| Abstract Scope |
Ultra-high temperature ceramics (UHTCs) have garnered a great deal of interest as materials for extreme environments, but are challenging to process into complex components and ceramic matrix composites (CMCs). Preceramic polymers (PCPs) are one potential solution due to their unique ability to be converted from a workable polymeric material that can be processed into complex shapes and components, to a ceramic via heat treatment. Though PCPs are attractive for creating ceramics and composites, the vast majority of PCPs are silicon-based. This presentation will discuss a family of novel preceramic polymers that can form UHTCs carbides and nitrides. Along with creating a wide range of UHTC carbides and nitrides, these preceramics are inherently flowable, generate inorganic products in high yield (i.e., ≥50 wt%), can produce phase pure ceramics without excess carbon, and have tailorable compositions and rheology. This presentation will discuss the processing of these AFPCs into CMCs. |
