Oxidation and ablation behaviours of a SiCnw@SiC–Si coating fabricated for carbon-fibre-reinforced carbon-matrix composites via thermal evaporation and gaseous silicon infiltration

Yttrium Silicate‐Coated Carbon Fiber Reinforced Phenolic Aerogel‐like Composites with Low Density and Low Ablation

“…The temperatures of the ablated surface and back face are measured by an infrared thermometer and thermocouples, respectively. The mass and linear (R m , R l ) ablation rates are calculated, respectively, as follows: [18,19] $$$\vcenter{\openup.5em\halign{$\displaystyle{#}$\cr \ {R}_{m}={{\Delta m}\over{t}}\hfill\cr}}$$$ $$$\vcenter{\openup.5em\halign{$\displaystyle{#}$\cr \ {R}_{l}={{\Delta h}\over{t}}\hfill\cr}}$$$ …”

Fabrication and Ablation Properties of SiC Nanowires-Network Modified Carbon/Carbon–Ultrahigh Temperature Ceramics Composites

“…Furthermore, during oxidation, a molten silica scale glass can be formed, which can endow the composites with a good self-healing effect against cracks [27,28]. Therefore, there is a strong possibility that the CTE mismatch and self-healing problems of C/C-UHTCs composites can be solved if we fully utilize the properties of SiCnws and the UHTCs matrix synergistically [29][30][31]. If a ceramic matrix dispersed with SiCnws interwoven networks can be obtained, it can not only alleviate the CTE mismatch between C/C and the UHTCs to reduce the cracks formation, but also increase the length per unit area of the UHTCs/SiC interface and provide molten glass SiO 2 continuously during oxidation.…”
