| Abstract Scope |
The polymer derived ceramics (PDCs) route presents a flexible and energy-efficient approach to fabricate a broad spectrum of ceramic composites with arbitrary geometries and tailorable properties. Currently, however, a lack of knowledge about how atomic-level structural change affects the evolution of continuum-level phase composition—as well as the poor linkage among the process physics, material response, and key processing parameters—have kept our ability to tailor PDC properties to the level of trial and error. A computational framework that predicts continuum-scale ceramic phase formation from atomic-scale structure evolution is presented. The interplay between gas generation and gas diffusion, as well as its role on ceramic phase formation, is systematically studied. The computational model, which elucidates the intricate coupling between heat transfer and phase transition by resolving real-time temperature field and phase composition map, allows key mechanical properties to be predicted at any pyrolysis state. |
