METHOD OF PREPARING NICKEL-PLATED CARBON FIBER BY ELECTROPLATING

摘要

PURPOSE: A method of preparing nickel-plated carbon fiber by electroplating is provided to make the carbon fiber exert higher surface energy, and when added to a resin matrix, be well adhered to the matrix with improved interlaminar shear strength, impact strength and ductility. CONSTITUTION: In a method of preparing nickel-plated carbon fiber, carbon fiber is disposed between nickel anode and cathode bar in a nickel plating electrolytic solution, and current is applied to between the nickel anode and the cathode bar. The nickel plating electrolytic solution contains 30-210g/l of NiSO4, 30-100g/l of NiCl2, and 30-40g/l of H3BO3. The current application is made at current density of 5-80A/m2 for 10-60 seconds.
