摘　　要：制备了铁基非晶粉体／S-玻璃纤维／环氧树脂复合材料板，采用波导法测定了复合材料的电磁参数。研究表明，复合材料板吸波机理主要以磁损耗为主，所制备的复合材料板中，当非晶粉体含量为66．7 wt％，厚度为5 mm时具有最佳的综合性能，密度为2．1g／cm3，抗拉强度为290 MPa，有效反射损耗（优于-10B）的频宽达到了2．2 GHz（15．8～18GHz）。Fe-based amorphous powders/S-glass fiber reinforced epoxy composite material panels were pre-pared based on previous procedure.In this study,the waveguide method was used to measure the electro-magnetic parameters of composite material panels.The results showed that amorphous powders were even-ly distributed between the layers of M-glass fibers.The main absorbing mechanism of composite material panels was the magnetic loss.For the sample with amorphous powder content of 66.7wt% and 5mm thick-ness present the best comprehensive properties,with a density of 2.1 g/cm3,tensile strength for 290 MPa, the effective bandwidth （better than -10 dB）achieved 2.2 GHz （15.8~18 GHz）.
