连续纤维增强复合材料的3D打印工艺及应用进展

Continuous fiber reinforced composites are widely used in aerospace, automobile manufacturing, smart materials and other fields due to their excellent mechanical properties, flexible design, corrosion resistance, fatigue resistance and a series of advantages. The traditional continuous fiber reinforced composite manufacturing process limits its application in complex structures due to high production costs and process complexity, and the increasing maturity of 3D printing technology provides the possibility to manufacture lightweight and complex continuous fiber reinforced structures. This paper first introduces the printing raw materials and printing methods of continuous fiber reinforced composites, summarizes the influence of different processes on the printing process and results, then analyzes its application prospects in different fields, and finally discusses the current research problems and looks forward to the future development of continuous fiber reinforced composites 3D printing.
