This study examines the effect of nano-CaCO3 particles on interlaminar shear strength (ILSS) and fracture toughness properties for carbon fiber reinforced epoxy composites. The nano-CaCO3 modified carbon fiber epoxy composites (nC-CFECs) were prepared using the vacuum assisted resin infusion (VARI) method. The short beam shear (SBS) test and single edge notch bending (SENB) test were conducted to calculate ILSS and fracture toughness, respectively. The results illustrate that the introduction of 2% wt. nano-CaCO3 into the epoxy increased the ILSS by up to 24%. Moreover, the fracture toughness in the nanoreinforced composite was 32.3% higher than the unmodified composite. Overall, the nanocomposite material has shown better mechanical performance in terms of ILSS and SENB tests.

Bu çalışma, nano-CaCO3 partiküllerin, karbon fiber takviyeli epoksi kompozitlerin tabakalar arası kayma mukavemeti (ILSS) ve kırılma tokluğu özellikleri üzerindeki etkisini incelemek üzere gerçekleştirilmiştir. Nano-CaCO3 ile modifiye edilmiş karbon fiber epoksi kompozit malzemeler (nC-CFEC) vakum destekli reçine infüzyon (VARI) yöntemi kullanılarak hazırlanmıştır. ILSS ve kırılma tokluğunu hesaplamak için sırasıyla kısa kiriş kesme (SBS) testi ve tek kenar çentik eğilme (SENB) testi yapılmıştır. Sonuçlar, epoksiye ağırlıkça %2 nano-CaCO3 eklenmesinin ILSS 'yi %24'e kadar artırdığını göstermektedir. Dahası, nano-takviyeli kompozit malzemede kırılma tokluğu, nano takviyesiz kompozitten %32.3 daha yüksek bulunmuştur. Genel olarak, nanokompozit malzeme, ILSS ve SENB testleri açısından daha iyi bir mekanik performans göstermiştir.
