Taking silica aerogels and polytetrafluoroethylene as additives and glass fiber as reinforcement,the effects of different glass fiber content on the properties of silica aerogels/PTFE composite insulation panels were investigated.The structure and properties of the composites were characterized by FT-IR,BET and comprehensive thermal analysis.The results shown that when the glass fiber content was 1.5wt%,the overall performance of the composites was the best,and the pore diameter was 116.90nm.In addition,the density of the composites increased linearly with the increase of the amount of glass fiber.With the increase of the amount of glass fiber,the high temperature resistance of the composites became stronger and the thermal conductivity changed less and less.
