将三维网络结构的碳毡引入电磁屏蔽材料的应用，对其特有的电磁性能及网络结构作了分析，并进行了复合材料屏蔽效果计算和修正。研究表明：利用碳毡的孔洞结构和尺寸，辅之以金属镀层，能在较宽的频率范围内对电磁波有良好的屏蔽效率，且不需要很大的填充量。
The three-dimensional network structure of carbon felt into the application of electromagnetic shielding materials, its unique electromagnetic properties and network structure were analyzed, and the composite material shielding effect was calculated and corrected. The research shows that using the structure and size of the holes in the carbon felt together with the metal coating can provide good shielding efficiency to the electromagnetic wave over a wide range of frequency and does not require a large amount of filling.
