为了开发用于燃气涡轮机发动机、风扇安全壳的新型材料或结构，对混杂复合材料夹层结构的抗弹道冲击性能进行了评价。所研究的夹层结构由GLARE-5（Aviation Equipment，Inc.，Costa梅萨，CA）层压为面板，其具有轻质多孔金属材料如蜂窝、泡沫和格子块作为芯材料。这些混合夹层结构的耐冲击性进行了比较，GLARE-5层压板和2024-T3铝片，这是作为面积重量（材料厚度）的函数进行测试。GLARE-5层压板在低面积重量下表现出与2024-T3 Al相当的冲击性能，即使这些材料的静态拉伸性能存在显著差异。然而，GLARE-5在更高的面积重量下确实具有比直铝板更大的弹道极限。此外，与直2024-T3 Al相比，GLARE-5/泡沫夹层结构在弹道极限方面有高达25%的优势。但在任何混合夹层结构和较厚版本的GLARE-5之间没有观察到弹道极限方面的优势。根据这些初步数据，对今后的工作提出了建议。
The ballistic impact resistance of hybrid composite sandwich structures was evaluated with the ultimate goal of developing new materials or structures for potential gas turbine engine, fan containment applications. The sandwich structures investigated consisted of GLARE-5 (Aviation Equipment, Inc., Costa Mesa, CA) laminates as face sheets with lightweight cellular metallic materials such as honeycomb, foam, and lattice block as a core material. The impact resistance of these hybrid sandwich structures was compared with GLARE-5 laminates and 2024-T3 Al sheets, which were tested as a function of areal weight (material thickness). The GLARE-5 laminates exhibited comparable impact properties to that of 2024-T3 Al at low areal weights, even though there were significant differences in the static tensile properties of these materials. The GLARE-5, however, did have a greater ballistic limit than straight aluminum sheet at higher areal weights. Furthermore, there is up to a 25% advantage in ballistic limit for the GLARE-5/foam sandwich structures compared with straight 2024-T3 Al. But no advantage in ballistic limit was observed between any of the hybrid sandwich structures and thicker versions of GLARE-5. Recommendations for future work are provided, based on these preliminary data.
