Composite armor structure with inverted cone, manufacturing method and mounting method

Abstract

The composite armor structure comprises an upper panel, the cone located on the lower surface of the upper panel, a lower panel, a kinetic energy absorption layer located on the upper surface of the lower panel and a packaging shell wrapping the periphery, the upper panel and the cone are of an integrally-formed structure, and the cone head faces the lower panel; a gap layer used for guaranteeing sufficient deflection of a penetration body is arranged between the kinetic energy absorption layer and the cone of the upper panel in a spaced mode. According to the armor structure of the combined bulletproof mechanism of yaw induction, gap deviation promotion and tail end energy absorption, a cone arranged downwards starts to induce a missile body to yaw, and a gap layer is arranged in the middle to amplify the yaw so as to further promote a trajectory to completely yaw and increase the stress area; finally, a kinetic energy absorbing layer is arranged to prolong a projectile body path and effectively absorb residual kinetic energy of the projectile body.

Description

technical field [0001] The invention relates to an armor structure suitable for armor protection and ship building, in particular to a composite armor structure with an inverted cone, a manufacturing method and an installation method. Background technique [0002] In the prior art, a lot of research has been carried out on the phenomenon of high-speed penetration, so as to reduce the damage of the protected structure and resist the penetration of high-speed projectiles. With the continuous development of technology and the improvement of protection requirements, the impact resistance of traditional homogeneous armor represented by a single metal is far from meeting the demand, so various new composite materials and composite armor structures continue to emerge. [0003] Composite armor structure is a heterogeneous protective structure composed of more than two layers of protective materials with different properties. It can be mainly divided into three categories: metal and ...

Problems solved by technology

For example, in patent CN109178195A, a number of oblique ribs parallel to each other are evenly distributed on the inside of the upper panel and the lower panel. Although the impact direction of the projectile can be changed to a certain extent, the parallel ribs can only make the projectile deflect to one side, which is not conducive to the structure. The overall protection; the ribs of the protective plate are wrapped by the core material, which will restrain the deflection of the projectile to a certain extent, and cannot maximize the deflection effect of the projectile

[0007] It can be seen from the above that although the current composite armor structures have various types and functions, there are still many limitations and shortcomings in each technical solution.
