Research is also advancing in aeronautics. A material that has been known for a long time has been studied for its many properties applicable to the sector … It is graphene.
By creating a graphene oxide airgel, English scientists have found a very effective sound insulator. This material offers many advantages, both ecological and sound. Its weight of 2 kilos per cubic meter, being much lower than the insulation usually used in aeronautics, planes, less heavy, would use less kerosene. Its ability to trap noise in the airgel cells allows the noise emitted by motors to be reduced by 16 decibels, bringing them to the same number of decibels emitted by a hair dryer … But it will be necessary to wait for the graphene oxide airgel is widely used in aeronautics. Its cost is too high because its production is not yet sufficiently deployed.
