Electromagnetic shielding properties of woven fabrics made from high-performance fibers

Abstract

The expansion of the electronic industry and the extensive use of electronic equipment in communications, computations, automations, biomedicine, space, and other purposes have led to problems such as electromagnetic interference of electronic devices and health issues. For the reasons given above, the demand for the protection of human beings and sensitive electronic and electrotechnic appliances against the undesirable influence of electromagnetic signals and troublesome charges has been increasing. This paper presents the present state of fabrication and characterization of multifunctional high-performance metal/ m-aramid hybrid fabrics with increased resistivity to electromagnetic smog while preserving basic properties of textile structures designated for clothing or technical purposes. In this paper, hybrid electromagnetic shielding fabrics made of high-performance fibers are introduced. An effect of metal content is studied and a form of relation between resistivity and total shielding effectiveness is proposed. Furthermore, chosen mechanical properties of developed fabric are evaluated.
