In this study, an electroless method was used to obtain good electromagnetic interference shielding efficiency (EMI-SE) of Nickel-cobalt (Ni-Co) plated carbon fibers (CFs)/epoxy composites. The surface properties of the Ni-Co plated CFs were characterized by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD). The room temperature volume resistivity of the composites was measured using a four-point probe electric resistivity tester. The EMI-SE of the Ni-Co plated CFs/epoxy was tested by a EMI shielding analyzer. As a result, the electroless Ni-Co plated CFs/epoxy composite shows good electrical conductivity and shows the effect of good electromagnetic shielding. The Ni-CFs can lead to EMI-SE improvement due to the EMI absorption behavior of the Ni particles.
