Electromagnetic Shielding Behavior of CFRP Hybrid Structures

Qing-Qing Ni, Kohta Kashiwagi, Hong Xia


The electromagnetic waves may make our life easier and more comfortable due to its use in the high-speed communication. Recently, polymer composites are extensively employed in EMI shielding for the respected adsorption property of EMI wave. Here, we investigated the EMI property of CFRP with a Cu-mesh in order to obtain a high EMI performance material. The SE and electrical characteristics of the developed composite materials were measured in a flanged coaxial shielding effectiveness test. The behavior of the electromagnetic wave shielding in CFRP /Cu-mesh composites was evaluated and discussed by the measured experimental results, and an optimum hybrid structure for high performance of EMI is designed.
