本研究以兩種不同導電性粉末，活性碳粉與氧化鐵粉加入不飽和聚酯樹脂當中，並將不同孔徑與厚度之蜂巢結構含浸至其中，待其硬化後對兩種不同材料的電磁波吸收效益進行比較，最後製成板材再分析對電磁波吸收值有何不同的效果。實驗研究得知，以活性碳粉含浸之蜂巢結構吸收效果最佳，且隨著活性碳粉添加重量百分濃度的增加和蜂巢結構孔徑縮小與厚度增加，其吸收效果也隨之上升。蜂巢結構孔徑3mm厚度10mm，以活性碳粉重量百分濃度30%之不飽和聚酯樹脂含浸對電磁波吸收效果有18.5dB，製成板材吸收值可達28.6dB。

In this study, two different conductive powder, iron powder, activated carbon powder and unsaturated polyester resin were added, and different pore size and thickness of the honeycomb structure impregnated to one, wait until after hardening of the electromagnetic wave absorption of two different materials Effectiveness of comparison, the final analysis made of sheet metal and then the differences between the electromagnetic wave absorption effect. Experimental study indicated that the impregnation of the honeycomb structure of active carbon powder absorbs the best, and with the added weight percentage of active carbon powder concentration and reduce the thickness of the honeycomb structure to increase its aperture effect of the absorption rise.
