NASA computer modeling analysis has shown that composites using carbon nanotube reinforcements could lead to a 30 percent reduction in the total mass of a launch vehicle.

"No single technology would have that much of an impact to reduce the mass of a launch vehicle by that much," explains Michael Meador, Program Element Manager for Lightweight Materials and Manufacturing at NASA's Glenn Research Center in Cleveland, Ohio.

Tensile properties of a carbon nanotube fiber-based composite tank were tested in a May 16 test flight.

NASA collaborated with Nanocomp in Merrimack, New Hampshire to make nanotube yarns and sheets, with the space agency developing specialized processing methods to fabricate COPVs.
