文章摘要：為開發(fā)出綜合性能好的電磁屏蔽復(fù)合材料,首先分析了材料對電磁波的屏蔽機(jī)理,給出不同材料模型的屏蔽效能計算公式。進(jìn)而提出了＂樹脂＋鎳?yán)w維網(wǎng)＋樹脂＂的分層結(jié)構(gòu)屏蔽復(fù)合材料設(shè)計模型,估算了屏蔽網(wǎng)絡(luò)在高頻時因感抗電流所帶來的屏蔽效能。實(shí)驗(yàn)制備了復(fù)合材料的測試樣品,對其進(jìn)行屏蔽效能測試的結(jié)果表明：基于鎳?yán)w維網(wǎng)絡(luò)屏蔽的復(fù)合材料在14kHz～18GHz都具有較高的屏蔽效能,頻率為450MHz時達(dá)到72dB。設(shè)計的材料模型充分利用了材料結(jié)構(gòu)對電磁波的屏蔽機(jī)制,對高效屏蔽復(fù)合材料的設(shè)計具有理論價值和指導(dǎo)意義。

Abstr：To develop electromagnetic shielding composites having integrated properties, we analyzed the shielding mechanism of materials against electromagnetic wave, and put forward formulas of shielding effectiveness of different materials model. Moreover, we presented an optimized model of laminated structural shielding composites of resin-nickel fiber network-resin , estimated the shielding effectiveness from inductive current of the shielding network at high frequency, and manufactured and tested test samples of the proposed composites. The test results of shielding effectiveness show that the shielding composites based on nickel fiber network have a high shielding effectiveness in 14 kHz-18 GHz, reaching 72 dB at 450 MHz. The optimized model makes fully use of shielding mechanism of the materials against electromagnetic wave, thus it provides theoretical basis and guidance for the design of high efficiency shielding composites.
