Investigation on Fabrication of Continuous Carbon Fiber-ReinforcedThermosetting Furan Resin Composite Using ۳D-Printing

Continuous carbon-fiber-reinforced furan resin was manufactured using fused deposition modeling(FDM). Carbon fibers were impregnated with furan resin-ParaToluene sulfonic acid (PTSA) before۳D printing. Thermoset composites outperform thermoplastics due to higher modulus, low-viscosityresin, better fiber impregnation, and proper fiber adhesion. In this study, continuous fiber-reinforcedthermoset composites (CFTCs) have been fabricated using ۳D printing, varying nozzle diameters(۰.۹, ۱.۳, ۱.۶ mm), five different fibers content (۱۳-۲۱ pieces), and print speed (۳۰, ۹۰, and ۱۵۰mm/min). Composite quality was assessed by void content and visual evaluation to establish optimalprint conditions. Printed samples with a ۱.۶mm nozzle and ۱۷ fiber content showed the best results,with void content less than ۲۳% at various print speeds.
