Hybrid composites are
the material group largely preferred for use in space, aerospace and ballistic
applications, where superior mechanical properties and low density are
required. Hybrid composites produced using high-strength Kevlar fiber and
S-glass fiber materials and nano particle added matrix in this study. Nineteen
combinations of hybrid composite materials were produced using three matrix
materials—nano-calcite, nano-clay and carbon nano-tube which have high-energy
absorption properties. To compare the ballistic test results of hybrid
composites, 1 control sample were tested. Nano particles were added into the
composites in the ratio of 0.5, 1 to 2 percent, corresponding to the ratios
that achieved the most desirable mechanical properties in other literature.
Deflections occurring at composites’ back surfaces were measured after tests
and evaluation of whether there would be perforation was done. As a result of
this study, was seen that ballistic strength positively affected with nano
particle addition and different stacking sequences of composite layers. In
hybrid composites produced by S-glass reinforcement, the weight decreased by
20% while the ballistic strength decreased significantly. It was found that
calcites adding hybrid composite plates at the front sites and clay added
plates at the back sites showed superior ballistic performance. It was observed
that the ballistic strength of hybrid composites increased with increasing
calcite ratio at the front sites.

Hibritleştirmenin Nano Takviyeli Hibrit Kompozit Plakaların Balistik Darbe Davranışlarına Etkisi

Öz

Hibrit kompozitler, özellikle yüksek
mekanik özelliklere karşılık düşük yoğunluk istenen havacılık, uzay ve balistik
uygulanmalarda en çok tercih edilen malzeme çeşididir. Hibrit kompozitler bu
çalışmada, takviye malzemesi olarak, yüksek dayanımlı Kevlar fiber ve S-cam fiber
olarak kullanılmıştır. Matris olarak ise yüksek enerji emilimi sağlayan
sağlayan üç tip (nano-kalsit, nano-kil ve nano-karbon tüp) kullanılarak 19 farklı
kombinasyonda hibrit kompozit malzeme üretilmiştir. Hibrit kompozitlerin
balistik test sonuçlarını karşılaştırmak için 1 nano malzeme takviyesi olmayan
kontrol numunesi test edilmiştir. Nano-parçacıklar dolgu malzemeleri kompozit
malzeme içerisine 0,5, 1 ve % 2 oranlarında, literatürden elde edilen maksimum
mekanik özelliklere karşılık gelen optimum oranlarda katılmıştır. Testler
sonrası malzeme arka yüzeyinde meydana gelen çökme değerleri ölçülmüş ve
malzemede delinme olup olmama durumu değerlendirilmiştir. Çalışma sonucunda,
nano parçaçık takviyesi yapılarak malzemenin balistik dayanımının
arttırılabileceği, sıralamanın değiştirilmesiyle birlikte balistik dayanımın
arttığı görülmüştür. S-glass eklenerek üretilen hibritlerde, ağırlık %20
oranında düşürülse de, balistik dayanım azalmıştır. Kalsit takviyeli plakaların
ön yüzeyde, kil takviyeli tabakaların arka yüzeyde olduğu durumda balistik
dayanım artmıştır. Kalsit miktarının arttırılmasıyla birlikte malzemenin
balistik dayanımı artmıştır.
