Researchers develop thin heat shield for superfast aircraft

Phys.org  November 13, 2019
Existing heat shields are often very thick compared to the base they protect. Researchers at Florida State University designed a carbon nanotube/phenolic thermal protection layer (TPL) with heat shield functionality while maintaining designed mechanical strength compared to traditional carbon fiber reinforced polymers (CFRP) composites. These TPLs were integrated onto the surface of carbon fiber/bismaleimide composites to act as a heat shield for hybrid composites. The TPLs resulted in a 17% decrease of the through-thickness thermal conductivity for hybrid composites. The material retained its flexibility and strength after flame torch test It has the potential to protect the body of a rocket or jet from the intense heat it faces while flying…read more.
