Nondestructive characterization of high-performance C/SiC-ceramics using X-ray-computed tomography
Abstract
The quality control of ceramic matrix composites (CMC) has always been a challenge due to their anisotropy and inhomogeneity. Using high-resolution X-ray computed tomography, these materials can be analyzed in situ during the manufacturing process, providing a three-dimensional analysis without damaging or modifying the samples. This paper analyzes the three material states CFRP, C/C and C/SiC that occur during the processing of melt-infiltrated C/SiC composites and describes the changes in morphology occurring after each processing step. In addition, a quantitative porosity and phase-analysis of the complete volume was performed.
