New materials to deflect massive amounts of surface heat don’t come from nature.
A protective coating of carbon nanotubes may help the Pentagon field warplanes and missiles that can survive the intense heat generated at five times the speed of sound.
Researchers from Florida State University’s High-Performance Materials Institute, with funding from the U.S. Air Force, discovered that soaking sheets of carbon nanotubes in phenol-based resin increases their ability to disperse heat by about one-sixth, allowing a thinner sheet to do the job.
