摘　　要：为平衡防弹材料自重、灵活性、舒适性与防弹性能之间的关系,以芳纶纤维全幅衬纬针织物为增强体、沙林树脂为基体材料,制备3种不同规格的柔性防弹复合材料。为探究全幅衬纬针织物/沙林树脂复合材料的弹道侵彻性能,对其进行不同速度下的弹道冲击测试,并采用XCT断层扫描探究复合材料内部的损伤扩展情况,分析其损伤机理及失效模式。结果表明:3种全幅衬纬针织物/沙林树脂复合材料的弹道极限速度分别为365.31,339.76和338.29 m/s;且在弹丸冲击作用下,复合材料迎弹面倾向于发生剪切破坏,背弹面倾向于发生拉伸破坏,复合材料具体损伤模式受到弹丸入射速度的影响。研究结果验证了全幅衬纬针织物增强复合材料在防弹领域的应用潜力。To balance the relationship between the weight,flexibility,comfort,and ballistic performance of bulletproof materials,three types of flexible bulletproof composite materials with different specifications were prepared using full-width weft insertion knitted fabric as reinforcement and Surlyn resin as matrix material.In order to investigate the ballistic penetration performance of full-width weft insertion knitted fabric/Surlyn resin composites,high velocity impact tests were conducted at different impact velocities.XCT scanning was used to explore the internal damage image of the composites,the damage mechanism and failure mode were comprehensively studied.The results show that the ballistic limit velocities of full-width weft insertion knitted fabric/Surlyn resin composites are 365.31 m/s,339.76 m/s,and 338.29 m/s,respectively.Moreover,for the composites reinforced by weft insertion fabrics,the front layers tend to be destroyed in shear,while the back layers are more probably to fail in tension.Further,the specific damage modes of the composites are affected by the impact velocities of the projectile.It shows that the full-width weft insertion knitted fabric reinforced composites have tremendous application in the field of bulletproof.
