It seems that researchers in central China, studying hypersonic heat transfer, a subdivision of aerodynamics that studies gas motion laws, have developed a non-carbon-based heat-resistance material for hypersonic flight, according to the Global Times..."

China Develops Groundbreaking Heat-Resistant Material For Hypersonic Weapon
"At Mach 5 (3,836 mph), a hypersonic vehicle enters a dense atmospheric layer, the ambient gas undergoes not only density change, but also a significant temperature increase. This physical-chemical reaction is associated with the flight speed is converted into heat and chemical energy, which is a considerable heat barrier that had researchers around the world scrambling for new materials that could withstand temperatures far higher than the melting point of metal.
