Carbon nanowires were spun from carbon nanotube arrays. Their mechanical and electrical properties were also studied. The experimental data obtained after processing: the resistivity of carbon nanowires decreases with decreasing yarn diameter, the specific strength decreases with increasing helix angle of carbon nanowires, the average yarn strength increases with the height of the carbon nanotube array Increasing; carbon nanowires have very good consistency along the length. Tests on the combination of heating and tension spinning (HTS) show that the mechanical and electrical properties of carbon nanowires can be effectively improved by tensioning and heating the carbon nanotube bundles. The research on its application in the deep layer of smart composite materials Based, but also for its advanced intelligent composite materials research and development and application of technical basis.
