Investigation of a 3D Printing Method for Continuous Carbon Fiber-Reinforced Thermosetting Epoxy Composite
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.
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.
