Flexible Composites for Space

Payload mass reduction and packaging efficiency in launch vehicles are essential for deep space exploration.  Inflatable softgoods have been identified as attractive approaches to meet these needs.  Applications include crew habitation and collapsible airlocks (in-space and on planetary surfaces), and inflatable decelerators for planetary entry systems.  However, heritage softgoods approaches are based on woven, crimped fabric.  The new idea is to replace woven fabric softgoods with flexible composites made from non-carbon fibers and flexible matrix resins that were originally developed for racing sailboats.  This new approach will decrease the engineering development time and cost, and also enable mass reductions from the heritage approach.

A number of flexible composite layups were considered, fabricated, and tested under static tension to evaluate stiffness, stress-strain behavior, failure loads, and failure characteristics.  Results will be published and comparisons will be made to a woven structure approach for a space habitat in a planned NASA TM.

Utilizes SOA composite fabrication techniques, provide a more consistent and predictable structural response compared to woven structures, lower required factors of safety and lower mass, better integration to standard composite structures

This is early/mid-stage (TRL 2) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
