Bu çalışmada grafen nanopul takviyesinin E-cam
lifi/epoksi tabakalı kompozit malzemenin esneklik mukavemeti üzerine etkisi
deneysel olarak araştırılmıştır. Grafen
nanopul takviyeli ve takviyesiz, [0^o/90^o]_3S fiber oryantasyonuna sahip
kompozit malzemeler el yatırma ve vakum torbalama yöntemiyle imal edilmiştir.
Epoksi içerisine ağırlıkça üç farklı oranda (% 0.25, 0.5 ve 1) grafen nanopul
eklenmiştir. Üretimi yapılan plakalar su jeti kesme makinasıyla kesilerek üç
nokta eğme test numuneleri elde edilmiştir. Daha sonra ASTM D790 standardına
göre üç nokta eğme testleri yapılmıştır. Destek silindirlerinin merkezleri
arasındaki mesafe/kompozit numune kalınlığı oranı (s/t) tüm testlerde 16 olarak
seçilmiştir. Elde edilen sonuçlara göre epoksi matris içerisine grafen nanopul
eklenmesi, tabakalı kompozit malzemenin esneklik mukavemetini artırmıştır. Epoksi matris
içerisine ağırlıkça % 0.25, 0.5 ve 1 oranlarında grafen nanopul katıldığında
esneklik mukavemetinde sırasıyla % 4.32, 12.88 ve 7.03’lük bir artış olmuştur.

Flexural Behavior of Graphene Nanoplatelets Reinforced Cross-Ply E-glass/epoxy Laminated Composite Materials

Öz

In this study, the
effect of graphene nanoplatelets reinforcement on the flexural strength of E-glass/epoxy laminated composite material
was investigated experimentally. [0⁰/90⁰]_3S oriented composite
materials with and without graphene nanoplatelets reinforcement were
manufactured by using hand lay-up and vacuum bagging method. Graphene nanoplatelets at three different ratios
(0.25, 0.5 and 1 wt.%) were added to the epoxy. The produced plates were cut
with a water jet cutting machine to obtain three-point
bending specimens. Then, three-point bending tests were performed according to the
ASTM D790 standard. The span between the centers of support cylinders/composite
specimen thickness ratio (s/t) was selected as 16 in all the tests. Results
indicate that the addition of graphene nanoplatelets to the epoxy matrix
increased the flexural strength of the laminated composite material. When the graphene nanoplatelets at ratios of 0.25,
0.5 and 1 wt.% were added to the epoxy
matrix, the flexural strengths increased by 4.32%, 12.88% and 7.03% respectively.
