TiSi 2 reinforced boron phenolic composites (TP) and Vitreous silica fabric reinforced TiSi 2 / boron phenolic composites (VTP) were prepared by compression molding, and their thermal, mechanical, ablation properties were studied. TG results show that thermal stabilities and residual carbon rate of boron phenolic are improved after introducing TiSi 2 particles. Compared with VTP-0 (containing 0 phr TiSi 2 ), flexural strength of VTP-60 (containing 60 phr TiSi 2 ) pyrolysis product increases by 29.5% at 1 200 ℃. Raman spectrum shows that TiSi 2 particles promote the ordering of the glass carbon structure of VTP pyrolysis product. Compared to VTP-0, the linear and mass ablation rates of VTP-60 reduce by 32.1% and 77.5%, respectively. XRD and SEM indicate the formation of an oxide coating layer, TiO 2 -SiO 2 , integrates the bulk and protects the underlying materials from damage under high temperature oxygen-containing airstream. All these results prove that mechanical properties of pyrolysis product, thermal, and ablation resistance are improved by addition of TiSi 2 particles.

Carbon fabric reinforced phenolic composites were widely used as TPSs (thermal protection system) material in the aerospace industry. However, their limited oxidative ablation resistance restricted their further utility in more serious service conditions. In this study, the surface-decorated ZrB2/SiC and its modified carbon fabric reinforced phenolic composites have been successfully prepared. The self-modification mechanism of the surface-decorated ZrB2/SiC particles were characterized. The mechanical performance and ablation behavior of the composites were investigated. Results showed that the ZrB2/SiC particles possessed a good surface-decorated effect, which achieved good compatibility with the phenolic resin. The mechanical performance of the modified phenolic composite was effectively improved. The anti-oxidative ablation performance of the composite was improved. The mass ablation rate of the surface-decorated ZrB2–SiC-modified carbon fabric reinforced phenolic composites was 25% lower than that of the unmodified composites. The formed ZrO2 ceramic layer attached to the surface of the residual chars prevented the heat energy and oxygen from the inner material. Meanwhile, the volatilization of SiO2 and B2O3 effectively increased the heat dissipation. All these results confirmed that the ZrB2–SiC particles can effectively improve the ablation resistance of the composite, which provided a basis for the application of the composites to more serious service environments.

“…The initial and terminal pyrolysis temperature of the printed sample polymer precursor is about 300 and 480 °C, which is in accordance with the results of other polymer precursors. [40][41][42][43] Considering the change of the heating rate (from 0.05 to 0.5 °C min −1 compared with 5 °C min −1 at TGA) to carbonize the electrode, a broad region from 300 to 480 °C, beyond which the mass loss rate is approaching to 0, is set as main mass loss regions. After several trials at various heating rates (Figure S1d-f, Supporting Information), a much smaller heating rate (0.05 °C min −1 ) is selected to maintain the designed shape in the carbonization.…”
