SURFACE-TREATMENT OF CARBON FIBER

摘要

T10-25186C/KS/81 method for producing carbon fibers exhibiting excellent adhesive properties to resins and having high strength and heat-oxidation resistance, comprising electrically treating high strength carbon fiber in an aqueous solution of a sulfuric acid salt under conditions such that the current density is from about 0.05 to 0.5 A/m2 and the product of current density, voltage, and processing time is from about 0.02 to 8 A-V-min/m2, while continuously moving the carbon fiber as an anode in the aqueous solution.
