of different densities, the projectile will no longer travel perpendicularly and will deflect at an angle. The deflection of the projectile is equivalent to an increase in penetration thickness, which is more conducive to improving the protective performance of the armor.

[0022] Preferably, in combination with the above scheme, in order to achieve the best projectile offset effect, such as Figure 2 and Figure 3 As shown, when the armor plates are fixed to the inclined surface of the protected object at an angle, the two armor plates are joined at an angle to form a V-shaped structure on opposite sides. This angle can also be determined according to the angle of the protected object. The inclination angle α of the armor plates is 10-30° (the angle between the armor plate and the horizontal plane of the incoming projectile). Even if the projectile does not deflect upon entering the armor plate, the angle effectively increases the thickness of the armor plate, thereby improving its ballistic resistance.

[0023] Preferably, in conjunction with the above scheme, to ensure sufficient ballistic performance, the armor plate is made of any one of the following: single-layer armor steel, glass fiber reinforced epoxy resin composite material, or carbon fiber reinforced epoxy resin composite material; or the armor plate is a multi-layer ceramic-reinforced ballistic composite plate. The glass fiber reinforced epoxy resin composite material can be provided by Chongqing International Composite Materials Co., Ltd. or Taishan Glass Fiber Co., Ltd., and the carbon fiber reinforced epoxy resin composite material can be provided by Toray Industries, Inc. or Zhongfu Shenying Carbon Fiber Co., Ltd.

[0024] Preferably, in combination with the above scheme, in order to provide better ballistic performance, when the armor plate is a ceramic-reinforced ballistic composite plate, its structure is a sandwich structure of two layers of armor steel plates 1, with a ceramic plate 2 fixedly installed between the two layers of armor steel plates 1. The ceramic plate 2 is spliced ​​together from several ceramic units. The connection gap between the ceramic units should not be too large, as this will affect the ballistic performance. The armor steel plates 1 and ceramic plates 2 are fixedly connected by adhesive, and can be fixedly bonded into a whole by polyurethane structural adhesive.

[0025] Preferably, in conjunction with the above scheme, to achieve the optimal match between thickness, weight, and ballistic performance, the material of the ceramic plate 2 is any one of alumina ceramic, silicon carbide ceramic, boron carbide ceramic, and silicon nitride ceramic. The thickness of the ceramic plate 2 is 3mm to 18mm, and the thickness of the armor steel plate 1 is 1mm to 6mm. Alumina ceramic, silicon carbide ceramic, boron carbide ceramic, and silicon nitride ceramic can all be provided by Yangzhou Beifang Sanshan Industrial Ceramics Co., Ltd. The armor steel can be provided by Beijing Iron and Steel Design and Research Institute Co., Ltd.

[0026] Preferably, in combination with the above scheme, in order to achieve lightweight design and better fit and fix with the armor plate, the cross-section of the box-shaped connector 3 is a hollow square or prism.

[0027] Preferably, in combination with the above scheme, in order to better match the inclination of the armor plate and ensure the firmness of the connection, when the cross-section of the box-shaped connector 3 is prismatic, its acute angle β is 60 to 80°.

[0028] Preferably, in conjunction with the above scheme, to achieve a better stealth effect, the outer and inner walls of the armor plate, as well as the surface of the box-shaped connector 3, are all covered with stealth coating or stealth patches; the thickness of the stealth coating or stealth patches is 1-3 mm. The stealth coating or patches can be provided by Shaanxi Huaqin Technology Industry Co., Ltd.

[0029] Preferably, in conjunction with the above scheme, to increase the firmness of the fixed connection, the multi-assembly decks are fixedly connected to each other by bolts 4; the armor steel plate 1 and the ceramic plate 2 box-shaped connector 3 can be fixedly connected by polyurethane structural adhesive. The above-mentioned polyurethane structural adhesive can be prepared by mixing Macroplast UK 8103 and Macroplast UK 5400 two-component polyurethane adhesives in a weight ratio of 4:1.

[0030] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, fall within the protection scope of the present invention.
