AboutAbout the lab
Taking on the limits of materials in extreme environments
The Arai Lab studies materials used in extreme environments such as atmospheric reentry and aerospace.
Its research is presented under the themes of "protecting from heat," "withstanding heat," "lightweight and high strength," and "digital twins."
Using the joint-use program for the arc-heated wind tunnel at JAXA's Institute of Space and Astronautical Science, the lab also conducts experiments that expose fabricated specimens to high-temperature, dynamic-pressure environments.
Lab visits are accepted at any time.
Key terms
- Arc-heated wind tunnel
- A facility at JAXA's Institute of Space and Astronautical Science that simulates planetary atmospheric entry environments. It is used for experiments that expose specimens to high-temperature, dynamic-pressure environments.
- Materials for atmospheric reentry
- Materials used to protect against heat during reentry into the atmosphere. They are presented on the lab's website as one of its research pillars.
ResearchResearch themes
The Arai Lab's stated aim is "to take on the limits of materials in extreme environments." Its research is presented in four pillars: materials for atmospheric reentry, heat-resistant materials for aerospace, structural materials for aerospace, and evaluation and analysis of mechanical properties.
