C/SiC composites, regarded as a new generation of thermal structural materials, have many excel-lent properties, such as low density, high speciifc strength and elastic modulus, high thermal conductivity, low coefifcient of thermal expansion, good abrasive resistance, and high thermal stability. C/SiC composites have been applied in many ifelds, including space optical system, thermal protection system of space vehicle, and brake materials. In this paper, firstly, the excellent properties and fabrication methods of C/SiC composites are introduced, and the key point is paid into the design and optimization of preparation of C/SiC composites by gaseous Si infiltration. Finally, the challenges for C/SiC composites that will be met in the future are put forward.
