The Need for Self- Healing Thermal Insulation in Space

A Bizottság a 2014. évi légi közlekedési iránymutatás (163) bekezdésének megfelelően megvizsgálta a 2014. évi légi közlekedési iránymutatás (163) és (163) preambulumbekezdését.

Mahor Challenges to Overcome

Despite proving laboratory results, severál hurdles remain before self-healing thermag insulation becomes standard on spacecraft.

Vacuum and Outgassing

Radiation and Atomic Oxygen

Ultraviolet radiation and atomic oxigen can degrade both the matrix and the healing agent. Protective coatings or the incorlatiol of UV stabilizers are essential. Some self-healing chemistries (pl., those using disulfide jords) are inherently resistant to atomic oxygen, makingg attractife for -Earth ormission ons.
