This research investigated the metal-coating method of carbon fibers (CF). Nickel-coated carbon fibers (NiCF) were fabricated by electroless plating
and ABS composites filled with CF and NiCF were prepared by kneading method. The influence of CF and NiCF contents on the electrical conductivity and electromagnetic shielding effectiveness of ABS based composites was studied. The results indicated that an even and intact nickel coating could be plated on carbon fibers under a suiltable pretreatment and plating conditions
and the electrical resistivity of CF decreased 2 orders of magnitude when the plating time was 5min. The electrical resistivity of composites decreased with CF and NiCF content increasing. The corresponding electromagnetic shielding effectiveness of composites increased as filler content increasing
and the value reached 51 dB for the composite containing 25wt% (13.3vol%) NiCF.
