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.
