摘要

以异氰酸酯硬段和聚醚多元醇长链软段为预聚体,合成了模拟肌肉靶的聚氨酯弹性体材料。该聚合物模拟肌靶可常温保存使用。采用9mm手枪子弹作为杀伤元件,在明胶和肌肉模拟材料靶上进行了侵彻实验。通过实验数据对比分析:手枪子弹击穿具有软防护的明胶和聚合物模拟肌肉靶时,其凹陷变化过程基本相同,最大凹陷深度相差9.64%。无保护侵彻实验中,9mm手枪子弹穿透明胶产生的侵彻深度和空腔直径与聚合物模拟肌肉靶一致,最大空腔直径相差12.9%。这种新型高分子材料肌肉模拟标记物在今后的研究中具有较好的应用价值。

COMPARATIVE EXPERIMENTAL STUDY ON THE CHARACTERISTICS OF PISTOL BULLET PENETRATING GELATIN AND POLYMER SIMULATED MUSCLE TARGET
Polyurethane elastomer material-simulated muscle target-was synthesized by prepolymer with isocyanate hard segment and polyether polyol with long chain soft segment. The polymer simulated muscle target could be stored and used at normal room temperature. Penetration experiments were carried out on gelatin and muscle simulated material target, used 9mm pistol bullet as killing element. Through the comparative analysis of experimental data: when the pistol bullet penetrates the gelatin and polymer simulated muscle target with soft protection, the change process of the depression was basically the same, the difference of the maximum depression depth was 9.64%. In the unprotected penetration experiment, the penetration depth and cavity diameter produced by 9mm pistol bullet penetrating gelatin were consistent with those of polymer simulated muscle target, the difference of the maximum cavity diameter was 12.9%. This new polymer material— muscle simulation marker had better application value in future research.
