Fiber-Reinforced Composite Material Bonded to the Metal Molding Material Impact on the Electromagnetic Shielding Effectiveness

This study investigated electromagnetic interference(EMI) shielding effectiveness(SE) of the copper mesh and aluminum film / fiber reinforced composites. We fabricated glass and carbon fiber reinforced composites filled with nano carbon black. The measurements of SE were carried out frequency range from 300MHz to 1.5GHz. It is observed that the SE of the bonded copper mesh and aluminum film. The aluminum film bonded composites showed higher SE compared to that of copper mesh. The aluminum film bonded epoxy composite was shown to exhibit up to 55～75dB of SE. The result that aluminum film bonded composite can be used for the purpose of EMI shielding as well as for some microwave applications.
