Fiber Takviyeli Silindirik Kabuğun Ekranlama Etkinliğinin Analizi ve Simülasyonu

“…12(1): 10-17 (2021) Analysis and Simulation of Shielding Effectiveness of a Fiber Reinforced Cylindrical Shell 11 tection of electronic equipment from the effects of external sources like High-Intensity Radiated Fields (HIRF), Lighting and High Altitude Electromagnetic Pulse (HEMP) is an important issue against involuntary electromagnetic interference (EMI) (Perala et al, 1991;Cordill et al, 2011;Aziz et al, 2012;Jazzar et al, 2014;Gutiérrez et al, 2014;Vogel, 2014;Bui et al, 2015;Nunes and Schuur, 2015;Cabello et al, 2017;Huang et al, 2017). The aircraft/spacecraft manufacturing industry is one of the areas that reinforced composite materials are widely used as a replacement for metals.…”

“…The aircraft/spacecraft manufacturing industry is one of the areas that reinforced composite materials are widely used as a replacement for metals. The new composite materials like Composite material skin(CMS) (Aziz et al, 2012), Carbon fiber reinforced polymer(CFRP) (Bui et al, 2015;Abdelal, 2018;Munalli et al, 2019), Carbon fiber reinforced composites (CFRC) (De Rosa et al, 2009;Greco et al, 2012) and Graphite-epoxy (GrEp) (Bogorad et al, 2008) are used in aircraft/spacecraft construction. Instead of the physical and chemical advantages of these materials, the electrical conductivity of the composite materials is much lower than those metals (Evans, 1997).…”

Shielding Performance of Composite Materials Used in Air Vehicles

“…Involuntary electromagnetic interference(EMI) is an important issue for the protection of electronic equipment of aircraft from the effects of external sources like High-Intensity Radiated Fields(HIRF), Lighting(LEMP) and Electromagnetic Pulse(EMP) [1][2][3][4][5][6][7][8][9][10]. The aluminum skin of air vehicles provides important level of shielding effectiveness(SE) performance against external EMI sources [1].…”

“…In these studies, it has been an important issue to reduce the production cost by reducing the weight of the air vehicles and to prevent the increase of electromagnetic interference [3], [9], [11][12][13][14][15][16]. With the advantages like lower weight, good mechanical and thermal characteristics, lower maintenance costs, lower corrosion and higher hardness, the use of composite materials such as Composite material skin(CMS) [2], Carbon fiber reinforced polymer(CFRP) [9], [16][17], Carbon fiber reinforced composites(CFRC) [15], [18] and Graphite-epoxy(GrEp) [19] as a replacement of metals on aircraft manufacturing industry increases rapidly. Multilayered composite materials show good shielding performance as surface the aircraft (> 20 dB) and can provide protection against EMP and electromagnetic interference [20].…”
