3D打印连续纤维增强树脂基复合材料的研究进展

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.
