Nylon-66 Nanofiber Interleaved Carbon Epoxy Composites for EMI Shielding Applications

Abstract

Polymer composites with conducting fillers are extensively used as replacement to metals in EMI shielding enclosures. Polymer-Carbon composites belong to this category and they possess very high mechanical strength with proven track record in automobile and space applications. These composites are investigated for EMI shielding applications. The EMI shielding effectiveness and parameters like skin depth and attenuation constant are discussed in this paper to highlight the advantages of using carbon composites for EMI shielding applications. To improve the flexibility of these composites, nylon-66 nanofiber interleaving of the carbon epoxy composites was used and its effect on the EMI shielding effectiveness is discussed. The deployment of these composites for EMI shielding applications in the field of high voltage engineering is suggested.
