At 13:34 on September 17, 2021, China's Shenzhou 12 manned spacecraft's return module successfully landed at the Dongfeng landing site.
High-performance heat-resistant materials: provide reliable protection for the return cabin
The return module of the Shenzhou 12 manned spacecraft carried three astronauts back to Earth. During the return process, although the return module and the atmosphere formed a big fireball, the astronauts inside would not be exposed to high temperatures. bake. How did the return cabin withstand the high temperature test of more than 2,000 degrees Celsius? This depends on an insulating material on its surface.
HTKJ Thermal Insulation Material Technology Corporation provides a high-performance honeycomb reinforced low-density heat-resistant material for the protective layer of China's return cabin. When the return capsule enters the atmosphere at high speed, the return capsule will violently rub against the atmosphere, and the surface temperature can reach more than 2,000 degrees Celsius. After our material, the reentry process will ablate and prevent heat for about 560 seconds, take away the heat, and then inside The temperature in the surface cabin can be maintained at more than 30 degrees Celsius.
