摘　　要：采用M80弹(7.62 mm×51 mm NATO)分别对常温和高温(55℃)下的防弹插板进行实弹射击试验,以研究高温环境对防弹插板抗弹性能的影响。通过分析试验时防弹插板弹击瞬间凹陷值,同时结合聚氨酯树脂的剥离强度、超高分子量聚乙烯纤维层压板剥离强度和弯曲强度的测试结果对高温下抗弹性能变化原因进行了研究。结果表明:高温下防弹插板抗弹性能明显下降,相对于常温下每发弹的弹击瞬间凹陷值增加了2~5 mm。其主要原因是超高分子量聚乙烯纤维层压板在高温下抵抗变形的能力发生明显下降,从而导致防弹插板的弹击瞬间凹陷值增大。In order to study the influence of high temperature environment on the ballistic performance of the ballistic insert plate,M80(7.62 mm×51 mm NATO)was used to carry out live firing tests on bullet-proof inserts at room temperature and high temperature(55℃)respectively.The reasons for the change of ballistic performance at high temperature were studied by analyzing the instant dent value of bullet hit during the test and combining with the test results of stripping strength of polyurethane resin,stripping strength and bending strength of UHMWPE fiber laminates.The results show that the ballistic performance of the ballistic insert plate decreases significantly at high temperature.The instant dent value of bullet hit of each bullet increases by 2~5 mm compared with that at room temperature.The main reason is that the deformation resistance of UHMWPE fiber laminate under high temperature decreases significantly,which leads to the increase of the instant dent value of bullet hit.
