| Abstract Scope |
Polymer-derived ceramics (PDCs) are rapidly emerging as a key material system for the manufacturing of ceramic matrix composites (CMCs). While the polymer-to-ceramic conversion process has been widely studied, comparatively little attention has been given to the subsequent high-temperature evolution of the resulting ceramic phase. In particular, the development of density and crack networks plays a critical role in determining the structural performance of these materials. In this work, the density of several PDC systems is quantified using image analysis of in-situ µCT data. In addition to density measurements, the evolution of internal features is tracked in-situ during densification, enabling direct correlation between densification behavior and microstructural changes. This methodology provides a powerful framework for evaluating not only the polymer-to-ceramic transformation of emerging PDC compositions, but also the dynamic evolution of their microstructure following ceramic phase formation. |
