With the rapid development of new energy industry, a variety of clean energy is increasingly pouring into people's eyes. Fire insulation materials commonly used in our life are glass fiber cotton, aluminum silicate cotton, composite heat insulation board. However, traditional fire insulation materials have defects such as high thermal conductivity, large thickness, general fire and waterproof performance, and fast decay of heat preservation performance. Compared with traditional thermal insulation materials, aerogel composite materials only need 1/5-1/3 thickness to achieve the same thermal insulation effect by virtue of its structural characteristics, and excellent thermal insulation performance.

　　The application market of aerogel is very promising. Aerogel composites have excellent mechanical properties, good adiabatic coefficient and wear resistance, and can achieve weight reduction, energy saving, noise suppression and other functions. They are widely used in automotive, aerospace, household appliances, medical instruments and other fields, so they are widely welcomed by all walks of life.

　　At present, with the progress of science and technology, the scientific research of aerogel composite material is becoming more and more perfect, especially its application field has been greatly expanded, such as the shipbuilding industry began to use the material in the manufacture of Marine concrete, so as to achieve ship weight reduction, corrosion prevention, reduce friction resistance and other functions, saving a lot of energy; In nuclear power plants, aerogel composite materials are also widely used, thus realizing the pressure of cooling pump shell system and preventing nuclear radiation. The military field has also begun to use this material in a large number, realizing the lightweight of the armored vehicle body, reducing impact noise and other functions, so as to ensure the safety of troops, effective attack.

　　To sum up, aerogel composites have broad market prospects and will be widely used in automobile, aerospace, household appliances, medical instruments, shipbuilding and other industries, which will help to save energy and reduce emissions, form emerging industries, and improve economic and technological levels.
