SIO2气凝胶毡/陶瓷棉/高强聚乙烯多层复合抗弹结构隔热性能试验
Experiment on the thermal insulation performance of multi-layer composite ballistic structures by silicate aero-gel/ceramic/high-strength polyethylene
摘要
Abstract
In order to research the reliability of high strength polyethylene under high temperature condi⁃tions and the heat insulation properties of SiO2 aero-gel and ceramic cotton, the SiO2 aero-gel blanket/ce⁃ramic cotton with high strength polyethylene integrated structure scheme with no clearance was put for⁃ward. The standard fire test was performed on the structural unit. The failure mode of the refractory material and the influence law of refractory thickness on the sandwich structure were analyzed. The study discusses the practicality of area density and the overall thickness of the structure on the premise that the composite structure bulkheads satisfies the refractory requirements. The results show that the advisable thickness of the SiO2 aero-gel blanket and ceramic cotton each have good refractory insulating performance, and the thermal protection effect of the composite bulkhead structure is obviously improved with the higher thick⁃ness of the insulating layer. To achieve the same effect, less SiO2 aero-gel blanket is needed than ceramic cotton;the SiO2 aero-gel blanket is superior when considering area density and whole structure thickness;and the ceramic also has a certain insulating effect when added to the sandwich structure. As such, the inte⁃grated optimization of the composite bulkhead structure can effectively improve the protective performance of marine bulkheads.关键词
