Abstract

Electromagnetic interference (EMI) is known to cause disruption in electronic devices. This research studies the effect of a wide variety of conductive fibrous and particulate additives in a cementitious matrix for EMI shielding. The EMI shielding tests were conducted in accordance with ASTM D4935-18 standard within a frequency range of 30 MHz to 1.5 GHz. Out of the composite mixes fabricated, the hybrid mixes showed higher level of shielding, hence, developed for 3D printing. The 3D printed specimens with 0.7 wt% carbon fibre and 0.5 wt% activated carbon powder produced an average EMI shielding of 44 dB.
