Abstract

A novel 3D printing method for continuous carbon fiber-reinforced thermosetting epoxy resin composites (CCFRTC) was proposed, including CCFRTC prepreg filament manufacturing, secondary impregnation, printing and curing stages. Through the addition of an impregnation stage before printing, this method ensures a close interface bond and uniform distribution of fibers and resin. After testing, the average tensile strength and tensile modulus of the uncured pre-impregnated continuous filaments were found to be 968 MPa and 58.6 GPa, respectively. Mechanical testing of the specimens revealed that the maximum tensile strength and flexural strength of the CCFRTC specimens reached 825 MPa and 557 MPa, with tensile and flexural modulus measuring 157 GPa and 185 GPa. Furthermore, scanning electron microscopy (SEM) examination of the cross-sections indicated a highly uniform impregnation of both the filaments and printed specimens. In conclusion, the method proposed in this study enables the preparation and printing of continuous fiber-reinforced thermosetting resin composite materials, addressing the issues of inadequate impregnation and poor interfacial bonding performance in continuous carbon fiber-reinforced thermosetting resin composite materials. These findings may broaden the potential applications of 3D printing CCFRTC in the aerospace, defense, and automotive industries.

连续碳纤维增强热固性环氧树脂复合材料 3D 打印方法研究

摘要提出了一种新型连续碳纤维增强热固性环氧树脂复合材料（CCFRTC）三维打印方法，包括 CCFRTC 预浸长丝制造、二次浸渍、打印和固化阶段。通过在印刷前增加浸渍阶段，该方法确保了界面的紧密结合以及纤维和树脂的均匀分布。经过测试，未固化的预浸渍连续长丝的平均拉伸强度和拉伸模量分别为 968 兆帕和 58.6 千兆帕。试样的机械测试表明，CCFRTC 试样的最大拉伸强度和弯曲强度分别达到 825 兆帕和 557 兆帕，拉伸模量和弯曲模量分别为 157 GPa 和 185 GPa。此外，横截面的扫描电子显微镜（SEM）检查表明，长丝和印刷试样的浸渍非常均匀。总之，本研究提出的方法实现了连续纤维增强热固性树脂复合材料的制备和印刷，解决了连续碳纤维增强热固性树脂复合材料浸渍不足和界面粘接性能差的问题。这些发现可拓宽三维打印 CCFRTC 在航空航天、国防和汽车行业的潜在应用领域。图表摘要

期刊介绍： Applied Composite Materials is an international journal dedicated to the publication of original full-length papers, review articles and short communications of the highest quality that advance the development and application of engineering composite materials. Its articles identify problems that limit the performance and reliability of the composite material and composite part; and propose solutions that lead to innovation in design and the successful exploitation and commercialization of composite materials across the widest spectrum of engineering uses. The main focus is on the quantitative descriptions of material systems and processing routes. Coverage includes management of time-dependent changes in microscopic and macroscopic structure and its exploitation from the material''s conception through to its eventual obsolescence.
