In this work, the nickel electrolytic plating on carbon fibers was carried out to improve electric conductivity of the fibers, and the effects of nickel content and coating thickness on electric conductivity were studied. The surface properties of carbon fibers were characterized using X-ray diffraction (XRD) and scanning electron microscope (SEM). The electric conductivity of the fibers were measured using a 4-points testing method. As experimental results, it was observed that the electric conductivity was predominantly increased in the presence of metallic nickel particles on carbon fiber surfaces, and showed the highest value when nickel particles formed complete metallic layers. |
