碳-碳复合材料,已是当前公认最好的再入防热材料。碳-碳材料的工程应用,也已日趋成熟,已成功地用于美国民兵Ⅲ洲际导弹弹头。现在人们普遍关心的是:在存在粒子侵蚀的再入环境下,碳-碳材料是否仍能胜任?从改进碳-碳工艺结构着手,提高碳-碳材料的抗侵蚀性能到底有多大潜力? Carbon-carbon composite materials, is now recognized as the best re-entry heat-resistant materials. The engineering application of carbon-carbon materials has also matured and has been successfully used in the U.S. militia III intercontinental missile warheads. At present, people are generally concerned about whether carbon-carbon materials can still be qualified in the presence of particle erosion. How much potential is there to improve the anti-erosion performance of carbon-carbon materials by improving the carbon-carbon process structure?
