Abstract

The total hemisphere emissivity (ε_H) at 90°C and the normal spectral reflectance at room temperature of 3D C/SiC composites were measured with the steady-state calorimeter method and FTIR, respectively. The effects of the surface morphology, thickness of SiC coating and high temperature oxidation on the thermal radiation properties of 3D C/SiC were investigated. The results show that 3D C/SiC composites have excellent thermal radiation properties and the total hemisphere emissivity attains 0.83. With increasing the SiC coating thickness, the total hemisphere emissivity of 3D C/SiC composites decreases first and increases then. After oxidation, the thermal radiation properties of 3D C/SiC with three character surface remarkably increase.
