摘要：
The SiO2 aerogel is a lightweight solid material containing nano mesoporous structure. The SiO2 aerogel has the characteristics of high porosity, high specific surface area, low thermal conductivity and low dielectric properties. The SiO2 aerogel has broad application prospects in the fields of heat insulation, adsorption, sound absorption, luminescence, catalysis, electronics and other industrial fields. However, porous structure of SiO2 aerogel is fragile and easy to collapse, which leads to the application being limited. The research focuses on the preparation of SiO2 aerogel composites with excellent mechanical properties, but without significantly impairing the other good properties. The main preparation process, composites performance and reinforcement mechanism of SiO2 aerogel composites reinforced by fiber, organic polymer and inorganic doping were introduced. In order to provide new design ideas for the study and application of SiO2 aerogel composites, the research progress and key directions of the reinforced SiO2 aerogel composites were discussed.
