| Research Abstract |
Specific gravity of a heat shield material of several atmosphere reentry capsules which were used for the Hayabusa asteroid probe and the USERS space system is as large as 1.5, it accounted for much of the whole system mass. In this study, we made an ultra-lightweight CFRP which was named the LATS, acquired the nonlinear thermomechanical property of the LATS under several high-temperature environments. Even as for the severe atmosphere reentry environment, the LATS functioned as the heat shield material was shown. It be possible to utilize this LATS for the space industry and the railroad industry and so on, a mathematical model for these industries was developed.
