中文摘要:
      目的 为了研究自然老化防弹衣对人体的防护能力,开展手枪弹对有防护明胶靶标的钝击效应试验。方法 通过高速摄影拍摄钝击过程中明胶靶标内瞬时凹陷情况,以此判断自然老化是否影响防弹衣的防护性能。结果 试验结果表明,10年自然老化防弹衣防护下的明胶靶标内平均瞬态最大凹陷深度为23.32 mm,平均最大直径为70.08 mm;新软质防弹衣防护下的明胶靶标内平均最大凹陷深度为28.76 mm,平均最大直径为66.59 mm。结论 10年自然老化对软质防弹衣的抗弹性能没有显著影响。文中的研究给自然老化软质防弹衣安全使用寿命的延长提供了参考。
英文摘要:
      In order to study the protective performance of naturally aged bulletproof vests on human body, the work aims to conduct the impact experiment to examine the blunt impact effect of handgun bullets on gelatin targets with protective measures. The instantaneous concavity in the gelatin target during blunt impact was photographed by high-speed photography to determine whether natural aging affected the protective performance of bulletproof vests. The experimental results showed that, under the protection of bulletproof vests aged over 10 years, the average instantaneous maximum concave depth in the gelatin targets was 23.32 mm and the average maximum diameter was 70.08 mm. In comparison, for gelatin targets protected by new soft bulletproof vests, the average maximum concave depth was 28.76 mm and the average maximum diameter was 66.59 mm. The natural aging for 10 years does not significantly affect the bullet-resistant performance of the soft bulletproof vests. This study provides reference information for extending the safe service life of naturally aged soft bulletproof vests.
