  • 摘要: 近年来,连续纤维增强聚合物复合材料的相关研究已成为材料领域的关注热点,相比于金属、陶瓷等结构材料,其具有更高的设计性、比强度、断裂韧性、疲劳寿命和耐腐蚀特性,在航空航天、轨道交通、风电能源、机械工业等领域具有广阔的应用前景。连续纤维增强聚合物复合材料与增材制造技术的有机结合对于高端装备的轻量化、结构功能一体化制造具有重要意义。本文针对连续纤维复材增材制造过程中的挤出与浸渍方式、打印温度、辅助工艺、打印速度、打印间距、几何构建方式等工艺研究的国内外最新进展情况进行了全面的综述,着重论述了各工艺参数对成形件性能的影响,并对目前面临的挑战和未来发展进行展望。

     

    Abstract: Compared with metal, ceramic or other structural materials, continuous fiber-reinforced polymer composites can offer significant advantage for their excellent design tailorability, mechanical properties, fracture toughness, good resistance to corrosion and fatigue, and are widely used in aerospace, transportation, energy, machinery and other fields. The organic combination of continuous fiber-reinforced polymer composites and additive manufacturing technology has the potential to promote new revolution for weight saving and structure-function integrated manufacturing of high-end equipment. This paper reviewed the recent research progress of extrusion and impregnation methods, printing temperature, auxiliary process, printing speed, printing spacing and geometric construction methods in additive manufacturing of continuous fiber composites. The influence of various process parameters on properties of the formed parts was emphatically discussed. Finally, the present challenges and future development directions have been prospected for reference.
