According to the adiabatic principle for insulation, a new high-temperature vacuum insulation panel (HT-VIP) is put forward, which can be used in high temperature environment. The material is consisted of the core material which is SiC foam ceramic and the flawless outer shell layer of carbon fiber reinforced composites by chemical vapor infiltration (CVI) and polymer infiltration and pyrolysis（PIP）. Moreover, the SiC film is coated by low pressure chemical vapor deposition (CVD) process to seal the surface, in the meantime the inside is a vacuum state. Therefore, the new ultra-temperature vacuum insulation composites with novel structure not only can be used at high temperature, but also have a very low coefficient of thermal conductivity compared with C/C and C/SiC composites. Material density is 0.81 g/cm3, and the compression strength is 8.75 MPa. The effective thermal conductivity of HT-VIP ranges from 0.2 W/(m·K) to 1.16 W/(m·K) in 373—1173 K temperature, lower than that of C/C and C/SiC composites by an order of magnitude.
