AB  - Impact resistant nanocomposites are recognized as promising in saving lives in the car, skiing and bicycle accidents, preventing the failure of polymer-based prostheses and orthotic devices, as well as for various defense applications. This research reports improved impact and ballistic resistance of composite materials based on p-aramid fabric impregnated with phenolic resin and poly (vinyl butyral) (PVB), reinforced with small amounts of inorganic fullerene-like nanoparticles of tungsten disulfide (IF-WS2) and multiwall inorganic nanotubes (INT-WS2). The evaluation of the tensile testing resulted in significant improvements in the tensile strength (24.7%) and toughness (64.1%) for the composites with the addition of only 0.3 wt% INT-WS2 nanotubes. The impact toughness increased by 35.8%; the back-face deformation depths after shots were reduced by 12%; the absorbed energy of the knife stab 8.5% higher and the deformation depth 40.4% smaller than for the sample without the nanoreinforcement. The reaction of the composite material to shot impact was recorded by high-speed and infrared camera, to observe heating and cooling rates of the sample caused by dissipation of the kinetic energy of the shots.

AB  - Combination of phenolic resin with poly (vinyl butyral), PVB, is often used as impregnation of aramid fabrics in prepregs for the ballistic protection products. In this study an effect of inorganic fullerene-like tungsten disulfide nanoparticles (IF-WS2) in aramid/phenolic resin/PVB composite for improving its viscoelastic and mechanical properties is examined. The effect of IF-WS2 on mechanical properties improvement was first proved by nanoindentation on thin film samples PVB/IF-WS2. The quality of aramid fabrics impregnation with PVB/phenolic resin/IF-WS2, and the nanoparticles dispersion were analyzed by scanning electron microscope with energy dispersive spectrometer. Viscoelastic properties of the composites were examined by dynamic mechanical thermal analysis, observing the storage and loss modulus, mechanical loss factor and glass transition temperature versus temperature and frequency. Time-temperature superposition principle was applied for the construction of master curves. IF-WS2 causes increase of glass transition temperature and improvement in mechanical properties of examined composites.

AB  - This paper reports the characteristics of the explosive TH-5, recycled (recovered) trinitrotoluene (TNT) with max. 5wt-% of hexogen (RDX). The explosive TH-5 was obtained by delaboration of warheads and melting of explosive charges based on TNT and RDX and by separation (extraction) of high explosive components. The thermal characteristics of pure (virgin) TNT and RDX, and recycled explosive TH-5 are determined by differential scanning calorimetry. The possibility of processing TH-5 by pressing and casting is also examined. The comparative analysis of sensitivity of TH-5 and TNT to friction is determined, as well as compressibility of explosives, and the detonation velocity of pressed and cast charges. Based on the analysis of experimental results, the defense standard requirements for the quality of TH-5 are defined and possibility of practical application of explosive TH-5 was estimated.

AB  - A possibility of using inorganic fullerene-like tungsten disulfide, IF-WS2, nanoparticles as a filler in poly (vinyl butyral), PVB, for improving its thermal and rheological properties is examined. PVB is a thermoplastic polymer with excellent properties, widely used: in ballistic protection, for protection of safety glass, in metal primers and coatings, temporary binders. Two different molecular weights of PVB were previously examined in this research: Mowital B60H and B75H. Both grades of PVB were dissolved in different solvents: ethanol and 2-propanol. Thin films were prepared by solvent casting technique. The glass transition temperature (Tg) of the tested samples was determined using differential scanning calorimetry (DSC), at three different heating rates (5°C/min, 10°C/min and 20°C/min). After choosing a solvent and PVB grade, IF-WS2 nanoparticles were added to PVB solutions and dispersed by ultrasonic irradiation. Compatibility, i.e. interaction of IF-WS2 with the dissolved PVB was examined by microcalorimetry method. The nanoparticles dispersion and deagglomeration in matrix of PVB was analyzed by scanning electron microscope (SEM). The effect of IF-WS2 on rheological properties of the chosen samples has been examined using Dynamic Mechanical Thermal Analysis (DMTA), observing storage modulus, loss modulus and the loss factor as functions of temperature for the tested composites.

U ovom istraživanju najpre su ispitane dve različite molekulske mase PVB: Mowital B60H i B75H. Rastvoreni su u različitim rastvaračima: etanol i 2- propanol.

Nakon izbora optimalnog rastvarača i molekulske mase PVB, IF-WS2 nanočestice su dodate u rastvor PVB i ultrazvučno dispergovane. Kompatibilnost, odnosno interakcija IF-WS2 sa rastvorenim PVB je ispitana metodom mikrokalorimetrije. Deaglomeracija nanočestica i disperzija u matrici PVB su analizirane pomoću skenirajućeg elektronskog mikroskopa.

AB  - The subject of this research is to explore the possibility of preparation of nanocomposite material of improved thermo-mechanical and tribological properties, using inorganic fullerene-like tungsten disulfide nanostructures (IF-WS2) as reinforcement in poly(vinyl butyral) (PVB). This paper also reports investigation of the effects of using different solvents in preparation of PVB/IF-WS2 nanocomposite on the thermo-mechanical behavior of the resulting material. PVB was dissolved in ethanol, isopropanol, n-butanol and ethyl acetate. IF-WS2 nanoparticles were added to these PVB solutions and dispersed by different deagglomeration techniques. Samples were dried and thin films were obtained. Their microstructure and the quality of IF-WS2 dispersion and deagglomeration in PVE matrix was analyzed by scanning electron microscope (SEM). The reinforcing effect of IF-WS2 is examined by determining hardness, reduced modulus of elasticity and coefficient of friction, by nanoindentation and nanoscratch test, in terms of the different solvents applied in preparation of the samples, mode of stirring and different contents of IF-WS2. The glass transition temperature (T-g) was determined for the prepared samples using differential scanning calorimetry (DSC) and dynamic mechanical thermal analysis (DMA). Storage modulus and mechanical loss factor were observed in a defined temperature range using DMA.

AB  - The world-wide use of pesticides together with the possibility of chemical warfare agent's usage in military actions, terrorist attacks or in accidents, increased the risks of chemical contamination occurrence and consequently stipulated the need for the development of new protective materials and equipment with improved properties. Because of that, today in the world, research are directed toward design of the so-called "smart textiles", which are capable of "self-decontamination", i.e. decomposition of toxic chemicals. Therefore, we investigated two methods for the synthesis of TiO2 nanoparticles and their deposition on the standard military textiles (cotton/polyester 50%). Photocatalytic activity of such obtained textiles was tested by degradation of organic dye methyl orange (MeO) and chemical warfare agent O-ethyl S-(2-diisopropylamino)ethyl methylphosphonothiolate (VX), along with the evaluation of their mechanical properties, tearing strength, tensile strength and air permeability.
