MIT engineers developed a nanostitching technique to make better and safer airplanes.
MIT engineers have just figured out how to make lighter and more durable composite materials that could impact the aerospace industry.
But composite materials present a challenge— they are almost like a sandwich of materials. There’s space between their layers. Engineers typically use a special kind of glue to fill these spaces. First, they grew a forest of nanotubes so small that tens of billions of these tubes can fill an area smaller than a fingernail. They used a process called “chemical vapor deposition,” which caused carbon to settle onto a surface as tiny, hair-like supports. Once those hairs were removed, these densely packed tubes of carbon remained. They acted like a bonding agent, or an ultrastrong Velcro, so it kept the layers tightly together.
