[0005] However, at present, there is no device that can test the anti-vibration performance of nano-heat-proof materials in an extreme high-temperature environment up to 1500°C.

In order to confirm the reliability of anti-heat insulation materials and structures of hypersonic vehicles in harsh high-temperature and strong-vibration composite environments, and ensure the safety of long-range flights, the research and development departments of hypersonic vehicles are currently working on nano-scale heat-resistant materials in thermal-vibration composite environments up to 1500°C. Therefore, the development of thermal-vibration combined experimental device for nano-insulation materials in extremely high-temperature environments not only has an important engineering application background, but also is a challenging research topic.
