Self-healing material could plug holes in space ships

self-healing-material-space-ships2x.jpg

As the movies have shown us, space travel is an intimidating prospect, what with the possibilities of running out of air, the rocket engines conking out, or the shipboard computer deciding to bump off the crew. Another danger is fast-flying orbital debris piercing the hull. Scientists may be on their way to a solution to that one, however, in the form of a new self-healing material.

Developed by a team from the University of Michigan and NASA, the material is made up of thiol-ene-trialkylborane liquid resin, sandwiched between two polymer panels. As long as the resin is contained in the airtight space between the panels, it stays in its liquid form.

When either of the panels are pierced by a projectile, however, the resin leaks out of the hole and polymerizes upon contact with the oxygen in the air. As a result, it instantly forms a solid airtight plug in the hole.
