Ultra-High Temperature Ceramics: Materials for Extreme Environment Applications IV

Among ultrahigh temperature ceramics (UHTC), ZrB2-based ceramics have received the most attention for applications in the leading edge of hypersonic space vehicles. Despite significant research efforts, the development of ZrB2-SiC based ceramics in reference to performance-qualifying property assessment (shock resistance, ablation, etc.) together with the design of thermal protection system (TPS) has not been extensively reported in literature. While briefly presenting our recent research in this direction, I shall discuss myriad of opportunities and challenges ahead in TPS design for hypersonic space vehicles.

To begin with, results of the carefully designed experiments using innovative multi-stage spark …
