摘要

摘要: 轻巧、可承载、抗侵彻一体化超结构相较于传统承载结构与披挂装甲，可有效减轻质量并提高空间利用率，在军事装备与国防设施中具有广阔的应用前景.该文基于陶瓷混杂点阵夹芯超结构，对比了超结构与传统波纹结构在三点弯曲载荷下的承载位移曲线，并通过实验研究了超结构在多点弹道冲击下的防护性能与抗侵彻机理.研究结果表明，陶瓷混杂点阵夹芯超结构在弯曲载荷下主要发生陶瓷脆性断裂、面板塑性断裂与胶层开裂等失效，其承载能力高于传统波纹结构.此外，该文还发现冲击位置与芯体类型影响超结构的抗多发特性，陶瓷混杂蜂窝芯体超结构的抗多发性能优于陶瓷混杂波纹芯体超结构.波纹结构在纵向对陶瓷缺乏约束，而蜂窝芯体对陶瓷的约束作用更强，从而可限制陶瓷损伤面积，使得抗侵彻性能随着冲击次数的增多而基本保持一致.

Abstract: Lightweight, load-bearing, and penetration-resistant integrated meta-structures have significant potential in military equipment and defense facilities, as they can effectively reduce weight and improve space utilization compared to traditional load-bearing structures and armors. Based on hybrid sandwich meta-structures, the load-deflection curves of the meta-structure and the traditional corrugated sandwich under 3-point bending loads were compared. The protective performance and energy absorption mechanism of the meta-structure under multiple ballistic impacts were experimentally studied. The research results indicate that, the hybrid sandwich meta-structure mainly experiences brittle fracture of ceramic, plastic fracture of face-sheets, and debonding of the adhesive layer under bending loads. Its load-bearing capacity is higher than those of traditional corrugated sandwiches. Furthermore, the study also reveals that the impact location and the lattice core type influence the multi-impact resistance of the meta-structure, with the honeycomb core demonstrating superior multi-impact resistance compared to the corrugated core. The corrugated sandwich lacks longitudinal constraints on the ceramic, while the honeycomb core provides stronger constraints on the ceramic, limiting the area of ceramic damage. As a result, the penetration-resistant performance remains relatively consistent as the number of impacts increases.
