Some Features of Doping of Nano–Graphite in Natural Coir Fibre Epoxy Composites

Öz

Nanokompozit polimerlerin, biyomedikal mühendislik, elektronik yapı mühendisliği ve daha birçok çeşitli sektör de; bilim ve teknolojideki yeni gelişmeler nedeniyle doğrudan/dolaylı kullanımları girişimde bulunulmuştur. Biz bu araştırmada, doğal hindistan cevizi lifi takviyeli polimer kompozitlerinde nano-grafitin katkısını kullandık. Kullanılan kompozit numuneleri, ağırlık fraksiyonu ile bir epoksi reçine matrisinde% 45 doğal hindistan cevizi lifi ve% 3.2 nano-grafit (N-G) idi. Doğal hindistan cevizi lifi içindeki % nano-grafit ağırlığının üzerinde doping yaptığımız da gerilme mukavemetinin kabaca % 45-50 ve geri kalanının mekanik özelliklerin ise ortalama 2-3 kat arttığını bulduk. Son olarak, SEM analizi ile mevcut lif elyafı kompozit numunelerinde nano grafitin iyi bir dağılımını ortaya koyduk.

Some Features of Doping of Nano–Graphite in Natural Coir Fibre Epoxy Composites

Abstract

An attempt has been made to find some direct/indirect uses of nonocomposite polymers in varios sectors such as; biomedical engineering, electronics, structural engineering and many more due new advancement of science and technology. In the present research work, we used the doping of nano-graphite in the natural coir fibre reinforced polymer composites. The used samples of composites were 45 % of natural coir fibre and 3.2 % of nano-graphite (N-G) in an epoxy resin matrix by weigth fraction. We find that on doping the above % weight of nano-graphite in the natural coir fibre, the tensile strength roughly increased by 45-50 % and the rest of the mechanical properties by 2-3 times on the average. And finally, the SEM analysis revealed a good dispersion of nanographite in the present samples of composite of coir fibre.
