Improvement in mechanical properties of carbon fabric–epoxy composite using carbon nanofibers

The cyclic-fatigue behaviour of an epoxy polymer modified with micron-rubber and nano-silica particles

“…The fatigue life enhancement in the ERS polymer was particularly pronounced at the low stress ranges, which is very noteworthy for obtaining extended fatigue lives from components manufactured using such epoxy polymers. It is noteworthy that these results are in agreement with other studies where nanomodified epoxy polymers based upon carbon nano-fibres and nano-silicates have also been shown to exhibit higher fatigue lives, compared to their respective neat epoxy polymers [9,10].…”

Enhancement in Mechanical Properties of Polystyrene Filled with Carbon Nano-Particulates (CNP<sub>S</sub>)

“…It obvious that the micro-hardness increased with the increase in CNP S content and this is attributed primarily to the presence of nano-size reinforcement carbon particulates. This result agrees with the previous fact that addition of small amount of CNP S (<3 wt%) to a matrix system can increase mechanical properties without compromising the processability of the composite [25]. The micro-hardness increased nearly linearly with the CNP S content at ≥0.2 wt%.…”

Application of image processing for quantization and characterization of fabrics with polymeric coatings

“…Literatürde birçok çalışmada belirtilen özellikler ile ilgili ve malzeme içyapısı hakkında bilgi edinmek için taramalı elektron mikroskobu (scanning electron microscopy-SEM), optik mikroskop gibi farklı tiplerdeki görüntüleme cihazları kullanılarak malzemenin yüzey karakterizasyonu gerçekleştirilmektedir. Yapılan bir çalışmada sayısal görüntü isleme teknikleri kullanılarak kompozit malzemelerin SEM görüntülerindeki mikro çatlak ve yıpranma kaybı arasındaki ilişki incelenmiştir [6]. Yine SEM görüntüleri kullanılarak eşikleme işlemleri ile kompozit malzemelerdeki nano tanecik içeriği tahmin edilmiştir.…”
