Abstract CNTs have been introduced into C/C composites by electrophoretic deposition to improve their ablation performance. Mass ablation of C/C composites decreases by 64% with an optimized CNT content. Mechanical exfoliation is mainly responsible for the mass loss of C/C composites under oxyacetylene ablation as confirmed by SEM observations and static oxidation experiments. By applying CNTs with an optimized content, thermal conductance of the composites increases by 24.5% and the fiber-matrix interfacial strength increases by 74.6%. Local thermal damage is significantly relieved and matrix peeling off by high-velocity gas is inhibited, which lead to the significant decrease of mechanical ablation.

碳纳米管的电泳沉积以提高碳/碳复合材料的耐烧蚀性

摘要 CNTs 已通过电泳沉积引入 C/C 复合材料中以提高其烧蚀性能。随着碳纳米管含量的优化，C/C 复合材料的质量烧蚀减少了 64%。SEM观察和静态氧化实验证实，机械剥离是氧乙炔烧蚀下C/C复合材料质量损失的主要原因。通过应用优化含量的碳纳米管，复合材料的热导率增加了 24.5%，纤维-基质界面强度增加了 74.6%。显着减轻局部热损伤，抑制高速气体引起的基体剥离，从而显着降低机械烧蚀。
