“…The used nano SiC powder with an average size of 40 nm was purchased from Aladdin Chemical Reagent Co., Ltd. PAN‐based T800HB‐6K carbon fibers were used as a reinforcing material. Continuous carbon fiber reinforced ZrB 2 –SiC composites were fabricated via direct ink writing combined with low‐temperature hot‐pressing based on our previous work 17 . Carbon fibers coated with hydrothermal carbon and a ZrB 2 –SiC ceramic slurry were used to fabricate ZrB 2 –SiC ceramic green bodies via direct ink writing, and then the green bodies were hot‐pressed at 1500°C for 1 h to obtain C f /ZrB 2 –SiC composites.…”

“…The preparation of two-dimensional (2D) carbon-fiber nonwoven fabric toughened UHTC composites via pressure sintering could overcome the aforementioned technical barriers 16 . Although it has been reported that continuous carbon fiber toughened ZrB 2 -SiC composites fabricated via direct ink writing combined with low-temperature hot-pressing exhibit excellent flexural strength and fracture toughness 17 , their oxidation resistance at high or ultrahigh temperatures has not been investigated. The mechanical and oxidation resistance of UHTCs have been investigated deeply in the past 20 years.…”

Although C f /ZrB 2 -SiC composites prepared via direct ink writing combined with low-temperature hot-pressing were shown to exhibit high relative density, high preparation efficiency, and excellent flexural strength and fracture toughness in our previous work, their oxidation and ablation resistance at high and ultrahigh temperatures had not been investigated. In this work, the oxidation and ablation resistance of C f /ZrB 2 -SiC composites were evaluated via static oxidation at high temperature (1500 • C) and oxyacetylene ablation at ultrahigh temperatures (2080 and 2270 • C), respectively. The thickness of the oxide layer of the C f /ZrB 2 -SiC composites is <40 μm after oxidizing at 1500 • C for 1 h. The C f /ZrB 2 -SiC composites exhibit non-ablative properties after oxyacetylene ablation at 2080 and 2270 • C for >600 s, with mass ablation rates of 3.77 × 10 −3 and 5.53 × 10 −3 mg/(cm 2 s), and linear ablation rates of −4.5 × 10 −4 and −5.8 × 10 −4 mm/s, respectively. Upon an increase in the ablation temperature from 2080 to 2270 • C, the thickness of the total oxide layer increases from 360 to 570 μm, and the carbon fibers remain intact in the unaffected region. Moreover, the oxidation and ablation process of C f /ZrB 2 -SiC at various temperatures was analyzed and discussed.

A novel additive manufacturing approach is herein reported for manufacturing high mechanical strength continuous carbon fiber-reinforced silicon carbide (C f /SiC) composite materials. Continuous carbon fibers were coated with polycarbosilane (PCS) using a colloidal evaporative deposition process and then coextruded with high solid content SiC ink. The zeta potential of the SiC ink was adjusted to optimize the printing ability of the suspension. During sintering, small SiC grains and whiskers were generated in the gaps in and around the PCS-coated carbon fibers, which led to the improved flexural strength and density of the composites. Meanwhile, the PCS coating on the surface of the carbon fibers prevented the carbon fibers from reacting with SiO gas generated by reactions between the SiC matrix and SiO 2 and sintering additives (Al 2 O 3 and Y 2 O 3 ), effectively preserving the structural integrity of the carbon fibers. Compared to the SiC specimens containing uncoated carbon fibers, the density of the specimens fabricated with coated carbon fibers was increased from 2.51 to 2.85 g/cm 3 , and the strength was increased from 190 to 232 MPa.

“…28,29 Mei et al 30 obtained continuous carbon fiber (C f )-reinforced SiC composites with a bending strength of 120 MPa by fused deposition modeling (FDM) printing filaments prepared by mixing thermoplastic resin with ceramic precursors and pyrolyzing them in an argon atmosphere. Liu et al 31 prepared C f /ZrB 2 -SiC composites with a bending strength of 388 MPa by MEX combined with ultrasonic dispersion and low-temperature hot-pressing sintering, but their preparation method was also dependent on the mold and thus could not fabricate C f -reinforced composites with complex structures. Few research studies on 3D printing C f -reinforced silicon carbide ceramic composites are available yet, as C f is more difficult to be introduced into SiC ceramics than C sf .…”

A material extrusion (MEX) technology has been developed for the additive manufacturing of continuous carbon fiber–reinforced silicon carbide ceramic (Cf/SiC) composites. By comparing and analyzing the rheological properties of the slurries with different compositions, a slurry with a high solid loading of 48.1 vol% and high viscosity was proposed. Furthermore, several complex structures of Cf/SiC ceramic composites were printed by this MEX additive manufacturing technique. Phenolic resin impregnation–carbonization process reduces the apparent porosity of the green body and protects the Cf. Finally, the reactive melting infiltration (RMI) process was used to prepare samples with different Cf contents from 0 to 2 K (a bundle of carbon fibers consisting of 1000 fibers). Samples with Cf content of 1 K show the highest bending strength (161.6 ± 10.5 MPa) and fracture toughness (3.72 ± 0.11 MPa·m1/2) while the thermal conductivity of the samples with the Cf content of 1 K reached 11.0 W/(m·K). This study provides a strategy to prepare Cf/SiC composites via MEX additive manufacturing and RMI.
