Abstract
A graphite fiber is electroplated by passing the fiber continuously through an electrolyte solution in a tank. Current is delivered to the fiber at a contact immediately prior to the surface of the electrolyte in the tank. The voltage is maintained above 16 volts. The fiber is kept cool enough outside the bath to prevent degradation by recycling the electrolyte to bathe the fiber from the point of contact to the point of immersion into the electrolyte.
Claims21
A process for electroplating graphite fiber comprising:
- (a) passing the fiber continuously through an electrolyte solution in a tank in which a metal anode is immersed;
- (b) passing D.C. current through the fiber to the anode by delivering said current to the fiber at a contact immediately prior to the surface of the electrolyte in the tank;
- (c) maintaining the voltage across the electrolyte from the fiber to the anode above 16 volts;
- and
- (d) maintaining the fiber cool enough outside the bath to prevent degradation by recycling the electrolyte to bathe the fiber from the point of contact to the point of immersion into the electrolyte bath whereby metal from the anode migrates to the fiber and is bonded thereto.
