Abstract:With the rapid development of science and technology, new aerospace equipments put forward new requirements for high temperature thermal protection, thermal structure and multi-function materials, which also bring new opportunities for the research and application of carbon/carbon (C/C) composites. In this paper, the recent progress of unltra-high thermal protection C/C, thermal structural C/C, high thermal conductivity C/C, non-ablation low density C/C composites are respectively reviewed. Finally, the existing problems of several C/C composites are discussed, and the development trend in the future is also put forward.
