Morphological Evolution and Internal Strain Mapping of 2.5d-C/Sic Composite Materials Under Laser Load Using X-Ray Computed Tomography and Digital Volume Correlation

In the field of active thermal protection in aerospace, the research on C/SiC composites as transpiration cooling porous materials has garnered increasing attention. This paper examines the microstructural evolution behavior of 2.5D-C/SiC composites under laser load, employs DVC technology to analyze the stress-strain characteristics of thermal deformation within the material’s microstructure, and investigates the impact of microstructural evolution on the transpiration cooling properties of 2.5D-C/SiC composites. The research findings indicate that image pixel grayscale values obtained via CT scanning can qualitatively assess changes in the composition of 2.5D-C/SiC composites. The evolution process of the microstructure of 2.5D-C/SiC composites can be analyzed using in-situ CT scanning and DVC technology. The impact of microstructural evolution on the transpiration cooling performance of 2.5D-C/SiC composites is significant.
