NASA战略规划确定提供安全和可能的空间通道、轨道转移和星际运输能力的长期目标 ,以使科学研究、人类和机器人探索空间及空间的商业开展成为可能。达到此目标所需技术要求大量的科学和工程上的突破。关键技术包括先进飞行器的主要和次要结构、防辐射、推进和动力系统、燃料贮箱、电子仪器和装置、传感器和科学仪器以及健康诊断和医疗。具有革新性能的先进材料是每种技术的基本要素。对应用于航空航天飞行器结构和推进系统的新型材料进行评述有利于该长期任务规划。全面评价鉴定已经在研的在 5～ 10年内可用的材料 ,以及仍处于初期研究阶段、再过 2 0～ 30年可能不用的那些材料 ;该述评也包括几个系统分析研究的结果 ,着重强调一种改革的新材料 (碳纳米管 )的巨大潜力
The NASA Strategic Plan identifies long-term goals of providing safe and possible space access, orbital diversion and interstellar transport capabilities to make it possible for scientific research, humans and robots to explore commercial spaces and spaces. The technical requirements for achieving this goal require substantial scientific and engineering breakthroughs. Key technologies include the primary and secondary structures of advanced aircraft, radiation protection, propulsion and power systems, fuel tanks, electronic instrumentation and devices, sensors and scientific instrumentation, and health diagnostics and medical. Advanced materials with innovative properties are a fundamental element of every technology. Commenting on new materials for aerospace vehicle structures and propulsion systems is in the interest of this long-term mission. A comprehensive review identifies materials that are already in development within 5-10 years, as well as those materials that are still in the early stages of research and may not be available for another 20-30 years; the review also includes the results of several systematic analysis studies that emphasize A great potential for reforming new materials (carbon nanotubes)
