中文摘要:
      针对FeCuNbSiB非晶带材与环氧树脂基体不浸润的难题,本文通过表面化学改性,在FeCuNbSiB非晶带材两面分别生成一层厚度5μm~10μm、相结构为Cu0.75Fe2.25O4和Fe3O4的界面层。界面层与带材结合强度高,与环氧树脂浸润性好;以FeCuNbSiB非晶带材为增强材料,同时按FSS网络设计的FeCuNbSiB非晶带材/环氧树脂铺层在13-18GHz频带出现R=-5dB~-10dB的吸收峰。增加铺层数,吸收峰值不变,但吸收峰频带往低频率方向移动。利用此特性可以修正其它复合材料的雷达波吸波特性,拓宽吸收频带,增加吸波性能。

英文摘要:
      In this paper, aiming at the problem of non-infiltration between FeCuNbSiB amorphous alloy strips and epoxy resin matrix, the interface layer of Cu0.75Fe2.25O4 and Fe3O4 phases, which the thickness was about 5μm~10μm, was successfully obtained on the both sides of FeCuNbSiB amorphous alloy strips by surface chemical modification. The interface layer has high bonding strength with FeCuNbSiB amorphous alloy strips, and good infiltration with epoxy resin matrix. The epoxy resin matrix composites using the amorphous alloy strips as reinforcing materials were prepared according to FSS grid design, the electromagnetic wave absorption peaks of composite board appeared in the frequency range of 13-18GHz and the value of reflectivity R was between -5dB and -10dB.The value of absorption peaks kept constant but absorption peak frequency bands shifted to lower frequency along with increasing the layer number of FeCuNbSiB strips. This kind of character can be used to modify radar absorbing properties of other composites and broaden absorption band.
