Here, we report a method for fabrication of robust and near-net shaped carbon-fiber reinforced silicon carbide (Cf/SiC) through the additive manufacturing method of material extrusion. The addition of fibers allows for enhanced damage tolerance and thermal shock resistance but little is known about the resulting affects to resulting ink rheology, printability and resulting fiber alignment in the printed components. As such, three separate inks were developed with carbon fiber loadings of 0 %, 5 % and 15 % by volume. All inks had requisite rheology for material extrusion to fabricate near-net and dense components via pressureless sintering with densities of 93.95 %, 92.11 %, and 85.65 %, respectively. Micro X-ray computed tomography and deep learning auto-segmentation was utilized to fully describe the fiber orientation in 3D, revealing highly oriented fibers. 4-point flexure testing was performed on as-printed bend bars for all 3 ink compositions. The bars had robust average flexural strengths of 114–260 MPa, with a decrease in strength observed in fiber-reinforced samples as attributed to a decrease in sample density. However, an increase in Weibull modulus (18.0 compared to 7.0–7.3) and observed fiber pull out for the 15 % Cf samples suggest promise in toughening and reliability of fiber reinforcements. Oxyacetylene torch testing was performed on all 3 types of printed parts to study the oxidation and ablation resistance of the silicon carbide samples with fibers. Only samples with fiber reinforcements survived thermal shock of testing further emphasizing the need and benefit of fiber inclusions.
