Investigation on process parameters of 3D printed continuous carbon fiber-reinforced thermosetting epoxy composites

Continuous fiber-reinforced thermosetting polymer composites (CFRTPCs) were prepared via three-dimensional (3D) printing in this study. The entire process was divided into impregnation, printing, and curing stages. The impregnation stage ensured a tightly bonded interface and uniform distribution of fibers and resin. The printing stage solved the great conveying resistance and poor adhesion caused by the addition of continuous fibers. The curing...
