Background
The development trend of armored vehicles is 'light-weight', namely, under the premise of ensuring the attack and protection capability, the self weight is obviously reduced so as to improve the maneuverability. Currently, lightweight armored vehicles mainly consider the threat of small armor piercing projectiles (APIs) and high-speed fragmentation, such as fragmentation resulting from 60-25 m distance explosions of class 3, 4 threat of 7.62-14.5 mm caliber and 155mm caliber projectiles in class 5 protection classes of the STAN4569 standard. The side and rear base armor of the existing light armored vehicle is weak and cannot reach the protection level, so that the thickness of the armor is increased and the maneuverability of the armor is affected. Therefore, in order to achieve "light weight" of armored vehicles, light weight armor must be developed to substantially reduce the armor dead weight. Of the armors of existing light-weight armored vehicles, ceramic composite armors have the best resistance to elasticity.
The ceramic composite armor is applied mainly in the form of a relatively hard ceramic face plate, a metal or fiber composite material with good toughness as a back plate, and the two are usually bonded by an adhesive. The structure has the significance that the respective advantages of the two materials can be fully exerted, namely, the high hardness and the high elastic modulus of the ceramic material are utilized to meet the penetration resistance required by armor; the toughness and ductility of metal or fiber composite materials are utilized to meet the impact resistance and anti-caving capability required by armor, and the ceramic composite armor is the light composite armor with the simplest structure and the most research at present, and is formed by bonding a ceramic face plate and a metal or composite material back plate. The panel is usually made of AL2O3, siC, B4C ceramics and the like; the backboard adopts metal or composite materials with good toughness, such as steel, aluminum alloy, kevlar, PE composite materials and the like. In the ceramic composite armor, the packaging plays a role of connecting various materials, and the ceramic plate and the backboard in the ceramic composite armor are integrally packaged, so that the anti-elastic performance of the ceramic and the backboard is fully exerted.
The traditional ceramic composite armor is formed by bonding a ceramic panel and a back plate in a simple material superposition mode, bonding glass fiber cloth on the upper surface and the lower surface of a composite armor plate by using an epoxy resin adhesive, and heating and solidifying the glass fiber cloth to bond the glass fiber cloth on the surface of the armor plate to form the ceramic composite armor outer surface package.
