| 摘 要： | 成功制备了一种新型多层隔热材料, 其间隔层基于氧化铝纤维制备, 并由溶胶-凝胶法植入二氧化硅气凝胶颗粒。在高真空环境下(10-3 Pa), 新型多层隔热材料当量热导率比传统材料低21.8%, 同时重量比传统材料降低了67.2%。此外, 这种新型多层隔热材料在1200 K的高温以及低真空条件下(100 Pa)也表现出良好的隔热性能。

| Abstract: | A new kind of MLIMs are prepared, whose spacer is made from Al2O3 fiber mat, and silica aerogels is implanted on the surface of Al2O3?fiber through Sol-Gel process. In high vacuum (10-3 Pa), the effective thermal conductivity of the new MILMs could be reduced by 21.8%, at the same time, the weight could be reduced by 67.2%. Furthermore, this MLIMs shows good insulation performance in high temperature of 1200 K and low vacuum (100 Pa). |
