Carbon fiber reinforced carbon matrix (carbon/carbon, C/C) composites have become the promising candidates for high‐temperature thermal structure materials in aerospace fields, owning to a series of excellent structural merits. However, for aculeate or thin‐walled C/C composites, due to the fact that continuous carbon fibers are cut off during the machining process and the amount of residual carbon fibers is limited, carbon matrix cannot be effectively strengthened just by using carbon fibers, resulting in a sharp decline in mechanical performance. Furthermore, the rapid development of aerospace vehicles requires that C/C composites not only have excellent mechanical properties but also possess multifunctional properties. To effectively solve these problems and meet the increasing demands, various 1D nanostructures as nanoreinforcements have been introduced into C/C composites, achieving the great improvement in mechanical and functional properties. In this review, the state‐of‐the‐art research activities regarding different 1D nanoreinforcements applied in C/C composites are systematically summarized. Finally, this review is concluded and the future research prospects are proposed. This review provides the “1D nanoreinforcements” strategy to further improve the properties of C/C composites, which could be widely used for reference by researchers in the fields of different fiber/matrix composites.
