영문 초록

Electromagnetic interference(EMI) shielding effectiveness of glass and carbon fiber reinforced composites with Ti. Ni. Mg powder were investigated. We fabricated glass and carbon fiber reinforced composites filled with metal powder and nano carbon black. The measurements of shielding effectiveness(SE) were carried out frequency range 300MHz – 1GHz for commercial purposes such as electric or telecommunication devices. The return loss and loss due to absorption were also measured as a function of frequency in the micro wave(300MHz‐1GHz) region. It is observed that the SE of the composites is the frequency dependent, increase with the increase in filler loading. The Mg metal powder filled composite show higher SE compared to that of carbon black. The Mg metal powder/epoxy composite were shown to exhibit up to 40dB of SE. The result indicate that the composite having higher filler loading can be used for the purpose of EMI shielding as well as for some microwave applications.
