Electromagnetic shielding effectiveness of carbon

2018/3/19Carbon fabric composite is used in technical applications such as aircrafts in which electromagnetic shielding (electromagnetic interference–shielding effectiveness) is required. Traditionally, metallic coatings or metal plates are used for electromagnetic shielding, however, conductive filler-filled composite is also alternative to metal sheets due to its light weight.

The higher value of conductivity has a positive effect on the electromagnetic interference (EMI) shielding effectiveness (SE) of the CF. The EMI SE increased with increasing NSIP content in CF. The specific SE of the light weight CF was 130 dB.cm 3 /g at 10 wt% of ferrocene in CF, which is the highest value reported so far for CF, particularly at such a low thickness (2.75 mm).
