The mechanical properties of the final energetic composite depend mainly on the HTPB prepolymer microstructure; thus, the prepolymer microstructure of HTPB is one of the important factors influencing the mechanical properties of high-energy composite based on HTPB resin. In this paper, the effect of microstructure parameters of HTPB on the behavior and mechanical properties of its high-energy c...
thermomechanical control process steel produced by rolling has a significant anisotropy. the elongated grains and inclusions formed during hot rolling of ferrite and low carbon hsla steels directly influence the anisotropy of the steel’s mechanical properties as a result of microstructural anisotropy. the present research deals with this anisotropy, and particular attention has been paid to the...

V. Lazić, D. Arsić, S. Aleksandrović, A. Ilić, L. Ivanović, M. Djordjević, Faculty of Engineering, University of Kragujevac, Kragujevac, Serbia A. Sedmak, Faculty of Mechanical Engineering, University of Belgrade, Belgrade, Serbia This paper presents the analysis of the influence of temperature on mechanic properties of the base material and welded joints made of high strength steel. The joints...
A protein packaging film was successfully prepared using whey protein concentrate (WPC) as raw material. Protein concentration, plasticizers concentration and temperature were discussed. Research results show that the increasing of protein concentration lead to decreasing barrier properties of WPC film but improving its mechanical properties. Though barrier properties of WPC film lost to some e...
Polymer-based nanocomposites due to their advantages such as corrosion resistance,adequate mechanical properties and low cost are widely used in modern technologies. The increasing application of these nanocomposites, and hence their welding seems unavoidable. In this paper, a novel hottool in friction stir welding process is used for butt welding nanocomposite plates of 5 mm thick containing p...
