Investigation of Electromagnetic Shielding for Wire Mesh Composite for Aircraft against Lightning Strike

Composite Materials for Electromagnetic Interference Shielding

This paper demonstrates that the addition of chemical agents and carbon fibers to cement can greatly enhance the shielding effectiveness of the concrete. In addition to improving the shielding effectiveness, carbon fibers and chemical agents enhance the tensile and flexural strengths significant ly. As both carbon fibers and steel fibers are electrically conductive, both can be added to cement ...

Emerging technology for shielding of electromagnetic radiation using composite materials

This study indicated that multi-walled carbon nanotubes (MWCNTs)-epoxy composites can be used as effective lightweight shielding materials. The measurement results showed that highest EMI SE of 23.4 dB at 8 GHz was obtained for nanocomposite with 1 wt% MWCNTs. Dielectric properties and electrical conductivity values were supplemented by microscopic studies.

Electromagnetic Interference Shielding Characteristics for Stainless Wire Mesh and Number of Plies of Carbon Fiber Reinforced Plastic

In this paper, the electromagnetic shielding characteristics of an up-to-date typical carbon filler material, carbon fiber used with a metal mesh were investigated. Carbon fiber 12k-prepregs, where carbon fibers were impregnated with epoxy, were laminated with wire meshes, vacuum bag-molded and hardened to manufacture hybrid-type specimens, with which an electromagnetic shield test was performe...

Computational Electromagnetic Modeling and Experimental Validation of Fuel Tank Lightning Currents for a Transport Category Aircraft

A full scale aircraft lightning test campaign was conducted to support compliance with AWM 525.981 through validation of computational electromagnetic (CEM) models. The aircraft is injected with different lighting current attachment scenarios while measurements of currents, voltages and magnetic fields focused in the composite wing area. The high fidelity aircraft model has been resolved with E...
