New Techniques Stretch Carbon Nanotubes, Make Stronger Composites

Researchers from North Carolina State University have developed new techniques for stretching carbon nanotubes (CNT) and using them to create carbon composites that can be used as stronger, lighter materials in everything from airplanes to bicycles.

By stretching the CNT material before incorporating it into a composite for use in finished products, the researchers straighten the CNTs in the material, which significantly improves its tensile strength -- and enhances the stiffness of the composite material and its electrical and thermal conductivity.
