Abstract Scope Ultra-high temperature ceramics (UHTC) are a class of materials that are used for aerospace applications because of their high melting temperatures and ablation resistance. This study focuses on increasing chopped carbon fiber loading in both ZrB2 and SiC –based inks to improve fracture toughness. By using direct ink writing (DIW), a gradient of the carbon fiber is printed to minimize fibers at the surface. The effect of varied concentrations of the carbon fibers on the rheology and printability of the different inks is investigated. The different carbon fiber loadings and gradated ceramics are evaluated with oxyacetylene torch testing to study oxidation and ablation resistance. The change in fiber orientation with respect to fiber loading is analyzed by using X-ray computed tomography as a function of the matrix ceramic.
