“…The surface XRD pattern of ablated C‐Ph/ZrO 2 /SiC 0.25 composite was carried out to investigate the presence of ZrC and SiO 2 . In Figure , it can be observed that the composite is consist of SiO 2, C, ZrO 2, SiC, and ZrC, which indicates that zirconium‐containing matrix and poly‐carbosilane have completely reformed into ZrC during the pyrolysis process . The effectiveness of the ceramic phase and bubble‐like structure to ablation performance was further enhanced with increasing the content of SiC in the composite.…”

“…It can be seen that SiO 2 bubbles formed on the C‐fibers during the themo‐mechanical ablation process. When the composite sample was subjected to the flame environment, the SiC was oxidized to SiO 2 through following Equations and

In this study, an effort has been made to improve the mechanical, thermal, and ablation performance of carbon-phenolic (C-Ph) composites. The ZrO 2 , SiC, and ZrO 2 /SiC hybrid fillers were synthesized using sol-gel method followed by individual incorporation into C-Ph composites. The thermal stability and flexural strength of these C-Ph composites were analyzed using thermogravimetry analysis and three-point bending test, respectively. A significant improvement in the flexural strength and modulus of the reinforced C-Ph composites was observed and also exhibited the higher thermal stability. The oxyacetylene flame test was conducted to measure the ablation behavior of these filler reinforced C-Ph composites under a heat flux of 4.0 MW/m 2 for 60 seconds. ZrO 2 /SiC0.5 reinforcement in the C-Ph composite decreased the linear and mass ablation rates by 46% and 22%, respectively when compared with pure C-Ph composite. The surface morphology analysis revealed that the burnt composite covered with the ZrC ceramic phase and SiO 2 bubble-like structure, which could have improved the ablation resistance of composites. These results were found well within the acceptable range when using the surface energy dispersive spectroscopy and X-ray diffraction analysis.

“…The residual holes and cracks would provide diffusion paths of oxygen and thus accelerate the oxidation of the composite. The other is active oxidation of SiC above 1800℃ [14], which would cause severe depletion of SiC and leave a porous ZrO 2 oxide scale on the ablated surface [3,10,12,15]. However, the porous ZrO 2 can hardly inhibit the diffusion of heat and oxygen into the composites and will be easily peeled off in thermal shocks.…”

To improve anti-ablation property of C/C-ZrC-SiC composite, a novel design of Al-Cr alloy surface sealing was performed by liquid melt impregnation. Results show that Al 8 Cr 5 formed on the surface which could effectively seal the holes and cracks. The cooperation of metal and ceramics contribute a better anti-ablation performance to the obtained composite, and its mass and linear ablation rates decrease by 98.3% and 81.2% respectively. This special surface structure evolves into a highly dense oxide scale comprising various solid solutions(including Al-Cr-O, Al-Si-O, Cr-Si-O) and ZrO 2 , which could significantly improve the anti-ablation performance of C/C-ZrC-SiC composite.

“…However, when its service temperature above 2500 °C, the protective oxide layer is porous, which loses its properties of oxidation resistance and anti-ablation ultimately. Because the self-healing SiO2 melt is washed away by high-speed airflow or even evaporated [9,10], original micro-cracks, pores, and porous ZrO2 generated during the ablation will not be filled [11,12]. In addition, some carbon fibers are exposed on the composites surface prepared by reactive melt infiltration, which are preferentially oxidized to generate micro grooves.…”

Neoteric “Z-pins like” vanadium0.9-silicon0.1 rods (V0.9-Si0.1 rods) as polybasic multiphase oxide compensators were prepared to improve the anti-ablation of C/C-ZrC-SiC over 2500 °C. The microstructure and improvement effect on the anti-ablation of different C/C-ZrC-SiC surface were investigated. Results show that the density of “Z-pins like” V0.9-Si0.1 rod was effectively improved after adding Si. When ablation time was less than 180 s, “Z-pins like” V0.9-Si0.1 rods perpendicular to non-woven cloth layer presented the best improvement of the anti-ablation performance by liquid/gaseous multicomponent oxide compensation. However, when ablation time was greater than 180 s, “Z-pins like” V0.9-Si0.1 rods perpendicular to non-woven cloth layer increased another harm that weaken the anti-ablative performance of C/C-ZrC-SiC, namely, the corrosion damage of oxide layer on the matrix surface caused by excessive oxide melt. Therefore, there is a best improvement of the anti-ablation performance of “Z-pins like” V0.9-Si0.1 rods parallel to non-woven cloth layer.
