Abstract

In order to improve the high-temperature resistance and thermal insulation of SiC nanofiber aerogel, the structural design and preparation of SiC nanofiber composite aerogel felt were carried out based on the heat transfer mechanism. A novel multi-layer SiC nanofiber aerogel felt was prepared with the ablative layer (ZrO₂/ZrSiO₄ anti-oxidation layer), opacifiers layer (TiO₂ and SiC), and heat insulation layer (SiC nanowire aerogel). Compared with the single SiC nanowire aerogel, the oxidation resistance temperature of SiC nanofiber composite aerogel felt increased from 1300 ℃ to 1500 ℃ during aerobic calcination. With the butane gun ablation, the back temperature of the single SiC nanofiber aerogel felt was 308 ℃, while the back temperature of the composite aerogel felt was only 130 ℃. The structural design of the multi-layer SiC nanofiber composite aerogel felt provides an approach to improving thermal insulation properties in extreme environments.

期刊介绍： The Journal of the European Ceramic Society publishes the results of original research and reviews relating to ceramic materials. Papers of either an experimental or theoretical character will be welcomed on a fully international basis. The emphasis is on novel generic science concerning the relationships between processing, microstructure and properties of polycrystalline ceramics consolidated at high temperature. Papers may relate to any of the conventional categories of ceramic: structural, functional, traditional or composite. The central objective is to sustain a high standard of research quality by means of appropriate reviewing procedures.
