| Abstract Scope |
Field Assisted Sintering presents significant challenges in the processing of complex and near net shape ceramic materials due to the lack of robust digital tools for predicting part consolidation. This research aims to develop a data-informed machine learning model to predict the initial part shape necessary for achieving the desired final sintered state. The work focuses on the pseudo-isostatic sintering of 3D printed preforms using a removable pressure transfer media via EFAS, with characterization of the parts performed using x-ray computed tomography and laser scanning. Additionally, unique 3D printed continuous carbon fiber carbon matrix composites were fabricated and co-sintered with SiC and B4C ceramics whereby their sintering behavior, microstructure, and basic mechanical properties, with particular emphasis on the CTE engineering of the ceramic/composite interface, will be discussed. |
