    • Abstract

       

      Ni–Fe alloy coatings were successfully prepared on carbon fibre (CF) surfaces bymeans of electroplating at 25°C for 560 s. The structures and morphologies of the composite were characterized using X-ray diffraction and scanning electron microscopy. The coercivity (𝐻𝑐) and saturation magnetization (𝐻𝑠) of the Fe0.45Ni0.55/CF composites were 45.19 Oe and 1513.59 emu g−1, respectively. The reflectivity of Fe0.45Ni0.55/CF composites was less than −5 dB over the range of 1.1–5.4 GHz. The reflectivity of Fe0.45Ni0.55/CF composites was less than −10 dB over the range of 1.6–2.1 GHz. The lowest reflectivity of the Fe0.45Ni0.55/CF composites was −14.7 dB at 2.0 GHz and the corresponding thickness was 3.3 mm.
