“…. The thickness of SiC layer could be expressed by 30 :

where δ is the thickness of SiC layer, m , ρ is the density of SiC, kg/m 3 , D is the diffusion coefficient of Si through SiC layer, m 2 /s, C Si,l is the density of Si in the liquid phase, kg/m 3 , and t is the reaction time, s .

Carbon fiber reinforced ceramic matrix composites (C/C‐SiC composites) were fabricated using a type of high‐char‐yield phenolic resin with the char yield of 81.17 wt.%. Firstly, the fabric prepreg was prepared by spreading the phenolic resin solution onto the two dimensional carbon fiber plain weave fabric and dried consequently. Afterward, the resin was cured and then the carbon fiber reinforced polymer (CFRP) was pyrolyzed to get amorphous carbon. Finally, C/C‐SiC composites were obtained through liquid silicon infiltration (LSI) process. SEM micrographs showed that the Si/SiC area was homogeneously dispersed in the matrix, and during the siliconization process, a layer of SiC was formed along the surface of carbon fibers or carbon matrix. The fiber volume of CFRP was about 40 vol.%, which was much lower than other studies. XRD result indicated that only β‐SiC type was formed. The result of X‐ray computed tomography clearly showed the structure changes before and after the melt infiltration process. Mechanical property test showed that the composites had fracture strength of 186 ± 23 MPa, and a flexural modulus of 106 ± 8 GPa.

“…The introduction of carbon fibers in TiC ceramics has been shown to greatly improve their mechanical and thermal shock properties. Short carbon fiber-reinforced TiC composites, 2D C f /C-TiC, and 3D C f /C-TiC composites have been prepared using hot pressing (HP), chemical vapor infiltration (CVI), and RMI, respectively [12][13][14][15]. The results showed that the mechanical properties of TiC were greatly improved due to the introduction of carbon fibers.…”

In this work, chemical vapor infiltration (CVI) was combined with reactive melt infiltration (RMI) using Ti–6Al–4V titanium alloy powder to prepare Cf/C–TiC composites. The microstructure and composition of Cf/C–TiC composites were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The flexural properties of the composites were also analyzed. The results indicated that the Ti–6Al–4V titanium alloy infiltrated the Cf/C preform and reacted with the pyrolytic carbon (PyC) to form a TiC–VC and Al4C3 matrix, and no residual Ti, Al, or V was detected. Moreover, Al4C3 was concentrated and independently distributed, whereas Ti and V reacted with C to form a TiC–VC solid solution. The porosity was 6.75%, and the bulk density of Cf/C–TiC was 1.96 g/cm3. The flexural strength, flexural modulus, and failure strains were 256 ± 18 MPa, 89 ± 9 GPa, and 0.93 ± 0.13%, respectively. The work of fracture of the Cf/C–TiC composite was about 6.8 ± 0.38 KJ/m2. Due to the propagation and deflection of cracks, as well as debonding and fiber pullout, the Cf/C–TiC composite showed ductile fracture behavior.
