Hasta La Ideas

We’ve looked at carbon fiber in 3D-printed bikes, in furniture design, and coming out of Lexus’ crazy 360-degree loom. The stuff has long been vaunted for its high strength-to-weight ratio. And now, for the first time in decades, carbon fiber could experience a big change, thanks to one of the more popular breakthroughs in material science, graphene.

We’ve looked at graphene’s application in battery-ending supercapacitors before, but for those who don’t remember: Graphene is a one-atom thick layer of graphite (carbon) that is strong, and very, very light. And the tricky thing about graphene is making it, since it is so thin.

Recently, scientists at Rice University have managed to weave flakes of graphene oxide into carbon fiber. The result is something that surprised even the scientists who created it. The new fiber is considered to be extraordinarily strong, because knots created using the material are unusually strong.

We might think of knots as a handy way to tie something up. But in materials science they are way of measuring strength. Typically most fibers snap under the tension created at a knot. But with this new carbon fiber the strength at the knot is as strong as anywhere else along the thread of fiber.
