3D打印技术在航天复合材料制造中的应用

The Application of 3D Printing Technology in Space Composites Manufacturing

复合材料作为新一代结构材料已大量应用在航天遥感器结构中,如相机支架、承力框、遮光罩等。低成本、高效率的制造技术是进一步推进复合材料应用的重要途径,三维(Three dimension,3D)打印技术的出现为复合材料的低成本快速制造提供了可能,随着技术的发展,复合材料的3D打印技术逐渐成为该技术的一个新兴领域。文章介绍了以纤维增强树脂基复合材料为打印材料的3D打印技术的研究情况,结合航天遥感器用复合材料产品的特点对3D打印技术在航天复合材料产品制造上的应用进行了分析。

AbstractAdvanced composites have been used as new general structural materials, in structures of space remote sensors such as camera brackets, load-carrying frames, and baffles. Manufacturing technologies with low cost and high efficiency could promote the application of advanced composites further. A 3D printing technology can make the composites manufacture lower cost and higher efficiency. With the development of the technology, 3D printing of composites is becoming a new field. This paper introduces the development of 3D printing technology using fiber reinforced resin composites in China and abroad, and then analyzes the application of 3D printing technology in space with the characteristics of composite products used in space remote sensors.
