Evaluation of Electromagnetic Pulse Shielding Performance of Amorphous Metallic Fiber Reinforced Cement Composite

비정질 강섬유 보강 시멘트 복합체의 전자파 차폐성능 평가

In this study, it evaluate the electromagnetic pulse shielding performance of amorphous metallic fiber reinforced cement composite with other steel fiber reinforced cement composite. Hooked-ended steel fiber, smooth steel fiber and amorphous metallic fiber were reinforced 2.0 vol.% in cement composites respectively. The electromagnetic pulse shielding performance was evaluated by MIL-STD-188-125-1. As a result, shielding performance of amorphous metallic fiber reinforced cement composite was higher than Hooked-ended and smooth steel fiber reinforced cement composites. In addition, the relationship between the electrical conductivity and the electromagnetic pulse shielding performance of the cement composite was confirmed.
