Rewriting the history of K-carbon fiber manufacturing with carbon nanotubes

A space elevator, a structure connecting the Earth’s surface to a space station, would allow for the cost-efficient transport of people and materials. However, a very light yet strong material is essential to making such a technology a reality. The carbon nanotube is a new kind of material that is 100 times stronger than steel, yet four times lighter, with copper-like high electrical conductivity and diamond-like thermal conductivity. However, previous carbon nanotube fibers were not ideal for extensive use, owing to the small contact area with adjacent carbon nanotubes and limited length they possessed.
