Nanocomp Technologies has built a 3 foot by 6 foot sheet of woven and layered carbon nanotubes with a breaking strength stronger than stainless steel.

The sheets are also lightweight, with a density of 0.2-0.3 grams per cubic centimeter (30 times less dense than steel). The final material is paper-like and can be folded, stretched and cut with scissors.

The millimeters-long nanotubes are woven into 30nm diameter bundles, which in turn are layered on a rotating drum, where electrostatic forces hold the bundles together.
