| 摘 要： | 以烧蚀发动机为主要试验手段,结合全自动密度仪、扫描电镜、微米CT等多种测试手段,对不同烧蚀环境下EP-DM绝热材料炭化层的结构特征及其对烧蚀的影响规律进行了深入研究.研究发现,炭化层呈多孔疏松结构,其孔隙大部分为开孔;EPDM绝热材料的炭化层存在致密/疏松结构,而这种结构与烧蚀环境有很大关系;在炭化层表面形成一定厚度的...

| Abstract: | The investigation of carbonized layer structural features and its influence on ablation characteristic of EPDM insulator was carried out under different ablation modes through the ablation test motor,densimeter,scanning electron microscope and micron CT.The results show that the carbonized layer was a typical porous and loose material and a majority of the aperture was opened;Compact/loose structures were formed in carbonized layer of EPDM insulator,which was related with ablation conditions;The erosion res... |
