3D Printing for High Performance Fiber Reinforced Polymer Composites and Exploration on Its Applications

纤维增强树脂基复合材料具有优异的力学性能,能够实现轻质、高性能结构的制造,但传统的成型工艺过程复杂、成本高,难以实现纤维回收利用,限制了纤维增强树脂基复合材料的广泛应用。3D打印技术是一种新兴的零件成形工艺,将3D打印技术应用于纤维增强树脂基复合材料的制造,为实现复合材料低成本、绿色制造提供了可能性。综述了纤维增强树脂基复合材料3D打印技术研究的发展现状,提出了一种高性能连续纤维增强热塑性复合材料3D打印工艺及其回收再制造策略。

Fiber reinforced polymer composites can lead to significant weight loss and great improvement of combination properties because of their inherent advantages. However, the disadvantages of conventional forming processes, such as complex process, high cost, difficult recycling, have limited the wide applications of fiber reinforced polymer composites. 3D printing is a new forming process of parts, and it is possible to realize low-cost and green manufacturing for fiber reinforced polymer composites. This paper reviews the research status of 3D printed fiber reinforced polymer composites, and meanwhile presents a new 3D printing process for high performance continuous fiber reinforced thermoplastic composites as well as the recycling and remanufacturing strategy for the parts fabricated by this new process.
