超高分子量聚乙烯纤维增强塑料（UFRP）层合板具有良好的抗侵彻性能，但受温度影响明显，其热损伤的临界温度仅为147℃。为了避免火灾产生的高温使UFRP层合板失去抗弹性能，设计了以船用钢为前/后面板，SiO2气凝胶毡为隔热层，UFRP层合板为抗弹层的复合抗弹结构。在A60耐火等级标准条件下，对复合抗弹结构的有限元模型进行瞬态热分析，探索了复合抗弹结构内部的温度分布与SiO2气凝胶毡隔温层厚度的关系。根据有限元仿真结果，近一步对SiO2气凝胶毡隔热层厚度为20 mm的复合抗弹结构单元开展耐火试验。结果表明：SiO2气凝胶毡具有良好的隔热性能，在A60耐火等级标准条件下，保持复合抗弹结构中UFRP层合板抗弹性能完好所需的SiO2气凝胶毡隔热层厚度至少为20 mm。
Ultra-high molecular weight polyethylene fiber reinforced plastic (UFRP) laminates has good penetration-resistance, however, the penetration-resistance of UFRP laminates is sensitive to temperature and the critical temperature is 147℃. A sandwich armor structure was designed to protect the antiknock performance of UFRP laminates under the impact of conflagration, and steel is front/rear panel, Silicate Aero-gel is thermal barrier, UFRP laminates is armor for the structure. In order to explore the relationship between temperature distribution of composite armor structure and thickness of silicate aero-gel, a transient thermal analysis on the finite element model of composite armor structure was carried out under the condition of A60 standard. According to the results of finite element simulation, a fire resistance test for composite armor structure also carried out, and the thickness of heat insulation layer is 20 mm. Finally,the results show that silicate aero-gel has good heat insulation performance, and in order to maintain the antiknock performance of UFRP laminates under the condition of A60 standard, the thickness of heat insulation layer in sandwich armor structure should set at least 20 mm.
