【 摘 要 】

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 (𝐻_�?) and saturation magnetization (𝐻_�?) of the Fe_0.45Ni_0.55/CF composites were 45.19 Oe and 1513.59 emu g^�?1, respectively. The reflectivity of Fe_0.45Ni_0.55/CF composites was less than �?5 dB over the range of 1.1�??5.4 GHz. The reflectivity of Fe_0.45Ni_0.55/CF composites was less than �?10 dB over the range of 1.6�??2.1 GHz. The lowest reflectivity of the Fe_0.45Ni_0.55/CF composites was �?14.7 dB at 2.0 GHz and the corresponding thickness was 3.3 mm.
