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 three-dimensional 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. |
