摘要

本研究將聚酯纖維熱定型為螺旋狀，將螺旋狀聚酯纖維進行化學鍍，後將其浸入不飽和樹脂中硬化定型並製成板材，使之成為具有導電性之複合薄膜材料。藉由螺旋纖維在基材內部進行導電通路，和伴隨產生之電磁感應，而使吸收材具有屏蔽電磁波之效果。無電極鍍鎳溫度為80℃電鍍40分鐘最為均勻，且經實驗發現，螺旋狀板材匹配直線板材後電磁波吸收效益遠比單層螺旋狀板材電磁波吸收效益優異。當固定螺旋螺距為0.5cm螺旋長度為3.5cm匹配5g直線時，電磁波吸收效果最高可達38dB。

This research transfers polyester fiber into spiral structure by thermosetting and makes the sprial fiber plated nickel by electorless method. After the process, we put the spiral yarn with nickel into the unsaturated resin to make the composite panel have electric conductivity. We expect that the compsite with spial yarn form the conductive interconnect and with the electromagnetic induction to absorb the electromagnetic wave. From the reseach, at 80℃ and 40 minutes of the electroless nickel plated process, the spiral yarn have the best cover with nickel. And we also find that the absorbent electromagnet effectiveness wave of the single composites with spiral yarn is less than spiral yarn composites covered by the straight copper composites. When the distant of spiral yarn is 0.5cm, the length is 3.5cm to match 5g straight copper wire, the best absorption of electromagnetic wave can reach 38dB.
