3D打印连续碳纤维增强热塑性聚合物研究进展OA
Research progress on 3D printed continuous carbon fiber reinforced thermoplastic polymers
熔融沉积成型(fused filament fabrication,FFF)技术具备设计灵活度高、无需模具且能快速构建复杂结构的显著优势,是连续碳纤维增强热塑性聚合物(continuous carbon fiber reinforced thermoplastic polymer,CCFRTP)3D打印的关键方法.但在实际3D打印过程中,由于FFF工艺本身的限制,如打印温度、层间结合、纤维浸润不充分等,常导致CCFRTP构件出现界面结合弱、孔隙率高等问题,严重影响其力学性能.为此,本文围绕3D打印工艺特点,重点评述了近年来在树脂改性、纤维改性及其协同优化等方面的最新研究进展,特别是多种协同改性策略在提升界面性能方面的作用机制.在此基础上,探讨FFF最新研究进展及不同打印工艺参数对力学性能的影响及优化方式,并对其发展方向与应用前景进行了展望.
Fused filament fabrication(FFF)technology boasts significant advantages,including high design flexibility,mold-free operation,and the capacity to rapidly construct complex structures,making it a key method for 3D printing of continuous carbon fiber reinforced thermoplastic polymer(CCFRTP).However,during the actual printing,CCFRTP often experiences a decline in mechanical properties due to insufficient interfacial bonding between the thermoplastic matrix and the continuous carbon fiber reinforcement,as well as a high internal porosity.To address this issue,this paper analyzes two major factors influencing the performance—the resin matrix and the carbon fiber reinforcement.Based on this,it reviews the recent advances in FFF technology,examines the effects of various printing parameters on mechanical properties,along with optimization strategies.Finally,future development directions and application prospects are discussed.
