Aerogels as an innovative insulation material
Aerogels are highly porous solids that are produced in a so-called sol-gel process with subsequent drying under extreme conditions. This process produces materials with a porosity of more than 95 percent. This gives aerogels the following characteristics:
a very low density due to the extremely high air content
Good sound-absorbing properties
very low thermal conductivity
Due to these outstanding properties, aerogels offer potential applications in various industries, including the aerospace sector. They also represent a promising solution for specialized requirements in the field of insulation materials.
In addition, the acoustic properties of aerogels can be adapted to the respective framework conditions of the area of application, e.g. with regard to sound absorption in different frequency ranges. The material properties can be specifically varied by using different base materials or adapting the manufacturing process.
The data presented here was collected as part of a joint research project with the German Aerospace Center (DLR) and the University of Cologne.
