Tensile properties of fiber-resin composites that consist of polyarmid fiber (Kevlar 129) and poly(vinilbutyral) / Zatezna svojstva polimernog kompozitnog materijala poliaramidna vlakna (Kevlar 129) - poli(vinilbutiral)(PVB)
(Savez inženjera metalurgije Srbije, Beograd, 2006)
Thanks to fact that composite material have usefully characteristic two or more materials, they are becoming more and more substitute standard materials in every field of technique they start to. In this study static ...
Saw surfacing of the worn part of crane wheel with flux cored wire / Navarivanje EPP-postupkom istrošenog dela točka dizalice primenom punjene žice
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2006)
This paper presents results of repairing a ring part and rolling surfaces of the crane wheel by SAW method with flux cored wire. Optimal quality of flux cored wire for crane wheel repairing is defined by weld metal hardness ...
Influence of Cu on the mechanical properties of an Al-4.4wt%Mg alloy after ECAP
(Trans Tech Publications, Ltd., 2006)
Two Aluminium alloys, type AA5182 and AA5182+1.2wt% Cu, have been studied. The
second alloy in solution treated condition is 18% stronger than the first one. During ageing at 150°C or 200°C it shows a characteristic fast ...
The validity of the general similarity law for electrical breakdown of gases
(IOP Publishing Ltd, Bristol, 2006)
This paper investigates the validity of the similarity law in cases of dc and pulse breakdown of gases. Geometrically similar systems insulated with SF6 gas were used during experiments. It is shown that the similarity law ...
The effect of TiO 2 on the structure and devitrification behavior of potassium titanium germanate glass
(Springer Netherlands, 2006)
The effect of replacing 20 mol% of GeO 2 by TiO 2 on the properties of potassium germanate glass was investigated. The structure and devitrification behaviour of glasses were studied by Fourier transform infrared spectroscopy ...
Karakteristike kvašenja pletenina na bazi konoplje namenjenih za medicinske svrhe / Liquid wetting properties of hemp based knitted fabrics for hospital uses
(Savez inženjera i tehničara tekstilaca Srbije, 2006)
U okviru ovog rada pletenine na bazi konoplje podvrgnute su ispitivanju maksimalnog kapaciteta apsorpcije tečnosti kao i brzine njene apsorpcije. S obzirom da su za izradu pletenina upotrebljene nehomogene kompleksne pređe ...
