摘　　要：C/C三维纺织复合材料因其可设计性强、力学性能优异和耐高温等特点而被广泛地应用于航空航天、轨道交通和光伏热场等高温端部件。然而,C/C三维纺织复合材料内部纱线结构复杂且孔隙率高,呈现出高度各向异性和非均匀性,这些因素都会给力学性能及损伤机制揭示带来巨大困难。因此,本工作从实际应用出发,围绕C/C三维纺织复合材料,从细观重构、力学性能表征和数值模拟三个方面阐述近几年的国内外研究现状,并在此基础上重点对C/C三维纺织复合材料结构功能一体化制备、深度学习模型的发掘和高温实验环境下渐进损伤实验平台的搭建做出了展望。Carbon/carbon(C/C)three-dimensional textile composites are widely used in aerospace,rail transit,photovoltaic thermal field and other high temperature components due to their strong designability,excellent mechanical properties and high temperature resistance.However,the internal yarn structure of C/C three-dimensional textile composites is complex and has high porosity,showing a high degree of anisotropy and heterogeneity.These factors will bring great difficulties in revealing the mechanical properties and damage mechanism.Therefore,starting from practical applications,the research status of C/C threedimensional textile composites is reviewed in recent years from three aspects:micro reconstruction,mechanical performance characterization,and numerical simulation.The aim is to provide important support for the integrated preparation of C/C three-dimensional textile composites structure and function,the exploration of deep learning models,and the construction of progressive damage testing platforms in high-temperature experimental environments.
