Aerogel composite material and method of manufacturing aerogel composite material, and method for treating aerogel powder

A method of manufacturing an aerogel composite material comprising a porous fiber material;

• and a preheated aerogel powder, wherein the method comprises:
• impregnating the pre-heated aerogel powder into the porous fiber material by applying an alternating electric field,
• wherein a voltage of the alternating electric field ranges from about 0.1 KV to about 200 KV;
• wherein a frequency of the alternating electric field ranges from about 0.1 HZ to about 800 HZ;
• wherein the aerogel powder has a density ranging from about 0.01 g/cm3 to about 0.5 g/cm3;
• wherein the aerogel powder has an average particle size less than or equal to about 500 μm;
• wherein the pre-heat treatment temperature ranges from about 300° C. to about 600° C.;
• and
• wherein the pre-heat treatment time is about 30 minutes to about 5 hours.

A method of treating an aerogel powder, the method comprising:

• heat treating an aerogel powder,
• wherein the heat treatment temperature ranges from about 300° C. to about 600° C.;
• and
• wherein the heat treatment time is about 30 minutes to about 5 hours.
