    摘要:

    針對FeCuNbSiB非晶帶材與環(huán)氧樹脂基體不浸潤的難題,本文通過表面化學(xué)改性,在FeCuNbSiB非晶帶材兩面分別生成一層厚度5μm~10μm、相結(jié)構(gòu)為Cu0.75Fe2.25O4和Fe3O4的界面層。界面層與帶材結(jié)合強度高,與環(huán)氧樹脂浸潤性好；以FeCuNbSiB非晶帶材為增強材料,同時按FSS網(wǎng)絡(luò)設(shè)計的FeCuNbSiB非晶帶材/環(huán)氧樹脂鋪層在13-18GHz頻帶出現(xiàn)R=-5dB~-10dB的吸收峰。增加鋪層數(shù),吸收峰值不變,但吸收峰頻帶往低頻率方向移動。利用此特性可以修正其它復(fù)合材料的雷達(dá)波吸波特性,拓寬吸收頻帶,增加吸波性能。

    Abstract:

    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.
