Effectiveness of Low Frequency Electromagnetic Shielding of Concrete with the Functionally Primitives Materials of Short Carbon Fibers and Graphite

Article Preview

Abstract:

The electromagnetic shielding properties of short carbon fibers and graphite concrete were investigated, and the influence of the contents of the short carbon fibers and graphite on the electromagnetic shielding effectiveness of the concrete in low frequency was studied. The mechanism causing the influence of the short carbon fibers adulteration on the electromagnetic shielding effectiveness of the graphite concrete at low frequency was investigated. The maximum electromagnetic shielding effectiveness was up to 8.5dB in the low frequency range of 1MHz～1.8GH. The results of the investigation provide the basis for further designing and producing of high-powered electromagnetic shielding concrete at low frequency.
