| Abstract: | Due to unique nano-porous structure, silica aerogel possesses the characteristics of low density and low thermal conductivity, which make it a potential highly efficient thermal insulation material. However, poor mechanical properties greatly inhibits its applications. Recently in the field of effective insulation material, inorganic fibers reinforced silica aerogel composites have become an international hot issue because of their excellent mechanical and thermal insulation properties. The preparation method and research progress of inorganic fibers reinforced silica aerogel insulation composites are summarized. In addition, the further prospects are presented. |
