Abstract Carbon fiber reinforced carbon matrix containing ZrC (C/C–ZrC) composites were prepared by hydrothermal deposition combined with carbothermal reduction. The submicron ZrC particles (100–300 nm) were dispersed in the matrix. The stress-strain curves of the composites presented a typical pseudo-plastic fracture behavior. The mass and linear ablation rates of the composites were 3.7 × 10−3 g/s and 4.2 × 10−3 mm/s, respectively. The formation of ZrO2 glass layer reduced erosion of the composites in the ablation center. The continuous C–ZrC–ZrO2 skeleton layer generated from the oxidation of ZrC can protect the composites from erosion at the ablation brim region. The obtained C/C–ZrC composites present a promising potential as ablation resistance materials.

水热沉积结合碳热还原制备的C/C-ZrC复合材料的显微结构和性能

摘要 通过水热沉积结合碳热还原制备了含 ZrC 的碳纤维增强碳基体（C/C-ZrC）复合材料。亚微米 ZrC 颗粒（100-300 nm）分散在基体中。复合材料的应力-应变曲线呈现典型的假塑性断裂行为。复合材料的质量和线性烧蚀率分别为 3.7 × 10−3 g/s 和 4.2 × 10−3 mm/s。ZrO2 玻璃层的形成减少了烧蚀中心复合材料的侵蚀。ZrC 氧化产生的连续 C-ZrC-ZrO2 骨架层可以保护复合材料免受烧蚀边缘区域的侵蚀。获得的 C/C-ZrC 复合材料作为抗烧蚀材料具有广阔的前景。
