A carbon fiber reinforced plastic (CFRP) has been widely used as a heat shield material in aerospace community. The CFRP is very trusted as the heat shield material for a re-entry vehicle but a fuselage becomes heavy because the CFRP is the high density material. Very recently, Okuyama developed a new ultra light-weight CFRP that is called LATS. In order to design the lightweight re-entry vehicle, this paper describes the thermal characteristics of the LATS in the high enthalpy flow. Furthermore, this paper described a comparison of the thermal characteristics of the LATS and the conventional high density CFRP. It found that the surface and in-depth temperatures of both resembled well as these experiment. The LATS can be applied to the heat shield material for the re-entry vehicle.
