Manufacturing method for braided carbon fiber bundles via physical vapor deposition

Manufacturing method for braided carbon fiber bundles with enhanced conductivity via physical vapor deposition metal coating

This technology relates to a method for manufacturing carbon fiber bundles for braiding using physical vapor deposition (PVD). Specifically, it provides a method for producing metal-coated carbon fiber bundles that exhibit excellent electrical conductivity and are suitable for braiding using conventional wire braiding machines. The method comprises: a) a spreading step of flattening the carbon fiber bundle; b) a coating step of applying a metal coating to the surface of the spread carbon fiber using PVD; and c) a sizing step of applying a sizing agent to the metal-coated carbon fiber while it is formed into a bundle.

Existing solutions in this field have faced structural and functional limitations that required improvement.

This technology provides a method for manufacturing braided carbon fiber bundles via PVD, which can be applied to relevant industries to enhance performance and efficiency.
