Going big: UD researchers report progress in development of carbon nanotube-based continuous fibers

Newark, DE | Posted on July 25th, 2012

According to Tsu-Wei Chou, Pierre S. du Pont Chair of Engineering, who co-authored the articles with colleagues Weibang Lu and Amanda Wu, there has been a concerted scientific effort over the last decade to "go big" - to translate the superb physical and mechanical properties of nanoscale carbon nanotubes to the macroscale.

The result, he says, has been the development of continuous fibers comprised solely of carbon nanotubes held together through local entanglements and van der Waals forces, a type of weak molecular interactions.

"Despite a discontinuous microstructure, these carbon nanotube fibers exhibit strengths comparable to current high performance fibers with significantly lower densities, creating new avenues for ultra-light weight multifunctional composite materials and structures," explains Chou.

"Furthermore, their flexibility and electrical conductivity have gained attention and given rise to the potential for carbon nanotube fibers to serve as embedded strain and damage sensors."

The challenge, however, remains how to scale up the material's size without sacrificing performance and functionality.

Lu's article, published in Advanced Materials, provides an in-depth analysis of the current carbon nanotube fiber processing methodology, including drawbacks and potential avenues for improvement. The article offers a thorough comparison of the current physical, electrical and mechanical properties of carbon nanotube fibers.

Wu's article, published in Materials Today, details the recent experimental characterization of carbon nanotube fibers performed by the Chou group. The review emphasizes the dynamic electromechanical behavior of carbon nanotube fibers and explores opportunities for carbon nanotube fibers in advanced composite applications.

About the researchers

Weibang Lu received his doctoral degree in solid mechanics from Tsinghua University, China, in 2009. His research focuses on the development of theoretical and computational approaches to analyze and predict the behavior of carbon nanotube fibers, with particular emphasis on atomic level approaches.

Amanda Wu received her doctoral degree in materials science and engineering from UD in 2009. Her work explores the experimental characterization of composite materials and their reinforcements with particular emphasis on the dynamic, high strain rate behavior of materials.

Lu and Wu are both research associates in the Department of Mechanical Engineering and the Center for Composite Materials.
