Now that carbon-fiber composites have migrated from the world of blank-check motorsports to semiaffordable production cars such as the BMW i3 and Chevrolet Corvette, whatâs next? Is there another breakthrough material that will reset our expectations for strength, stiffness, and weight the way carbon fiber has? Carbon nanotubes will. Imagine a tiny pipe with walls made of carbon atoms linked neatly together. The ânanoâ part of the name comes from nanometer, meaning one-billionth of a meter. Each carbon nanotube is only one nanometer in diameter, which is 2000 times smaller than a carbon-fiber filament. But more significant than size are the dramatic differences in crystal structure and physical properties between carbon nanotubes and carbon fiber.
