摘要

摘要: 结合穿甲实验，基于复合材料细观有限元模拟，系统开展针对钨纤维增强金属玻璃复合材料分段弹体侵彻性能的研究，并与复合材料长杆弹进行对比分析。结果表明，相对于复合材料长杆弹显著的穿甲“自锐”行为和优异的侵彻性能，复合材料分段弹体在侵彻过程中的“自锐”特性有所减弱，且弹体结构容易发生分散，进而导致弹体侵彻能力明显降低。另外，分段数目和分段间隔等因素对复合材料分段弹体的侵彻性能具有一定影响，但总体而言，不同构型分段弹体的侵彻能力均弱于复合材料长杆弹。

Abstract: Integrated with the relevant penetrating tests, the ballistic behavior of the tungsten fiber/metallic glass matrix (WF/MG) composite segmented rod is systematically investigated based on the meso-scale finite element method (FEM), and the comparative analysis on the penetrating performance is conducted between the composite segmented rod and the composite long rod. Related analysis shows that the composite long rod has the remarkable “self-sharpening” behavior as well as good penetrating performance, the “self-sharpening” in the composite segmented rod is less significant, and particularly, dispersal of the reinforced fibers is easily to occur in the structure. Correspondingly, the penetrating capability in the composite segmented rod is remarkably weakened compared with that in the long rod. In addition, the segmental number and the segmental interval have considerable effects on the ballistic behavior; however, the penetrating performance of the composite segmented rods with various structures is always lower than that of the composite long rod.
