When we can get nanotubes, we will have the ultimate
reinforcing fiber. Really good graphite fiber has a modulus
(stiffness) of about 400 Mega Pascals with an elastic strain
to failure (stretch) of about 1%. Nanotubes are expected to
have a modulus of around 1.4 Tera Pascals and 15% elastic
strain to failure. We'll be making incredibly tough, stiff
4 meter planes that weigh less than 30 oz.
