Abstract A comprehensive experimental and numerical simulated pool fire test is conducted on stainless steel composite metal foam (S–S CMF) panels and is reported in this study. The uncertainty assessments for the measured and calculated unexposed surface temperatures in the calibration and simulated pool fire tests on the S–S CMF specimens are also conducted and reported. This test procedure is designed to measure the thermal performance of new or untried thermal protection systems, such as S–S CMF, and to test for its survivability when exposed to a 100-min pool fire condition. The assembly was tested in triplicate in three consecutive simulated pool-fire exposures as specified in 49 CFR Part 179, Appendix B and achieved successful results. Based on the experimental and modeling results as well as the uncertainty studies, the 15.9 mm thick steel-steel composite metal foams tested as a novel insulation system met the acceptance criteria for the simulated pool fire test specified in 49 CFR 179 Appendix B by a large margin and is expected to pass with near certainty if the test were to be reproduced in a different laboratory. The main reason for successful performance of S–S CMF is attributed to the large air content in the material. The numerical studies reported in this study indicated that the low surface emissivity of the material is also contributing to the superior performance of the material to some extent. To complete the full test requirements of CFR Part 179 App. B, the material will need to be tested against the torch-fire exposure in duplicate. This research indicates that one of the potential applications of lightweight S–S CMF can be in tank cars carrying hazardous materials and replacing conventional structural steel with demonstrated benefits of excellent thermal insulation, fire resistance, low weight along with its established energy absorption capabilities.

钢-钢复合泡沫金属模拟水池火灾试验

摘要 本研究报告了对不锈钢复合泡沫金属 (S-S CMF) 面板进行的综合实验和数值模拟池火灾试验。还对 S-S CMF 样本的校准和模拟池火灾测试中测量和计算的未暴露表面温度的不确定性评估进行了评估。该测试程序旨在测量新的或未经测试的热保护系统（例如 S-S CMF）的热性能，并测试其在暴露于 100 分钟的水池火灾条件下的生存能力。按照 49 CFR 第 179 部分附录 B 中的规定，在三个连续的模拟池火暴露中对组件进行了三次重复测试，并取得了成功的结果。根据实验和建模结果以及不确定性研究，15. 9 毫米厚的钢-钢复合泡沫金属作为一种新型绝缘系统进行测试，大大满足了 49 CFR 179 附录 B 中规定的模拟水池火灾测试的验收标准，并且如果要进行测试，预计几乎可以肯定地通过在不同的实验室复制。S-S CMF 性能成功的主要原因是材料中的大量空气含量。本研究报告的数值研究表明，材料的低表面发射率也在一定程度上有助于材料的优越性能。完成 CFR Part 179 App 的完整测试要求。B，材料将需要针对火炬-火焰暴露进行一式两份测试。
