| Abstract: | Carbon fiber felt (CFF) with three dimensional structure is applied to manufacture electromagnetic wave shielding (EMS) composite materials .The composite's electromagnetic performance and its network structure are systematically analyzed.At the same time,shielding efficiency is calculated theoretically.The results show that with low loading level the metal coated CFF provides excellent EMS property in a wide frequency range due to its cavity structure and metallic coating. |
