Abstract: Based on the fiber nickel-plating coating process, the conductive carbon fiber can be made. The nickel-plating surface microstructure of the carbon fiber was observed by SEM. The hybrid fiber was made of the carbon fiber and the nickel-coated carbon fiber by the autoclave equipment. By electro-magnetic shielding effectiveness test (100 kHz - 18 GHz) and environment adaptability test, the results showed that electro-magnetic shielding effectiveness and anti-adverse environmental adaptability of the hybrid fiber composites were better than normal carbon fiber composites.
