Paraglider perspective shapes Boeing’s honeycomb core

Material to be used in airplane cabin components gives an engineer a firsthand connection to safety.

Boeing’s recent approval to use a newly qualified version of an aramid paper honeycomb core in airplane interiors is more than a materials win – it’s a victory for human ingenuity. For Eileen Kutscha, a materials and process engineer in Tukwila, Wash., who helped lead the effort, the project bridged two worlds she cares about deeply: the laboratory and the sky.

“This qualification effort spanned the whole spectrum of what I do,” Kutscha said. “From scouting new materials to screening candidates and writing the specification that others will use for years. It was rewarding technically, but it also meant something personal. I could see the link between the materials I certify and the people who rely on them.”

The journey to this breakthrough has been a long one. Kutscha has been working to find an alternate honeycomb core since 2020, but the effort to identify the right material goes back to 2015. The qualification is the culmination of the work of several people over a decade, reflecting their deep commitment to innovation and safety.

Soaring insights shape material choices

Kutscha’s connection to flight extends beyond her work on the honeycomb core. She’s an avid paraglider, with more than 200 flights and the Federal Aviation Administration’s (FAA) P3 certification to fly in challenging conditions. In fact, the strong, lightweight lines that attach to her paraglide’s wing are made from similar aramid fibers used in Boeing’s newest honeycomb core, giving her a direct, tangible connection between the gear she trusts in the air and the materials she qualifies in the lab.

  • Her paragliding experience shaped how she thought about qualifying a material that shows up across platforms, from airplane interiors, including aircraft stow bins, ceilings and sidewalls, to satellite structures and even rotorcraft components.

“Before learning to paraglide, I had no idea what flight felt like,” she said. “Very rarely do materials engineers get to be involved in wing design, where materials are stressed in flight. Being in the air made me realize how important it is that every material we put on an aircraft is high-quality and will help ensure safety. “Engineers typically aren’t the pilot, but when paragliding, I get to be the pilot. And that changes how I think about the final product.”

Back to basics

The new version of the honeycomb core brings practical advantages. The aramid fibers that make up the honeycomb core have flame resistant properties, helping to make them more suitable than many traditional materials for use on interiors applications where safety is critical.

“Honeycomb cores have to meet strict requirements for structural performance and flammability,” Kutscha explained. “We didn’t simply swap materials. We went back to basics — screening the core at its raw form, running mechanical tests like single-cantilever beam evaluations for crack propagation, and using advanced flammability tools such as microscale calorimetry so we could compare candidates side-by-side with existing materials.”

Disciplined decisions

That rigor reflects lessons Kutscha draws from paragliding: Evaluate conditions, make conservative decisions, and know when not to fly.

“Safety is critical in the air,” she said. “Before every flight, I assess cloud level and wind conditions. If something doesn’t feel right at launch, you don’t go. The same mindset applies to materials.

“What’s satisfying is knowing this isn’t just a one-off test,” Kutscha said. “We set a foundation so materials can be ready when new aircraft or new needs arise. It gives engineers and designers options, and that can help translate to safer, more efficient manufacturing.”

Material matters

For Kutscha, the project reinforced that materials aren’t abstract properties on a data sheet. They’re the fibers that help keep people safe, whether strung into a paraglide line or formed into a honeycomb core in an airplane panel. “Once I realized the lines on my wing were made from similar aramid fibers I test every day, I recognized that these are the materials people are trusting to keep them aloft.”

Her advice to engineers and hobbyists alike is rooted in the same discipline: Keep learning, stay curious, and respect safety. “If it were easy, I wouldn’t do paragliding,” she said, laughing. “You get better by enjoying the process, not just the destination. Material development takes time, but the payoff is helping to design a stronger, safer product that people can trust.”
