TB 26-04 Webbings for Use in Elevated Oxygen Environments
NASA tested commercial webbings for elevated oxygen environments intended for future lunar and Martian missions. A natural-colored Kevlar/PBI webbing from Sturges Manufacturing Company, Inc. passed flammability testing at 37% oxygen.
Why it matters
Enriched oxygen environments reduce the prebreathe time required before extravehicular activities. Fire-resistant materials are essential for crew safety because these environments increase flammability risks.
The details
- Standard meta-aramid or nylon webbings fail flammability requirements in elevated oxygen.
- The natural Kevlar/PBI webbing demonstrated a maximum oxygen concentration of 37%.
- Final product performance must be validated in full configuration before use.
