Abstract
The electromagnetic shielding effectiveness of C-SiC/epoxy composites was investigated and compared with that of carbon fiber/epoxy composites. C-SiCs, short fibers with carbon cores and silicon carbide shells, were fabricated by a carbothermal reduction process using chopped carbon fibers (CFs) and rice husk ash. After presenting the morphology and structure of the C-SiC fibers, the electromagnetic interference shielding effect of SiC coated carbon short fibers is discussed. The Kα-band (26.5-40.0 GHz) shielding studies revealed that the maximum total shielding effectiveness (SET) of the composite with 25 vol% of C-SiCs is 17.07 dB, dominated by absorption, while the composite with 25 vol% of the same sized carbon fibers has a SET of 8.44 dB only.
