中文摘要:
      目的 根据仿生学原理,借鉴鳞甲类生物柔性拼接模式,设计出由碳化硼陶瓷和超高分子量聚乙烯(UHMWPE,PE)背板复合而成的仿生鳞片式拼接柔性防护结构,以提高防护装备的灵活性和抗多发弹性能。方法 首先通过高温热压成形工艺制备出复合鳞片,然后采用95式5.8 mm钢芯弹进行侵彻试验,最后结合有限元仿真对侵彻过程中的弹击损伤机制和能量耗散形式进行分析。结果 弹丸侵彻导致复合鳞片的陶瓷层发生了严重的碎裂现象,PE背板发生了类圆状凹陷变形,但未被穿透;单次弹击损伤范围被限制在弹击鳞片及其相邻鳞片附近,未形成大面积损伤,表现出优异的抗多发弹性能;弹丸的能量通过弹击鳞片扩散到与其相邻的鳞片上,降低了弹丸对弹击鳞片的损伤,提高了柔性结构的极限抗单发弹性能。结论 仿生鳞片式拼接柔性结构能够有效抵御95式5.8 mm钢芯弹的侵彻,具备柔性的同时还具有优异的抗多发弹性能,可应用于新一代单兵及武器装备的小口径枪弹防护装甲。
英文摘要:
      The work aims to design a spliced flexible protective structure composed of boron carbide ceramics and ultra-high molecular weight polyethylene (UHMWPE, PE) based on the principles of bionics with the flexible splicing mode of pholidota creators as a reference, so as to improve the flexibility and resistance to multiple rounds of protective equipment. Firstly, composite scales were prepared through high-temperature hot pressing molding process, and then shooting tests were conducted with a 95-type 5.8 mm steel core bullet. Finally, finite element simulation was used to analyze the mechanism of bullet damage and energy dissipation during the shooting process. The shooting of the bullet resulted in severe fragmentation of the ceramic layer of the scales, as well as circular deformation of the PE back plate, but it was not penetrated. The damage range of a single shot was limited to the vicinity of the shot scale and other adjacent scales, but no large-scale damage was formed, demonstrating excellent resistance to multiple rounds. The energy of the bullets diffuses through the shot scales to other adjacent scales, reducing the damage effect of the bullet on the shot scales and improving the ultimate single shot resistance performance of the flexible structure. The biomimetic scale spliced flexible structure can successfully resist the shooting of Type 95 5.8 mm steel core bullets, while possessing flexibility and excellent resistance to multiple rounds. It can be applied to the small caliber ammunition protective armor of the new generation of individual soldiers and weapons equipment.
