Russian physicists "sewed" ultra-strong space material from nanotubes

Another unique design can be labeled “Made in Russia”. This time we are talking about a material developed by scientists of the famous Moscow Phystech on the basis of "cross-linked" multilayer carbon tubes, capable of withstanding ultra-high loads.

Carbon nanotubes are a relatively "young" invention, which is 25 years old. Since then, they have rightfully earned a reputation as a promising material with excellent strength and other unique physical characteristics. The main problem was that, due to the small size and structural features of the nanotube, it was not possible to weave it into solid fibers.

Phystech specialists in the course of experiments, having subjected nanotubes to ultrahigh pressures, successfully solved this problem by creating the necessary computer model in combination with practical experiments.

A unique, previously unknown property of nanotubes is to weld together upon contact at the moment of compression and restore their previous shape at normal pressure. As a result, super-strong materials are formed, surpassing in strength everything that is now used in aviation and astronautics.

As it turned out, previously considered unpromising multilayer pipes calmly withstand compression, a thousand times greater than the pressure at the deepest point of the World Ocean, in the Mariana Trench, the depth of which exceeds 11 km.
