摘要

摘要: 基于均质钢板、聚脲涂层材料、SiC陶瓷材料设计了4种聚脲涂覆复合装甲结构，采用装药驱动预制破片试验方法开展了近炸下复合装甲结构毁伤特性实验研究，提出了各组分的毁伤破坏模式，对比分析了4种防护装甲结构的防护性能，探讨了复合装甲结构的防护机理。结果表明：作用于目标结构的破片动能远大于冲击波能，聚脲涂覆复合装甲结构的防护效能明显优于多层均质钢装甲，增加陶瓷厚度较增加背板、前面板厚度对提高整体防护效能更有效，破片撞击将引起陶瓷块大面积损伤，严重影响了其对后续着靶破片的防护性能。

Abstract: Four types of polyurea coated composite armor structures were designed based on steel plates, SiC ceramic tiles and polyurea coatings. The near-field explosion damage characteristics of the composite armor structures were experimentally studied using the method of charge driven prefabricated fragments. The failure modes of the components of the armor structures were proposed, the protection performances of the armor structures were comparatively analyzed and the protection mechanisms were investigated. The experimental results indicate that the impact energy acted on the structures by the prefabricated fragments is far greater than that of the blast wave. The protection performances of the polyurea coated composite armor structures are much better than those of the multi-layer steel structures. Increasing the thickness of ceramic tiles can enhance the protection performance more efficiently than increasing the thickness of the front plate or back plate. Under the impact of fragment cluster, ceramic tiles are damaged on a large scale, and the anti-penetration capability against subsequent hitting fragments will be severely weakened.
