Researchers at the Hong Kong University of Science and Technology (HKUST) have developed a new technology that can greatly enhance the ballistic-proof strength of ultra high molecular weightlinks polyethylene (UHMWPE) fiber by adding carbon nanotubes, says a HKUST press release:

Carbon nanotubes can improve the engineering properties of plastic fibers in ballistic-resistant garments enabling the garments to withstand forces with very high impact yet remain light. In addition, the high ventilating capability of carbon nanotubes means end products can be made more comfortable for users.

"The technology we have developed can effectively align nanotubes along the length of polymer fibers so the tensile strength of nanocomposite fiber becomes up to eight times stronger than steel," said Dr Ping Gao, Associate Professor of Chemical Engineering. (photo HKUST)
