Description
The study presents a technology enabling the fabrication of ZrO₂–CNT composites for heat shield applications using the FAST/SPS method. As key components of vehicles traveling outside the Earth's atmosphere, heat shields require materials that meet strict performance criteria, particularly those related to thermal properties. The proposed methodology enabled the production of a monolithic heat shield demonstrator using FAST/SPS technology.
Zirconium dioxide (ZrO₂) exhibits properties that make it suitable for a wide range of applications, while carbon nanotubes (CNTs) show significantly higher electrical conductivity. Their combination in the 3YSZ-10MWCNT composite makes the material well suited for FAST/SPS processing. Additionally, a protective coating deposited by ACS (aerosol cold spraying) was applied to prevent CNT oxidation. The approach allows the fabrication of monolithic heat shield structures, but scaling is restricted by the maximum sample diameter feasible in current FAST/SPS systems.
