摘 要：In this study,we synthesized high-performance Carbon Fiber/Gold/Copper（CF/Au/Cu） composite wires by using a 2-step deposition method via sputtering and electrodeposition.After Au was sputtered on PANbased CFs as a pre-treatment,the wettability and surface reactivity of the CFs were improved,resulting in a homogeneous deposition of Cu on their surface.At different Cu electrodeposition time,the resulting CF/Au/Cu composite wires could possess a high strength of up to 3.27 GPa（～10 times stronger than copper wires） while their electrical conductivity could be as high as 4.4 × 105 S/cm（～75% of that for copper）.More importantly,since the composite wires were lightweight（up to 70% lower than Cu mass density）,they are a promising candidate to substitute conventional heavy metal wires in the future electrical applications.
