AB  - Carbon fibers (CFs) are indispensable materials in our daily life. Theexcellent bearing capacity, remarkable dielectric property, ease ofproduction, and corrosion resistance of CFRP composites distinguishthem from all other options in addition to them, CFRPs may also shieldfrom electromagnetic interference (EMI). In this study, two-layer CFreinforced epoxy composites reinforced with two different hematite(alpha- Fe2O3) and goethite (FeO(OH)) particle sizes of 50 nm and 45μm (325 mesh) were produced using the manual lay-up method. Then,far field electromagnetic shielding effectiveness (SE) with 700 MHz -6000 MHz range were examined. The maximum shielding effectivenesswas determined to be at 5200 MHz with 39.28 dB for 5 wt.% FeO(OH),at 4700 MHz with 38.38 dB for 10 wt.% Fe2O3(325 mesh), at 3800 MHzwith 37.15 dB for 15 wt.% Fe2O3(50 nm).

N2  - Karbon fiber (carbon fiber: CF) katkılı malzemeler, günlük hayatımızdavazgeçilemez malzemelerdir. CF takviyeli kompozitlerinin (CFRP) üstünmukavemeti, yüksek dielektrik özelliği, üretim kolaylığı ve korozyondirenci, CFRP’leri diğer malzemelerden öne çıkaran özelliklerindenyalnızca birkaçıdır. Bu çalışmada partikül boyutları 50 nm ve 45 μm(325 mesh) olan iki farklı hematit (alfa-Fe2O3) ile götit (FeO(OH))takviyeli, 2 katmanlı CF takviyeli epoksi kompozitler el ile yatırmayöntemi kullanılarak üretilmiştir. Üretilen kompozitler 700 MHz-6000MHz aralığında uzak alan elektromanyetik kalkanlama özelliklerinitespit etmek için testlere tabi tutulmuşlardır. Maksimum kalkanlamaetkisi, ağırlıkça %5 FeO(OH) takviyeli kompozit için 39.28 dB ile5200 MHz'de, %10 Fe2O3(325 mesh) takviyeli için 38.38 dB ile 4700MHz’de, %15 Fe2O3(50 nm) takviyeli için 37.15 dB ile 3800 MHz’debelirlenmiştir.
