“…Adams et al [18] and Manocha et al [4] analyzed the microstructure and thermophysical properties of C MP /C composite. Although much data has been reported in the literature on the fabrication of high-thermal-conductive C MP /C composite [18] and there has been evaluation of the thermophysical properties [19,20] and analysis of the thermal conductivity mechanism [21,22], there have been few reports on the ablation behavior of C MP /C composite, which is worth exploring. It is known that the microstructures and properties of CF MP and CF PAN are evidently different.…”

This study is focused on a novel high-thermal-conductive C/C composite used in heat-redistribution thermal protection systems. The 3D mesophase pitch-based carbon fiber (CFMP) preform was prepared using CFMP in the X (Y) direction and polyacrylonitrile carbon fiber (CFPAN) in the Z direction. After the preform was densified by chemical vapor infiltration (CVI) and polymer infiltration and pyrolysis (PIP), the 3D high-thermal-conductive C/C (CMP/C) composite was obtained. The prepared CMP/C composite has higher thermal conduction in the X and Y directions. After an ablation test, the CFPAN becomes needle-shaped, while the CFMP shows a wedge shape. The fiber/matrix and matrix/matrix interfaces are preferentially oxidized and damaged during ablation. After being coated by SiC coating, the thermal conductivity plays a significant role in decreasing the hot-side temperature and protecting the SiC coating from erosion by flame. The SiC-coated CMP/C composite has better ablation resistance than the SiC-coated CPAN/C composite. The mass ablation rate of the sample is 0.19 mg·(cm−2·s−1), and the linear ablation rate is 0.52 μm·s−1.
