| 材料是影响太空制造工艺以及装备的重要因素之一，实现空间材料的原位回收与再利用对于降低地面供给、提高航天便捷性以及运行经济性等方面具有重要意义，特别是对于空间站的运营以及地外天体原位资源利用。本文从太空制造面临的环境因素与轨道工厂产品的应用场景出发，总结了太空制造的材料体系，对原位可用的材料从可回收材料体系与原位资源利用两个角度分析了航天材料的地面回收和再利用方案，重点分析与总结了玻璃与陶瓷、聚合物、金属和合金及电子废弃物的回收与再利用流程，并针对传统的“制造-使用-废弃”太空探索的范式，提出了太空制造的材料回收与再利用的总体新思路，倡议从初始的材料、设计太空物体与零部件、建立供应链、制造与装配技术、使用与维护技术、寿命终止评价到材料回收与再利用的全局建立闭环的自我维持的太空制造生态系统。 |

| Abstract: |
| Materials are one of the important factors affecting space manufacturing processes and equipment. The in-situ recovery and reuse of space materials are significant for reducing ground supply, improving aerospace convenience, and improving the operational economy, especially for operating space stations and utilizing the in-situ resources of extraterrestrial celestial bodies. This article starts from the environmental factors faced by space manufacturing and the application scenarios of orbit factory products, summarizes the material system of space manufacturing, and analyzes the ground recycling and reuse schemes of aerospace materials from the perspectives of recyclable material systems and in-situ resource utilization for materials available in-situ. The focus is on analyzing and summarizing the recycling and reuse processes of glass and ceramics, polymers, metals and alloys, and electronic waste. A new overall approach for material recycling and reusing in space manufacturing has been proposed in response to the traditional paradigm of “manufacturing-use-disuse” space exploration. A proposal was put forward to establish a self-sustaining space manufacturing ecosystem that encompasses the entire process, from initial materials to the design of space objects and components, establishment of a supply chain, manufacturing and assembly technology, usage and maintenance technology, end-of-life assessment, to material recycling and reuse. |
