Spider Silk-Spinning Technique Key to Stronger Fibers | LiveScience
Nanotubes are tightly packed in the new carbon nanotube fibers produced by Rice University and Teijin Aramid. This cross section of a test fiber, which was taken with a scanning electron microscope, shows only a few open gaps inside the fiber.

Mimicking silk-spinning spiders, scientists have created a type of nanotube fiber with an unmatched combination of strength, conductivity and flexibility.
These light, versatile fibers could find uses in the aerospace, automotive, medical industries, as well as the smart-clothing markets, researchers say.
Carbon nanotubes arehollow tubes of pure carbon just nanometers or billionths of a meter in diameter. Although they are only about the width of a strand of DNA, they are about 100 times stronger than steel and only one-sixth as heavy, and their conductive properties for both electricity and heat rival the best metal conductors ―enthralling qualities that have attracted much interest from researchers since they were [...]
