摘要
本论文为减小背衬胶泥的凹陷深度,减轻子弹冲击对人体造成的非贯穿性损伤,设计一种两侧均附有面密度为150 g/m^2的超高分子量聚乙烯纤维增强树脂基复合材料的EVA泡沫作为新型抗凹陷结构材料层。采用弹道测试系统进行打靶测试,研究新型抗凹陷结构材料层对防护性能的影响,并计算出靶片影响系数Φ。结果表明添加新型抗凹陷结构材料的靶片防护性能较好,新型抗凹陷结构材料的使用既能够防止子弹冲击时造成的吸波层的损坏,明显降低防弹材料受到子弹冲击后的凹陷深度,减小非贯穿性损伤,又能够进一步提高防弹材料的防弹能力。
In this paper, the new anti-trauma material was prepared by EVA foam which was sticked ultra-high molecular weight polyethylene fiber reinforced resin matrix composites of areal density of 150 g/m^2 on both sides. The influence of new anti-trauma material on ballistic performance was investigated by ballistic testing, and the influence coefficient Φ was calculated. It was shown that the adding of the new anti-trauma material improve protection performance.
