摘要

This study focuses on the electromagnetic interference shielding effectiveness (EMI SE) of SiC nanowire/SiC ceramic composites (SiCnw/SiC) manufactured by chemical vapor infiltration of SiCnw aerogels with carbon-rich SiC. The total EMI SE of a 1.0 mm thick ceramic composite specimen with density of only 2.68 g/cm3, was found to be 43-44 dB, which indicates an excellent EM shielding capability of the ceramic composite corresponding to blocking of 99.99% of the incident EM signal. It was found that the carbon-rich CVI-SiC matrix possess excellent EM shielding properties, therefore, the CVI-SiC CMCs themselves possess an excellent EM shielding property as a result of the carbon-rich SiC matrix.
