本文采用平板叶片弹丸对多层Kevlar 49机织织物进行了弹道冲击试验，研究了风扇叶片脱落时的冲击响应。重点讨论了芳纶纤维层数和预张力对复合材料力学性能的影响。利用试验结果分析了多层芳纶织物的失效模式和能量吸收特性。结果表明：织物的冲击损伤主要有两种：一种是以冲击区纱线拉伸和织物从两侧向冲击区起皱为主的整体变形;另一种是以纱线断裂、纱线拔出和纱线散开为主的局部损伤。Kevlar 49机织织物的能量吸收能力随着织物层数的增加而提高。多层织物吸收的能量在开始时略有增加，然后随着预张力的增加而显著降低。本文的工作可为多层轻质织物围护结构的设计提供指导。
In this paper, ballistic impact tests on wrapped multi-layer Kevlar 49 woven fabric systems were carried out with a flat blade projectile to investigate the impact response during a fan blade out event. The influences of the number of Kevlar layers and pre-tension were discussed particularly. Test results were used to analyze failure modes and energy absorption characteristics of multi-ply Kevlar fabrics. Results show that there are two kinds of impact damage for fabrics: global deformation mainly involving stretching of yarns in the impact region and fabric wrinkle from both sides to the impact zone, and local damage characterized by yarn fracture, yarn pull-out, and yarn unraveling. The energy absorption capability of Kevlar 49 woven fabrics improves with the number of fabric layers. The energy absorbed by multi-layer fabrics increases slightly at the beginning and then decreases substantially with pre-tension. The work in this paper can provide guidance for designing light-weight multi-layer fabrics containment systems.
