Pennsylvania engineers stack Mylar sheets to create durable lunar habitat insulation
University of Pennsylvania researchers developed a new method to stack household Mylar film into a strong thermal insulator for future moon bases.
Extreme temperature resistance needed
Lunar environments experience temperature swings from hundreds of degrees below zero to boiling heat. Effective insulation is essential for any long-term human presence on the moon. Many standard materials cannot survive the bumps and compression required for lunar infrastructure.
Hybrid layered film stacks
The team created hybrid layered insulating film stacks by joining hundreds of Mylar sheets together. This assembly method combines strong thermal insulation with mechanical durability in a single product. The resulting stacks can bend and withstand substantial compression while maintaining their performance.
Packaging and transport benefits
These flexible insulators allow the material to be packed tightly for transport to space. Engineers say the design could survive rough treatment over many years of use. The research was published in ACS Applied Materials & Interfaces.
