What is Fabrication of high‐strength porous SiC‐based composites with unidirectional channels about?
## Abstract Carbon fiber reinforced SiC‐based composites with unidirectional channels were obtained by freeze‐casting and chemical vapor infiltration techniques, and their microstructure and fracture behavior were investigated. The results indicated that the sizes of the unidirectional channels could be controlled in the 15‐70 μm range. The significant pseudo plastic and ductility features of the porous SiC‐based composite were demonstrated during the fracture process. The strains of the composites reached 4 ± 1% and 50 ± 6% during bending and compressive experiments, respectively. The bending and compressive strengths, 123 ± 20 and 99 ± 15 MPa, respectively, were far superior to those of homogeneous ceramics presenting the same porosity. Combining the aforesaid method with 3D printing techniques, a SiC‐based composite part with controlled macro‐micro channels was fabricated, which indicated that this method could be useful for fabricating ceramic parts with complex structure and superior mechanical performance.
