“…To further improve the ablative resistance of C/SiM composites in complex and extreme circumstances, other transition metals except from Zr, such as Ta, Hf, Y, Ti, Mo, Cr, La, etc., are also incorporated into the C/SiM composite [ 164 , 165 , 166 , 167 , 168 ], which is called a C/SiZM composite (Z=Ta, Hf, Y, Ti, Mo, Cr, La, etc.). Table 3 showcases recent ablation and oxidation properties of C/SiZM composites and provides a summary of both historical and recent ablation research results of C/C-SiC-Z composites.…”

Composites with excellent thermomechanical and thermochemical properties are urgently needed in the aerospace field, especially for structural applications under high-temperature conditions. Carbon fiber-reinforced Si-based composites are considered the most promising potential high-temperature materials due to their excellent oxidation resistance and ablative behaviors, good structural designability, and excellent mechanical properties. The reinforcement of the relevant composites mainly involves carbon fiber, which possesses good mechanical and temperature resistance abilities. In this paper, the ablation behaviors and mechanisms of related composites are reviewed. For carbon fiber-reinforced pure Si-based composites (C/SiM composites), the anti-ablation mechanism is mainly attributed to the continuous glassy SiO2, which inhibits the damage of the substrate. For C/SiM composite doping with refractory metal compounds, the oxides of Si and refractory metal together protect the main substrate from ablation and oxidation. Moreover, in addition to thermochemical damage, thermophysical and thermomechanical behavior severely destroy the surface coating of the substrate.

“…[19,20] The development of an efficient and low-cost fabrication technology for SiC/Al composites can promote their large-scale applications. [21] Although many studies focusing on the fabrication of SiC/Al composites have been reported, [18,20,[22][23][24] only few studies have reported the effect of high-content SiC/Al composites on the characteristics of the SiC gradient distribution. Zhou et al [25] used the filtration extrusion method to fabricate an Al/diamond electronic packaging material with up to 40 wt% diamond content.…”

Functionally graded materials (FGMs) have broad application prospects owing to their outstanding material properties. Herein, a filtration extrusion device is designed, and low‐content SiC/Al composites are used to explore the feasibility of applying filtration extrusion techniques to the fabrication of FGMs. The results suggest that the extrusion force increases monotonically with an increase in the filtration extrusion ratio. Furthermore, the filtration extrusion process can be divided into two stages based on the change trend of extrusion pressure: at stage 1, extrusion force is small and increases slowly. At stage 2, the extrusion force increases significantly and rapidly. During the filtration extrusion process, the larger the initial content, the lower the extrusion temperature, the smaller the hole‐separation mold area ratio, the faster the increase in the extrusion force, and the greater the maximum extrusion force during the extrusion process. Based on filtration extrusion experiments for various extrusion distances, it is found that the transition from the nonflow to the flow influence zone is primarily responsible for the enrichment and gradient distribution of SiC particles. The SiC particles are distributed in a gradient, and the content of SiC particles near the separation mold is higher than that on the other side.

“…Continuous fiber-reinforced ceramic matrix composites (SiC f /SiC [ 7 ], SiC f /C [ 8 ], C f /C [ 9 ], C f /SiC [ 10 ], and SiC f /AlPO 4 [ 11 ]), showing excellent fracture toughness, good thermal stability, and environmental durability, have been evaluated and modified for use as structural electromagnetic wave-absorbing materials. Especially, continuous SiC fiber-reinforced AlPO 4 (SiC f /AlPO 4 ) composites have demonstrated good potential [ 12 , 13 , 14 ].…”

The Influence of SiO2 + SiC + Al (H2PO4)3 Coating on Mechanical and Dielectric Properties for SiCf/MWCNTS/AlPO4 Composites

et al. 2022

SiC fiber-reinforced AlPO4 matrix (SiCf/MWCNTs/AlPO4) composites were fabricated using a hot laminating process with multi-walled carbon nanotubes (MWCNTs) as the absorber. A coating prepared from SiO2 + SiC + Al (H2PO4)3 was applied to the surface of the SiCf/MWCNTs/AlPO4 composites prior to an anti-oxidation test at 1273 K in air for 40 h. The anti-oxidation effect was verified by a three-point bending test, scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and a dielectric property test. Anti-oxidation mechanism investigations revealed that the coating effectiveness could be attributed to three substances, i.e., SiO2, SiP2O7, and SiO2 + AlPO4 solid solution from the reactions of SiC + O2→SiO2 + CO, SiO2 + P2O5→SiP2O7 and SiO2 + AlPO4→solid solution, respectively.
