| titleOfInvention | A kind of carbon nanotube-carbon fiber multi-scale reinforcement and its preparation method and application |
| abstract | The invention discloses a process scheme for growing carbon nanotubes on the surface of continuous carbon fiber tows by catalytic chemical vapor deposition using a multi-component catalytic system containing copper components. The implementation method of the present invention includes the following steps: taking copper nitrate and ferric nitrate as necessary options, cobalt nitrate and nickel nitrate as optional options, configuring a catalyst precursor solution with anhydrous ethanol as a solvent, and then feeding the surface-activated carbon fibers into the solution dipping in an oven for 10-15 min and then drying in an oven; sending the carbon fiber bundles with catalyst precursors on the surface into a tube furnace, and performing catalyst reduction and CCVD growth of carbon nanotubes, respectively, to obtain carbon nanotube-carbon fiber multi-component Scale Enhancer. The invention can obtain the carbon nanotube-carbon fiber multi-scale reinforcement with more uniform distribution of carbon nanotubes and more regular arrangement of carbon atoms, and can significantly improve the interface bonding ability of the carbon fiber composite material. |
