Research progress in 3D printing of continuous fiber-reinforced resin matrix composites
连续纤维增强树脂基复合材料因其密度低、力学性能优异被广泛应用于航空航天、汽车和船舶等工业领域,传统制造工艺因模具限制成本高昂且无法成型复杂零部件。增材制造设计自由度高、快速灵活等优点被认为是连续纤维增强复合材料未来生产的重要方向之一。目前连续纤维增强复合材料的增材制造技术发展仍处于起步阶段,本文系统综述了连续纤维增强树脂基复合材料的研究现状,概述了打印的装备、工艺、材料的研究进展,为连续纤维增强树脂基复合材料的打印平台搭建以及工程化应用提供了方向,重点分析了打印温度、打印速度和打印层厚等工艺参数对打印质量的影响,为连续纤维增强复合材料的智能增材制造提供参考,同时讨论了连续纤维的二维和三维的结构设计在轻量化制造方面的发展,如纤维路径铺设和结构拓扑优化,并对连续纤维增强复合材料增材制造的设备、材料、打印工艺和结构设计的研究发展趋势进行了总结和展望。
Continuous fiber-reinforced resin matrix composites are widely used in aerospace, automotive and marine industries due to their low density and excellent mechanical properties. However, traditional manufacturing processes are expensive and unable to form complex parts due to mold limitations. Additive manufacturing has the advantages of high freedom of design, rapidity, and flexibility,and is considered an important directions for the future production of continuous fiber reinforced composites. At present, the additive manufacturing technology of continuous fiber reinforced composite is still in its infancy. This paper systematically reviews the research status of continuous fiber reinforced resin matrix composite, summarizes the research progress of printing equipment, process and materials, and provides directions for the construction of printing platform and engineering application of continuous fiber reinforced resin matrix composite. The influence of printing process parameters, such as temperature, speed, and layer thickness on printing quality is analyzed, providing a reference for the intelligent additive manufacturing of continuous fiber reinforced composite materials. Meanwhile, the development of the two-dimensional and three-dimensional structural design for continuous fibers for lightweight manufacturing, such as fiber path laying and structural topology optimization is discussed. The research trends of equipment, materials, printing process, and structural design for additive manufacturing of continuous fiber-reinforced composites are summarized and outlooked.
