The effect of temperature on the infrared spectral emissivity of C/SiC composites as a thermal protection material has been studied, using a measurement system based on a FT-IR spectrometer. The spectral emissivity of C/SiC composites in the wavelength range 3-20 μm and in the temperature range from 1000 K to over 2000 K was measured. Based on the analysis of the measured spectral emissivity, variations of the spectral emissivity with temperature were studied. The relationship between emissivity and temperature in some certain wavelength was found.
