The effect of friction stirs welding speed on microstructure, mechanical properties and IGC of EN AW-5083 plates
(Advanced Technologies and Materials, 2019)
The aim of this work was to evaluate the influence of welding speed on microstructure, mechanical properties, as well as Intergranular corrosion (IGC) susceptibility of EN AW-5083 alloy welded using FSW. FSW was performed ...
PVB/sepiolite nanocomposites as reinforcement agents for paper
(Srpsko hemijsko društvo, Beograd, 2016)
In order to improve the mechanical properties of paper, 1, 3 and 5 wt. % of sepiolite were dispersed in a poly(vinyl butyral) (PVB) matrix and coated onto the surface of schrenz (110 g m(-2)). Deagglomerated sepiolite ...
Examination of mechanical properties of acrilyc composite materials with different AL2O3 reinforcement by brazil test / Ispitivanje mehaničkih svojstava akrilatnih kompozitnih materijala sa različitim AL2O3 ojačanjima brazilskim testom
(Savez inženjera i tehničara Srbije, Beograd, 2019)
Composite materials based on UV-curing acrylates and various alumina-based reinforcements represent material that is suitable for the use in dentistry, but also in other areas. Composites were made using four different ...
CIRCULAR ECONOMY IMPLEMENTATION IN THE DEVELOPMENT OF FIRE-RETARDANT MATERIALS USED IN CONSTRUCTION, INDUSTRY, AND GENERAL-PURPOSE PRODUCTS
(Association of Metallurgical Engineers of Serbia, 2022)
During a fire, passive fire protection systems are designed to prevent the spread of flames, smoke, and toxic gases. The new fire-retardant (FR) material, used for passive fire protection, is created by combining copolymers ...
Inorganically modified particles FeAl-LDH"SiO2 as reinforcement in poly (methyl) methacrylate matrix composite
(Royal Society Open Science, 2021)
Silica particles were obtained from rice husk to which layered double hydroxide particles were deposited (weight ratio 1 : 1). Fe2+-Al3+ layered double hydroxides (FeAl-LDH) were synthesized by co-precipitation with ratios ...
Effects of poly(vinyl alcohol) blending with Ag/alginate solutions to form nanocomposite fibres for potential use as antibacterial wound dressings
(Royal Society Publishing, 2022)
In this work, nanocomposite fibres and microfibres based on alginate and poly(vinyl alcohol) (PVA) with silver nanoparticles (AgNPs) were produced and characterized for potential application as antibacterial wound dressings. ...
The Effect of Nanofibrillated Tempo-oxidized Cotton Linters on the Strength and Optical Properties of Paper
(Journal of Natural Fibers, 2022)
This study elaborates the application of composite films based on nanofibrillated cellulose obtained from cotton linters oxidized in the 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)/NaBr/NaClO system, with the use ...
Salt template zirconia reinforcing particles as possible reinforcement for PMMA matrix composite
(Sage Publications Ltd, London, 2019)
To obtain flakes like zirconia particles at relatively low temperature, the synthesis method for producing zirconia particles on the surface of salt particles that serve as a template is examined. The produced particles ...
