本研究以兩種不同電磁波吸收粉體,其活性碳粉與氧化鐵粉依照5種重量百分濃度10%、15%、20%、25%、30%分別加入到不飽和聚酯樹脂當中,並將蜂巢結構含浸至其中,待其硬化後,以網路分析儀測量蜂巢結構對電磁波的吸收效果。由本實驗得知,以添加活性碳粉的不飽和聚酯樹脂含浸之蜂巢結構對電磁波吸收效果優於添加氧化鐵粉,且隨著蜂巢結構的孔徑縮小厚度增加對電磁波的吸收效果上升,最佳的吸收材為添加重量百分濃度30%之活性碳粉,孔徑3mm,厚度10mm之蜂巢結構,吸收值達18.5dB。
The absorption of electromagnetic waves in two different active carbon powder and iron oxide powder according to the weight percent concentration of 5 10%, 15%, 20%, 25%, 30% were added to unsaturated polyester resin which will Impregnated honeycomb structure to which, until after hardening, to measure the cellular structure of the network analyzer on the electromagnetic wave absorption. By the experimental results, to add the activated carbon powder of unsaturated polyester resin impregnated honeycomb structure on the absorption of electromagnetic waves better than to add iron oxide powder, and with the honeycomb structure to increase the thickness of the pore narrowing effect on the absorption of electromagnetic waves rise, the best Absorbing material was added 30% of the active carbon, aperture 3mm, 10mm thickness of the honeycomb structure, the absorption values are 18.5dB.
