금속메쉬, 알루미늄필름/섬유강화 복합재료의 전자파 차폐 효과에 관한 연구 = A Study on Electromagnetic Interference Shielding Effectiveness of Cu mesh, AI film / Fiber Reinforced Composites

다국어 초록 (Multilingual Abstract)

In this study, electromagnetic interference(EMI) shielding effectiveness(SE) of fiber reinforced composites(FRC) filled with aluminum(Al) film, copper(Cu) meshes and carbon black as hybrid conductive filler have been studied. Al film and Cu meshes are incorporated as conductive fillers to provide the electromagnetic shielding property of the FRC. The coaxial transmission line method of ASTM D4935-89 was used to measure the EMI shielding effectiveness of composites in frequency range 300 MHz to 1.5 GHz. The variations of SE of FRC with Ai film, fine Cu and general Cu meshes are described. The result indicate that the fiber reinforced Cu meshes are described. The result indicate that the fiber reinforced composites using Al film tiller was shown th exhibit up to 55-75 of SE.
