Abstract

This study presents the findings of in-situ synchrotron studies on high temperature ceramic matrix composites. The application of high intensity synchrotron X-Rays characterization of ceramic matrix composites has shown great promise to unlock complex material behavior in response to extreme conditions. Synchrotron studies provide micron resolution examination of material behavior and performance. This study utilized synchrotron radiation to conduct 3D Computed Tomography and 2D diffraction on an all-alumina ceramic matrix composite (WHIPOX™) under extreme environments. Quasi-unidirectional composites with varying fiber orientation were investigated to identify load partitioning between the fibers and matrix, and the influence of specimen aging compared with the as processed composite. Radiography and Diffraction studies were conducted on specimens under compression loading and extreme temperatures. Results show segregation of fiber and matrix diffraction rings under loading and distinct texturing variation due to grain size and growth. In-situ strain analysis provides insight into mechanical properties of matrix material and the varying fiber orientation composites, while computed tomography sheds light on macro-porosity and the role of processing. Together the synchrotron studies provide valuable material information on the structural capability of these ceramic matrix composites.
