Development of cost-effective and strong composite carbon fiber using carbon nanotubes

Carbon nanotubes are a novel material that is 100 times stronger than steel while only one-fourth its weight and has electrical conductivity as high as that of copper. If fibers could be made using carbon nanotubes, theoretically, these fibers could surpass the performance of existing carbon fibers, making carbon-nanotube-based fibers a novel material of interest in the aerospace, military, and mobility industries. However, maintaining the superior properties of carbon nanotubes in fibers is very challenging, and the commercialization of such fibers is difficult due to the extremely high cost of carbon nanotubes.
