Abstract: In order to improve the process of nickel-plated carbon fiber production efficiency as well as filled composite electromagnetic shielding materials development, nickel-coated carbon fiber (NiCF) was prepared by continuous plating process, and used for the preparation of NiCF reinforced acrylonitrilebutadienestyrene (ABS) composites (NiCF/ABS). Mechanical properties, electromagnetic shielding performance and their controlling factors of the composites were investigated. The results reveal that coupling treatment can improve the mechanical properties of the composite. Tensile strength and bending strength of composites have reached 41 MPa and 61.4 MPa respectively. The composites achieve excellent electromagnetic shielding effectiveness with a carbon fiber mass fraction (W_f) of 12%.
