Electromagnetic shielding effectiveness of carbon yarn-based woven fabrics

In this study, hybrid and 100% carbon woven fabrics have been investigated for their electromagnetic shielding performance in the frequencies, ranging from 700 MHz to 3 GHz. The shielding effectiveness of plain, twill, and satin woven fabrics was assessed by free space measurement technique. The experimental results showed that carbon-based woven fabrics have an optimum electromagnetic shielding efficiency at different measured frequencies. As expected, the shielding effectiveness of the structure improved with the amount of carbon yarn in the fabric structure. Analyses of the different weave types revealed that twill 2/1 fabric construction showed the best performance compared to the others due to the large number of intersection points of yarns in the fabric structure.

Automated summary

This study investigates the electromagnetic shielding performance of hybrid and 100% carbon woven fabrics in different frequencies. It is found that carbon-based woven fabrics have optimum shielding efficiency at different frequencies. The amount of carbon yarn in the fabric structure improves the shielding effectiveness. Among different weave types, twill 2/1 fabric construction shows the best performance due to a larger number of intersection points of yarns.
