Unique Micro Knot As Strong As Rest of Fiber
Whether you’re tying off your boat or making textiles, the weakest part of the rope or fiber is at the knot. The crushing, chaffing and shearing forces where the line comes together is the point most likely to fail along the entire length.
Not so with this micro-knot, which Rice University researchers made from carbon fiber created out of graphene oxide. Failure due to stress is as likely to occur at any other point along the fiber as at the knot. They say their discovery could lead to better materials made from carbon fiber, like aircraft parts, fabrics and composites.
“To see this is very strange,” said chemist James Tour, who headed the study published in the journal Advanced Materials. “The knot is as strong as any other part of the fiber. That never happens in a carbon fiber or polymer fibers.”
