▎ 摘 要
NOVELTY - The electromagnetic shielding penetration-preventing material has an upper coating (1), a restraint layer (2), a ceramic layer (3), an electromagnetic shielding layer (4), a second fibre composite layer (6) and a lower coating (7), which are arranged form outside to inside. The electromagnetic shielding layer has n-first fibre composite layers (41) and an m-aramid fiber honeycomb cardboards (42) bonded between the first fiber composite layers, where n is larger than m and n, m are positive integer USE - Electromagnetic shielding anti-penetration material for use in a bullet-proof device (claimed) for helicopter armors and tank armors. ADVANTAGE - The anti-penetration material is a composite armor designed by comprehensively considering factors such as protection, maneuverability and electromagnetic shielding property. It can reduce the surface density and thickness of the protective structure, and has a certain electromagnetic shielding performance, and can limit the penetration damage in a small range. The electromagnetic shielding layer has high shielding efficiency, wider shielding frequency band and lighter weight compared with a single-layer electromagnetic shielding structure. The conductive filler of the first fiber composite layer can be adjusted according to protection requirements, and the flexibility is better. The rubber layer is introduced into the anti-penetration material laminated structure, and the cord fabric is arranged in the anti-penetration material laminated structure to serve as a supporting framework, so that the damping energy absorption performance of the whole armor is improved. The impact generated by the kinetic energy release of the projectile can be better absorbed, and the operation stability of the combat equipment is ensured. The restraint layer is mainly used for preventing the ceramic layer from being integrally cracked and broken pieces from flying out, and the continuous penetration and destruction resisting capability of the armor is improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the electromagnetic shielding penetration-preventing material. DESCRIPTION OF DRAWING(S) - The drawing shows of an electromagnetic shielding anti-penetration material.
