“…This value is found superior compared to other work by several authors (Table I) except the work carried out by Rahman et al 16 who reported EMI-SE of ∼60 dB at 50 phr (part per hundred part of resin) of carbon black (CB) in a blend of ethylene vinyl acetate (EVA) and acrylonitrile-butadiene copolymer (NBR) for 5 mm thick sample. However, there are several reports 30,31 indicate that high loading of CB degrades the mechanical properties of polymer. In addition to degradation of mechanical properties, such a high thickness (5mm) of the material is not commercially viable for some applications where 2-3 mm thickness is preferred.…”

In this letter, we report preparation of strongly anchored multiwall carbon nanotubes (MWCNTs) carbon fiber (CF) fabric preforms. These preforms were reinforced in epoxy resin to make multi scale composites for microwave absorption in the X-band (8.2-12.4GHz). The incorporation of MWCNTs on the carbon fabric produced a significant enhancement in the electromagnetic interference shielding effectiveness (EMI-SE) from −29.4 dB for CF/epoxy-composite to −51.1 dB for CF-MWCNT/epoxy multiscale composites of 2 mm thickness. In addition to enhanced EMI-SE, interlaminar shear strength improved from 23 MPa for CF/epoxy-composites to 50 MPa for multiscale composites indicating their usefulness for making structurally strong microwave shields
