| Abstract Scope |
A significant amount of work in recent years has focused on the use of preceramic polymer feedstocks filled with structural and/or functional fillers such as carbides, nitrides, and other carbon fillers. Such work provides a foundation and opportunity for new material formulation and additive manufacturing (AM) process development that we aim to build upon. In this work, we utilize the AM process of direct-ink writing, coupled with implementation of a novel co-extrusion, core-shell printhead, to fabricate hybrid polymer-derived ceramic composites with a core-shell motif to achieve unique structural and functional properties. Specifically, this talk will focus on the creation and characterization of electrically conductive and insulating polysilazane-derived materials to enable AM of high temperature sensors and related applications. Rheological characterization, printing behavior, and post-pyrolysis properties will be highlighted, and challenges with co-processing in the core-shell motif will be discussed. |
