Effects of porous C/C density on the densification behavior and ablation property of C/C–ZrC–SiC composites

Effects of Cf/C density on microstructure and properties of 3-D Cf/ZrC composites prepared by liquid metal infiltration

“…and 3D C f /SiC-ZrC composites (13.6 [25], 2.48 [26] and 2.79 µm s -1 [27]), exhibiting an excellent ablation resistance in high-temperature oxidizing environment. However, the mass loss rates are relatively higher, which might be caused by the evaporation of Cu.…”

Microstructure and ablation behavior of C/C–HfC composites prepared by precursor infiltration and pyrolysis

“…Verdon et al prepared hafnium and silicon carbide multilayer coatings for the protection of carbon composites by low pressure chemical vapor deposition (LPCVD) [20]. Precursor infiltration and pyrolysis (PIP) process, which has been employed to prepare C/C-UHTCs composites, ease the fabrication of materials with complicated shapes and ceramic particles with uniform dispersity into C/C-UHTCs composites [21]. Up to now, C/C-HfC composites have not been reported by PIP.…”

Residual thermal stresses in carbon/carbon–Zr–Ti–C composites and their effects on the fracture behavior of composites with different preforms

“…Some refractory metal carbides and borides, such as ZrC [1], ZrB 2 [2], SiC [3] and their composite ceramics [4][5][6][7], have been introduced into continuous carbon fiber preforms to improve the ablation resistance and thermal shock resistance of carbon-ceramic-based composites that were used in applications such as the heat-stable components of aerospace vehicles and aircraft brakes. However, the difference in the coefficients of thermal expansion (CTEs) between the ceramics and the carbon matrices, such as carbon fiber and pyrocarbon (PyC), is significant.…”
