Composite protective armor with flame-retardant self-repair structure

Abstract

The invention discloses a composite protective armor with a flame-retardant self-repair structure, relates to the technical field of protective armors, and specifically relates to a self-repair armorplate and a flame-retardant inner-layer plate. A high-strength spring is connected to the bottom of the self-repair armor plate; the flame-retardant inner-layer plate is fixed to the bottom end of thehigh-strength spring, and a liquid adding port is formed in the inner side surface of the flame-retardant inner-layer plate; a sealing cap is installed in the liquid adding port; a liquid adding chamber is formed in the flame-retardant inner-layer plate; support columns are welded to the top and the bottom of the inner wall of the liquid adding chamber; and liquid permeation holes are formed in the upper surface and the lower surface of the flame-retardant inner-layer plate separately. According to the composite protective armor with the flame-retardant self-repair structure, a memory metal lining is made from memory metal, and has the characteristic of recovering to the original shape at a temperature which is greater than a memory temperature; and through the arrangement, in the case that an armor plate body is damaged and deformed, only a new armor plate body needs to be replaced, and metal plate working does not need to be carried out, so that increasing for a repair speed and reduction for time needed for repair are benefited.

Description

technical field [0001] The invention relates to the technical field of protective armor, in particular to a composite protective armor with a flame-retardant self-repairing structure. Background technique [0002] The development of armor has been accompanied by the development of technology and new materials, and its protective performance has been greatly improved. During World War I, the tactical role of armored vehicles began to manifest. Light armored vehicles were originally required to resist pistol bullets and general rifle bullets. Up to now 12.7mm armor-piercing projectile. [0003] The surface armor plate of existing armored vehicles cannot restore the original structure by itself, resulting in a longer maintenance cycle after the armor plate is deformed and broken, and the armored vehicle often burns on the surface of the car body after being attacked by shells, which is easy to damage the interior of the car body Threat to the safety of personnel.

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a composite protective armor with a flame-retardant self-repairing structure, which solves the problem that the surface armor plate of the armored vehicle proposed in the above-mentioned background technology cannot restore its original structure by itself, resulting in deformation and fragmentation of the armor plate Afterwards, the maintenance cycle becomes longer, and the surface of the armored vehicle often ignites flames after being attacked by shells, which is likely to pose a threat to the life safety of the personnel inside the vehicle body.
