Strength per weight is simply a formula. You can see it as 600 times
lighter than steel on an equal strength basis, or as being 600 times
stronger than steel on an equal weight basis.

By comparison, Kevlar is 5 times stronger than steel on an equal weight
basis. Nanotube fabric can take more heat than Kevlar as well.

Laminate nanotube fabric with graphite epoxy and an almost 'magical'
hull material is born. This laminated fabric could be used throughout
the spaceplane to strengthen and lighten the spaceplane beyond any
other material known.
