In additive manufacturing of continuous fiber reinforced ceramic composites, the carbon fiber is difficult to give full play to its toughening effect without interface, and the high-viscosity resin, ceramic precursors or slurry is hardly to fully infiltrate into fiber bundles, which are not conducive to obtain high-performance ceramic composites. In this work, sugar-derived carbon acts as interface was deposited on continuous carbon fiber by hydrothermal reaction. Flexible hydrothermal carbon-coated continuous carbon fiber is appropriate for 3D printing. Continuous carbon fiber/ZrB 2 -polycaprolactone(PCL) filaments used for fused deposition modeling (FDM) was prepared by pre-impregnation-coating process. Ultrasound significantly improves the impregnation effect of ceramic slurry into fiber bundles. C f /ZrB 2 -PCL billets with different fiber orientations were fabricated by FDM of continuous C f /ZrB 2 -PCL filaments. The C f /ZrB 2 -PCL billets were further densified by infiltration and pyrolysis of SiC precursor. The flexural strength and fracture toughness of C f /ZrB 2 -SiC composites could reach 218.1 ± 21.3 MPa and 9.40 ± 1.45 MPa m1/2, respectively. [ABSTRACT FROM AUTHOR] |
