摘要

为提高陶瓷基复合材料在轻质装甲结构设计中应用的可行性，研究陶瓷基复合材料在抵抗弹体撞击时的表面驻留性能，进而探索其抗弹性能，旨在丰富和完善陶瓷基复合装甲材料的抗弹机理。采用数模模拟方法对弹体撞击SiC-Al陶瓷基复合材料表面驻留过程开展了深入研究，探索了复合材料的表面驻留行为，对比分析了复合材料和陶瓷材料表面驻留过程中应力水平和损伤演化过程。结果表明：复合材料表面驻留耗能为845J，比B4C、SiC、AD99 Al2O3陶瓷材料分别提高约46.0%、30.2%、35.7%；完全损伤的复合材料仍具有较一般陶瓷材料更高的承载能力，延长其驻留持续时间；复合材料损伤演化形式与陶瓷材料差异较大，导致损伤耗能占总驻留耗能的比例达到23.9%，比陶瓷材料提高了2倍多。

Abstract

With the purpose of increasing application value and revealing the ballistic mechanism of ceramic matrix composites

it is necessary to investigate dwell phenomenon and ballistic performance of the material in the process of projectile penetration. In this paper

the behavior law of dwell is studied by utilizing numerical simulation method. The dwell behavior of aforementioned materials is investigated. Stress level and damage evolution of ceramic composites during dwell process are analyzed

and compared to common armor ceramics at the same condition. It is concluded that energy dissipated during dwell process reaches 845J in ceramic composite

respectively increasing by 46.0%

30.2% and 35.7% to the energy of B4C

SiC and AD99 Al2O3. The damage evolution in ceramic during dwell process is different from that in ceramic and full damaged composites can bear higher compression load than ceramics in the same state. As a result

the damage energy dissipation of composites accounts for 23.9% of the total dwell energy dissipation

which is almost twice as much as that dissipated in ceramic.
