Brazing of Aluminum alloys IN Space (BRAINS)
Brazing with a molten alloy is a possible solution for the repair of damaged space vehicles/habitats, and for construction in the microgravity of space or in human habitats (controlled atmosphere and/or vacuum). The flow of the brazing liquid on Earth is controlled by Earth’s gravity, but in space, gravity is negligible. Thus, when building structures in space, it’s important to understand how microgravity affects the ability to join materials.
This experiment is planned to launch aboard SpaceX-21 to the International Space Station (ISS) in December 2020.
The Brazing of Aluminum alloys IN Space (BRAINS) experiment will examine how to bond materials in space. When astronauts are living and working on long-duration missions, they will need to know how to effectively repair and join metal parts in the microgravity environment. It is critical that astronauts are able to create strong joints via a process known as brazing to ensure safe and lasting structures.
