新型耐超高温轻质防隔热一体化材料设计、构筑及热致损伤行为评价

This project focuses on the key fundamental and scientific problem for design, microstructure building, and thermally induced damage of novel integrated thermal protection systems (TPS). Typically, we will carry on the research of novel integrated carbon tiles-ceramic tiles TPS systematically. The main research contents concerns microstructural design, total thermal transfer, thermal-mechanical coupling and experimental identification. We will acquire the following researching achievements: (1) Experimental optimization at macro- and micro-scale for novel thermal-insulation integrated TPS; (2) Comprehensive thermal transfer characteristics at micro- and meso-scale for highly porous fibers in thermal-insulation integrated TPS; (3) Thermal-mechanical coupling simulation for integrated multilayered TPS structure; (4) Experimental identification, thermal failure mechanism and comprehensive performance evaluation. The research achievements of this project will supply research foundation and technical surpport for such thermal-insulation integrated TPS in the field of reuseable hypersonic vehicle.
