Novel composite UHPC projectile-resistant layer capable of resisting repeated attacks
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.
本发明公开了一种抗多次重复打击的新型复合UHPC遮弹层。该复合遮弹层共有三种不同的UHPC结构层复合而成，顶层为刚玉球钢筋UHPC结构，中层为钢管UHPC密排列结构，底层为UHPC空气夹层结构。本发明的新型复合UHPC遮弹层具有三层不同的高效防护UHPC结构，全面降低战争造成的灾难性危害。顶层的多层刚玉球可以使弹片发生连续的偏转，降低弹片的速度和破坏力并改变原有弹道；中间层的密集梅花状钢管UHPC提供持续的阻力使得弹片继续降低速度甚至停留在钢管内；底层的UHPC空气夹层结构提供部分阻力的同时将弹片或核爆携带而来的爆炸冲击波发生扩散，达到减少次生危害的作用。
