Composite carbon-plastic thread

Composite carbon-plastic yarn based on carbon nanotubes is a light, high-strength yarn with a lower degree of wear and high thermal conductivity (about 15 W/m×K)*. The use of such carbon-plastic threads can be used for production of prepregs, fabrics, and cables (including fireproof and electrically conductive), and production of high-pressure composite cylinders. For example, for storage and transportation of compressed gases of air, oxygen, nitrogen, acetylene and other gases, cylinders are used at a pressure of 16–20 MPa, which are made of seamless tubes. Modern high-pressure composite cylinders have an external power shell made of carbon fiber that is wound on the surface of the shell and impregnated with a binder material. External power shell of high-pressure composite cylinders can be reinforced with carbon nanotubes, which will make the cylinder walls extremely elastic and more durable.
