Novel composite UHPC projectile-resistant layer capable of resisting repeated attacks

Abstract

The invention discloses a novel composite UHPC projectile-resistant layer capable of resisting repeated attacks. The composite projectile-resistant layer is composed of three different UHPC structurallayers, wherein the top layer is a corundum sphere steel bar UHPC structure; the middle layer is a steel pipe UHPC dense arrangement structure; and the bottom layer is a UHPC air interlayer structure. The novel composite UHPC projectile-resistant layer has the three different efficiently-protective UHPC structures, and comprehensively reduces the catastrophic damage caused by war. Multilayer corundum spheres in the top layer can enable projectile fragments to continuously deflect so as to reduce the speed and destructive power of the projectile fragments and change original trajectories. Dense plum-shaped steel pipe UHPC in the middle layer provides continuous resistance, so that the projectile fragments continue to slow down and even stay in steel pipes. The UHPC air interlayer structurein the bottom layer diffuses blast waves carried by the projectile fragments or nuclear explosion while providing partial resistance so as to achieve the effect of reducing secondary hazards.

Description

technical field [0001] The invention belongs to the technical field of engineering protection, and in particular relates to a novel composite UHPC bullet-shielding layer resistant to repeated strikes. Background technique [0002] Along with the progress of scientific level, the various new bullet-shielding structures of present research and development have also possessed multiple functions, but most of them are bullet-shielding layers with a single function, which cannot effectively carry out safety protection in various situations. Most of the existing bullet-shielding structures are developed or improved bullet-shielding materials to increase the strength and reduce the degree of damage, or change the eroded trajectory of the bullet body to make it deflect, but its durability is often not strongly guaranteed, and its relatively simple The protection function often cannot meet the needs of modern warfare, and the protection against the shock waves attached to nuclear expl...
