Carbon‐bonded carbon fiber (CBCF) composites are promising lightweight and high efficient thermal insulators to be applied in aerospace area, but their practical applications are usually restricted by the low mechanical performance and poor oxidation resistance. To overcome these drawbacks, many efforts have been made in the fabrication of ceramic coated CBCF composites. However, the densities of these modified composites are usually very high, which would result in the reduction in their thermal insulation performance. Herein, we prepared a CBCF composite with SiC nanowires enhanced interfibrous junctions and SiOC ceramic coated carbon fibers (SiCNWs‐SiOC‐CBCF). Similar to CBCF, the SiCNWs‐SiOC‐CBCF exhibits a low density of 0.35 g/cm3 and an anisotropic and highly porous architecture. The SiCNWs‐SiOC‐CBCF possesses a compressive strength of 3.8 MPa and a compression modulus of 195.7 MPa in the X (or Y) direction, ~26.7% and 150% higher than those of CBCF respectively. It can also suffer from an isothermal treatment in air at 900°C for 120 minutes. The combination of these properties makes the SiCNWs‐SiOC‐CBCF a good candidate for thermal insulator to be applied in extreme conditions.

“…Consequently, the unique properties of CBCFs have resulted in a prominent class of lightweight materials for thermal insulation . To improve the mechanical and oxidation resistance properties of the CBCFs, intense research efforts have been conducted such as modification of CBCFs via SiOC ceramic, in‐situ grown SiC nanowire (SiC nw ), and fabrication multi‐composition anti‐oxidation layers . The oxidation resistance capability is a key property in the overall performance, which can protect the thermal protection system in an environment containing oxygen at high temperature (>400°C) .…”

To enhance the oxidation resistance capability of the carbon‐bonded carbon fiber composites (CBCFs), a silicide ultra‐thick coating as high as 1.6 mm with gradient structure is designed and fabricated via a multi‐step rapid sintering method. Compared with other ceramic layers on carbon fiber‐based composites, ultra‐thick anti‐oxidation layer coated‐CBCFs have the lowest thermal conductivity. Additionally, ablation behaviors of the ultra‐thick ceramics layer coated‐CBCFs under the oxyacetylene torch are also investigated. After being exposed to oxyacetylene torch, the ultra‐thick ceramics layer coated‐CBCFs possess a linear rate range from 0.6 to 1.2 μm/s, while a mass ablation rate ranges from 4.95 × 10−5 g/m2 s to 1.45 × 10−3 g/m2 s.

An oxidation resistant coating for highly porous carbon-bonded carbon fibre composites (CBCFs) was prepared by slurry method. The compositionally and structurally gradient coating consists of a carbon fibre reinforced SiC inner layer, a SiC with CaO-MgO-Al 2 O 3 -SiO 2 (CMAS) glass inter layer, and a dense CMAS glass outer layer. The effectiveness of the S-SG-G coating in protecting the CBCFs from degradation at 1000 °C in air has been evaluated. The results indicated that the coating could protect CBCFs from oxidation for 100 min with the weight loss of 20.7%. In contrast, the uncoated CBCFs were completely combusted after 50 min. Good oxidation resistance of the coating is mainly attributed to high temperature stability of SiC, CMAS glass sealant, and good adhesion within the coating layers and with the substrate.
