В Китае работают над стелс-технологиями для космоса. Существует много идей: от покраски спутников в черный
It is noted that technologies are not suitable here,which are used for flights above the Earth, for example, for stealth aircraft. Also, a number of coatings cannot withstand vacuum, cosmic rays and sudden temperature changes.
In the new work, scientists created onbased on composite materials including paper and plastic, a multilayer honeycomb structure capable of absorbing up to 80% of radar radiation in the entire frequency range used today.
The weight of the coating has been reduced to 6 kg per 1 m2, which is significantly less than that of the existing modern materials for radar invisibility.
They also created transparent radar stealth coating for solar panels with a thickness of only 3 mm, but it remains resistant to bending and withstands impacts.
The researchers plan to continue working in this direction.
