Electromagnetic interference shielding of composites consisting of a polyester matrix and carbon nanotube-coated fiber reinforcement

High-temperature dielectric and electromagnetic interference shielding properties of SiCf/SiC composites using Ti3SiC2 as inert filler

“…Metal-based materials in the form of thin sheets or sheathing typically serve as excellent EMI shielding agents, but the disadvantages of heavy weight and prone to environmental degradation often make them undesired choices for many current devices [9]. Conversely, carbon-based materials such as carbon nanotubes, carbon black and carbon fibers are generally used as conducting fillers by incorporating them into polymers to form conducting polymer composites for EMI shielding, which are normally lightweight, physical flexible and corrosion resistant [10][11][12][13][14]. Though polymer-based materials offer distinct advantages against metals, it is very difficult to achieve the satisfactory improvements in EMI shielding properties because the high specific surface area of these nanofillers leads to their agglomerations, non-uniform properties and failure to realize their full potentials [15].…”

Stainless steel/polyester woven fabrics and copper/polyester woven fabrics: Manufacturing techniques and electromagnetic shielding effectiveness

“…The incident frequency was between 300 kHz and 3 GHz, and the unit is decibel (dB). EMSE mechanisms can be divided into reflection loss, absorption loss, and multiple reflection loss [20,26]; EMSE is to measure shielding materials for their efficacy against electromagnetic interference and can be calculated by the following equations where E refers to the electric field, M refers to magnetic field, and P is the incident (i) or transmitted (t) power [27,28].…”

“…Most electromagnetic interference shielding materials block and attenuate the incident electromagnetic waves via barriers [20], and as a result, the reflection of electromagnetic waves of highly conductive materials is used to attain an effective EMSE. When radiated to the conductive materials, some of the electromagnetic waves are reflected, thereby decreasing the penetrating energy of the EMI.…”

Hybrid composite low-observable radome composed of E-glass/aramid/epoxy composite sandwich construction and frequency selective surface

“…For stealth technology, the body of a weapons system is generally coated with radar absorbing material (RAM) or microwave shielding materials or constructed with a radar absorbing structure (RAS) composed of composite materials [3][4][5][6][7][8][9]. Because the radar antenna is a major system component that increases the RCS, adoption of stealth technology for the radar antenna is highly effective and indispensable [10].…”
