| Abstract: |
| Fiber-reinforced polymer composites have been widely used in spacecraft. Whereas, on-orbit manufacturing (OOM) technology has become a crucial development direction for aerospace composites. This paper first analyzes the current status of OOM technology and then requirements for on-orbit manufacturing of composite components as well as structures are concluded. Based on these requirements, the potential applicability of frontal-polymerized composite materials in on-orbit manufacturing is discussed. Furthermore, a promising process based on frontal polymerization-direct ink writing (FP-DIW) technology is proposed for future on-orbit manufacturing. The proposed technology has many advantages, such as energy-saving, fast curing, and being able for in situ, as well as un-supported manufacturing. These features make it very suitable for on-orbit manufacturing. In conclusion, the discussions in this paper shed light on novel materials and manufacturing processes for fabricating composite components in space. |
