A measurement of the nonlinear thermomechanical characteristic and a development of a mathematical model for an ultra-lightweight carbon fiber reinforced plastic

隼鸟号小行星探测器和USERS空间系统的几个大气层再入舱隔热材料的比重高达1.5，占整个系统质量的很大一部分。本研究制备了一种超轻碳纤维增强复合材料LATS，获得了LATS在几种高温环境下的非线性热机械性能。即使对于恶劣的大气层再入环境，LATS作为热屏蔽材料的功能也得到了证明。为使该模型能应用于航天工业、铁路工业等领域，建立了相应的数学模型。

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.
