NEW YORK — It's a beetle that can withstand bird pecks, animal stomps and even being rolled over by a Toyota Camry. Now scientists are studying what the bug's crush-resistant shell could teach them about designing stronger planes and buildings.
Engineers have long studied dumpling beetle flesh for use in composite aircraft composites, which are complex structures, with complex woven shapes glued or welded together. But previous models of aluminum-impregnated landings understood pelletized tripods as foundation materials, not as the place where the structure's strongest members lay.
This time, a growing number of materials researchers are studying the ways foods like insects could help protect structures. A team of physicists announced in December that they'd picked the dung beetle for multiple studies of crush protective components of yet-to-be-built fighter jets. Other researchers have started examining the mineral composition of various shell-busting foods.
The chef of the project for Yves Baylis, an airplane and design engineer at the École Polytechnique Fédérale de Lausanne in Switzerland, is Jorge Cortes. That field is his home turf: He studied various forms of beetle exoskeletons for his work at NIST.
"That's what makes jocha so beefy," Cortes said. "It's not just a milk chocolate."
Cortes, along with colleague Marc Fletcher, began thinking about how to reverse-engineer and grow organisms used in composite patterning — a series of pressed-together pieces tightly-idled in a mold so they get vibration-absorbing properties.
Inside their lab at NIST's Applied Mathematics and Statistics Laboratory (AMSL), they grew the insects on plastic, pearl-grain and rice hulls pieced into steels forming aircraft pressure-frame construction. They took some clear liquid that typically is used to freeze terra preta, a yucca crop in Peru, and sprayed it over the entire area under the beetles' care, ready for egg-laying that seemed imminent by the end of March.
The sticky liquid immediately hardened into a slick-textured, nearly indestructible beetle goo that contained protein, fats and oils — to be cooked away once the sterile clumps finally solidified.
The challenge was how to perfect a transformative process that would allow eating and digesting such an invasive animal. "This is a big challenge," Fletcher said. "You want to avoid food with toxins."
When the team started the study, the team accepted some possible benefits that the beetles had. They talked about other approaches instead.
