未来用于载人登月、深空探测的重型运载火箭直径约为我国现役运载火箭的2～3倍,为满足超大型树脂基复合材料结构的高刚度、轻量化、高可靠的要求,未来材料性能和大尺寸构件成型工艺水平必须较现有体系有明显提高。中国航天科技集团公司国防基础科研重大项目——“结构复合材料关键材料体系的工程化应用技术研究”已成功立项,研究成果将满足未来航天型号发展需求。该项目由
In the future, the diameter of heavy-duty launch vehicle used for manned lunar and deep space exploration is about 2 to 3 times that of the existing active rocket in the country. In order to meet the requirements of high rigidity, light weight and high reliability of the ultra-large resin-based composite structure, Material properties and large-size component molding process level must be significantly higher than the existing system. China Aerospace Science and Technology Corporation, a major national defense science and research major projects - “structural materials of the key composite materials engineering application technology research ” has been successfully approved, the research results will meet the future development needs of aerospace models. The project consists of
