Carbon fiber[CF]/pyrolytic graphite[PG]composites are promising structural materials for molten salt reactors because of their superior performance.Due to the minor density difference between CF and PG,existing methods are impractical for efficient three-dimensional characterization of CF/PG composites.Therefore,in this study,a method based on in-line phase-contrast X-ray microtomography was developed to solve the aforementioned problem.Experimental results demonstrate that the method is suitable for comprehensive characterization of CF/PG composites.The relationship between the micro-porous defects and fiber orientations of such composites was also elucidated.The findings can be useful for improving the manufacturing process of CF/PG composites.
