The development of flexible air/water vapor permeable composites designed for shielding the electromagnetic field has received an increasing amount of attention in recent years. A great deal of the attendant research has dealt with the development and investigation of electromagnetic shielding (SE) composites with textile-based reinforcements. However, little attention has been paid to the simple prediction of their SE ability, especially in terms of industrial applications. In this study, we investigated the design and properties of carbon-fiber reinforcements for use in epoxy composites that provide SE protection. Here, we selected the Aksaca electrically conductive continuous carbon-fiber roving and prepared different reinforcements with woven structures before investigating the effects of the weft and warp sett and the thickness of the warp and weft threads on the SE ability. To measure the shielding effectiveness, we used the coaxial transmission line method, while an analytical approach was adopted to predict the shielding effectiveness of the carbon reinforcements and to compare the calculated values with the experimental data. The SE effectiveness of the reinforcements varied from 10 to 45 dB at a frequency of 1.5 GHz, with good agreement between the calculated and experimental results.

近年来，用于屏蔽电磁场的柔性空气/水蒸气可渗透复合材料的开发受到越来越多的关注。大量随之而来的研究涉及具有织物增强材料的电磁屏蔽 (SE) 复合材料的开发和研究。然而，很少有人关注对其SE能力的简单预测，特别是在工业应用方面。在这项研究中，我们研究了用于提供 SE 保护的环氧复合材料的碳纤维增强材料的设计和性能。这里，我们选择了 Aksaca 导电连续碳纤维粗纱并制备了具有编织结构的不同增强材料，然后研究了纬线和经线设置以及经线和纬线的粗细对 SE 能力的影响。为了测量屏蔽效果，我们使用同轴传输线方法，同时采用分析方法来预测碳增强材料的屏蔽效果并将计算值与实验数据进行比较。在 1.5 GHz 的频率下，增强材料的 SE 有效性从 10 到 45 dB 不等，计算结果和实验结果之间具有良好的一致性。同时采用分析方法来预测碳增强材料的屏蔽效果并将计算值与实验数据进行比较。在 1.5 GHz 的频率下，增强材料的 SE 有效性从 10 到 45 dB 不等，计算结果和实验结果之间具有良好的一致性。同时采用分析方法来预测碳增强材料的屏蔽效果并将计算值与实验数据进行比较。在 1.5 GHz 的频率下，增强材料的 SE 有效性从 10 到 45 dB 不等，计算结果和实验结果之间具有良好的一致性。
