Abstract

The internal structures of composites are damaged and therefore their strength decreases significantly, as they are exposed to impact. For this reason, hybrid composite materials containing different types of fiber reinforcements or nanomaterials that are more resistant to mechanical loads are currently being studied. In this study, due to its advantages such as low weight and high strength, aramid/glass fiber reinforced layered hybrid composite plates were produced by vacuum infusion method by adding nano graphene powder into epoxy resin at different weight ratios (0 wt %, 0.20 wt % and 0.25 wt %). The mechanical properties (tensile, three-point bending and impact tests) of the prepared composite test samples were tested. It was observed that the addition of nano graphene powder to layered aramid and glass fiber epoxy composites was effective in increasing the strength of the material. The nano graphene powder added glass and aramid fiber reinforced hybrid composite used at the most ideal values showed an increase of approximately 19.1% in impact strength, 6.4% in tensile strength and 20.4% in bending strength compared to the composite without additive.

Abstract

Kompozit yapılar, darbeye maruz kaldığında, iç yapılarında hasar meydana gelmekte ve bu nedenle, mukavemetlerinde büyük oranda düşüş ortaya çıkmaktadır. Bu sebeple günümüzde mekanik yüklere karşı daha dirençli olan, farklı tip elyaf takviyeler veya nanomalzemeler içeren hibrit kompozit malzemeler üzerinde çalışılmaktadır. Bu çalışmada, düşük yoğunluk ve yüksek mukavemet gibi avantajlara sahip, ağırlıkça farklı katkı oranlarında (%0, %0,20 ve %0,25) nano grafen tozu epoksi reçine içerisine ilave edilerek vakum infüzyon yöntemi ile aramid/cam elyaf takviyeli tabakalı hibrit kompozit plakalar üretilmiştir. Hazırlanan kompozit test numunelerinin, mekanik özelikleri (çekme, üç nokta eğme ve darbe deneyi) test edilmiştir. Aramid ve cam elyaf epoksi kompozitlere nano grafen tozunun eklenmesinin, malzemenin dayanımını arttırmada etkili olduğu gözlenmiştir. Kullanılan nano grafen tozu katkılı cam ve aramid elyaf takviyeli hibrit kompozit, katkısız kompozite göre, darbe dayanımında yaklaşık %19,1, çekme mukavemetinde %6,4 ve eğme mukavemetinde %20,4 artış göstermiştir.
