AB  - This study presents an analysis of films which consist of two layers; one layer is PVDF as the matrix, along with fillers BaTiO3 (BT), and the second is one bacterial nanocellulose (BNC) filled with Fe3O4. The mass fraction of BT in PVDF was 5%, and the samples were differentiated based on the duration of the mechanical activation of BT. This innovative PVDF laminate polymer with environmentally friendly fillers aligns with the concept of circular usage, resulting in a reduction in plastic content and potential improvement of the piezoelectric properties of the entire composite. This work presents new, multifunctional “green” packaging materials that potentially could be a good alternative to specific popular materials used for this purpose. The synthesis of the films was carried out using the hot press method. Tensile tests, water vapor permeability examination, and structural analyses using SEM-EDS and FTIR have been conducted. The sample PVDF/BT20/BNC/Fe3O4 exhibited the best barrier properties (impermeability to water vapor), while the highest tensile strength and toughness were exhibited by the PVDF/BT5/BNC/Fe3O4 sample.

AB  - In this study, silicate nanofillers; dicalcium silicate, magnesium silicate, tricalcium silicate, and wollastonite; were synthesized using four different methods and incorporated into the epoxy resin to improve its mechanical properties. Characterization of the newly synthesized nanofillers was performed using Fourier-transformation infrared (FTIR) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The purpose of this study was to analyze newly developed composite materials reinforced with silicate nanoparticles utilizing tensile testing and a full-field non-contact 3D Digital Image Correlation (DIC) method. Analysis of deformation and displacement fields gives precise material behavior during testing. Testing results allowed a more reliable assessment of the structural integrity of epoxy composite materials reinforced using different silicate nanofillers. It was concluded that the addition of 3% of dicalcium silicate, magnesium silicate, tricalcium silicate, and wollastonite lead to the increasement of tensile strength up to 31.5%, 29.0%, 27.5%, and 23.5% in comparison with neat epoxy, respectively. In order to offer more trustworthy information about the viscoelastic behavior of neat epoxy and composites, a dynamic mechanical analysis (DMA) was also performed and rheological measurements of uncured epoxy matrix and epoxy suspensions were obtained.

AB  - Halloysite nanotubes (HNTs), naturally occurring as aluminosilicate nanoclay mineral, have recently emerged as a possible nanomaterial for countless applications due to their specific chemical structure, tubular shape, high aspect ratio, biocompatibility and low toxicity. In this study, HNTs were incorporated into the epoxy resin matrix to improve its mechanical properties and thermal stability. However, heterogeneous size, surface charge and surface hydrogen bond formation, result in aggregation of HNTs in epoxies to a certain extent. Three specific techniques were used to integrate HNTs into neat epoxy resin (NE). The structure and morphology of the embedded nanotubes were confirmed by Fourier-transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD). Tensile testing was carried out and the fractured surface of the tested specimen was analysed using scanning electron microscopy (SEM). The thermal stability of the prepared nanocomposite materials was investigated by thermogravimetric (TG) and derivative thermogravimetry (DTG) studies. The obtained results indicated that improved properties of HNTs/epoxy nanocomposite materials were related to the unique properties of well-dispersed HNTs, agglomerate scale, and reduced void presence, and could be controlled by the manufacturing processes.

AB  - The paper presents static and dynamic tests of carbon/epoxy composite materials with fiber orientation at 0 degrees/90 degrees and +/- 45 degrees. The main tensile properties were determined as a basis for subsequent dynamic tests, in which permanent dynamic strength, crack growth, and crack growth rate in the material due to the action of fatigue load were assessed. Comparisons were made regarding the structure of the tested specimens. Samples were obtained from prepregs with a specific density of 1600 kg/m(3). The tests were performed at room temperature. Scanning electron microscopy (SEM) was used to analyze the damage in the material during these tests, the mechanisms of their further damage progression and, the impact on the growth and growth rate of the initial crack in the material. The analysis of numerical results and micromechanical analysis confirmed the dominant role of the reinforcing structural element in the material in all performed tests. The obtained results are of great importance in the application of composite materials of such structures under different operating conditions and load regimes.

AB  - The basic subject of this paper was the determination of the strain distribution in glass-polyester composite pipes subjected to internal pressure. Firstly, the test was performed on virgin pipe segments (without the influence of acidic solution) to determine the original properties of the examined composite pipes. Subsequently, the pipes were subjected to the influence of 25% acidic solution. Phosphoric and nitric acid were chosen, because of their frequent use in chemical industry, either as reactants or as products. The pipes were made by 'filament winding' method, with the angles of the glass fibers reinforcement [90°]2[±55°]4[90°]4. The tests were performed by subjecting the polymer composite pipes to internal pressure; the strain values were determined by strain gages in three directions: 0°, 90° and ± 45° with respect to the pipe axis. The tests were performed until the leakage occurred, up to the pressure value of approximately 100 bar, i.e. until the occurrence of the first cracks. Also, the micromechanical analysis on fracture surfaces was done by Scanning Electron Microscopy (SEM), which provided the knowledge about models and mechanisms of fracture due to the applied loading.
AB  - Cilj ovog rada je određivanje raspodele deformacija kod staklo-poliestar kompozitnih cevi koje su istaložene dejstvu unutrašnjeg pritiska. Prethodno su izvršena ispitivanja na netretiranim cevima u cilju određivanja originalnih svojstava. Zatim su cevi tretirane 25%-im rastvorom kiselina. Upotrebljene su fosforna i azotna kiselina zbog njihove česte upotrebe u hemijskoj industriji.

AB  - Synthesis of high-performance alkyd resins (ARs) based on waste poly(ethylene terephthalate) (PET) glycolyzates is presented. PET glycolyzates were synthesized by catalytic depolymerization with trimethylolpropane (TMP) and trimethylolethane (TME) and used as replacement of polyhydroxylic component during the ARs synthesis. The obtained glycolyzates and produced ARs were analyzed using FTIR, 1H and 13C NMR spectroscopy and acid, iodine, and hydroxyl value were determined. Rheological properties of the synthesized ARs, as well as, thickness, adhesion, hardness and the gloss values were determined. All synthesized ARs show good adhesion and hardness and the gloss values are greater than 95%. The influence of the addition of vinyl modified nanosilica Aerosil® R380, functionalized with 3-(trimethoxysilyl)propyl methacrylate (TMSPM) and tris(2-methoxyethoxy)(vinyl)silane (TMEVS), on the mechanical and anticorrosive characteristics of the prepared nanocomposite coatings, based on ARs, was investigated.

Orientations were 0/90° i ±45°. In accordance with appropriate standards, tensile strength and modulus of elasticity were determined. Beside the analysis of the results obtained during the experiment, micro-mechanical analysis of the tensile failure appearance and development was conducted based on the observed cracked surface, which led to a confirmation of all characteristic mechanisms and cracks expected for this type of material and study.

AB  - Polymers are the most studied viscoelastic material. The shorter times (high frequencies) corresponding to lower temperatures and long times (low frequencies) to high temperatures. This represents the quantitatively applied time-temperature superposition (TTS).

AB  - The use of composite material increases. Composite materials are used in a wide range of applications such as automotive, aerospace and other industries. But they have not been properly recycled, due to their inherent nature of heterogeneity. The current and future waste management and environmental legislations in EU require all engineering materials to be properly recovered and recycled from end-of-life (EOL) products. Recycling will ultimately lead to resource and energy saving. This work presents different possibilities for recycling composite. Various technologies have been developed: mechanical recycling, thermal recycling, and chemical recycling, depending on the applied operations during the recycling process. Mechanical recycling techniques involve the use of grinding techniques to comminute the scrap material and produce recycled products in different size ranges suitable for reuse as fillers or partial reinforcement in new composite material. Thermal techniques involve the use of heat resulting in releasing certain amounts of energy. Chemical recycling involves the process for chemical depolymerisation or removal of the matrix by using chemical dissolution reagents for liberation of fibres which can be reused. The removed matrix can process a useful product using a specific chemical procedures. However a lack of adequate markets, high recycling cost, and lower quality of the recyclates are the major commercialization barriers.

AB  - The significance of composite materials and their applications are mainly due to their good properties. This imposes the need for their recycling, thus extending their lifetime. Once used composite material will be disposed as a waste at the end of it service life.

This indicates a great importance of recycling as a method of the renowal of composite materials. This study represents a contribution to the field of mechanical properties of the recycled composite materials. The tension mechanical properties (tensile strength and modulus of elasticity) of once used and disposed glass-epoxy composite material were compared before and after the recycling. The obtained results from mechanical tests confirmed that the applied recycling method was suitable for glass-epoxy composite materials.

First, the impact test was performed on virgin samples (without the influence of any liquid) to obtain knowledge about the original material properties. Subsequently, the specimens were soaked in water and in alkaline and acidic solutions: sodium hydroxide, ammonium hydroxide, phosphoric acid, and nitric acid. The specimens were left in each liquid for 3, 10, 30, and 60 days at room temperature. The impact toughness and the crack initiation and propagation energies were recorded for all samples. A comparison of the results was made based on the pH values of the aggressive media, as well as based on the original impact properties and number of days of treatment. This way, the service life of pipes for transport of theexamined solutions could be predicted. POLYM. COMPOS., 2012.

AB  - Construction materials, traditionally used in process equipment, are today successfully replaced by composite materials. Hence, many pipes are made of these materials. The subject of this study was the influence of liquids on the state of stresses and tensile strengths in the longitudinal and circumferential direction of glass-polyester pipes of a definite structure and known fabrication process. These analyses are of great importance for the use of glass-polyester pipes in the chemical industry. The tensile properties (the ultimate tensile strength and the modulus of elasticity) were tested and determined for specimens cut out of the pipes; flat specimens for the tensile properties in the longitudinal direction and ring specimens for the tensile properties in the circumferential direction. First, the tension test was performed on virgin samples (without the influence of any liquid), to obtain knowledge about the original tensile properties of the material composite studied. Subsequently, the specimens were soaked in alkaline solutions: sodium hydroxide (strong alkali) and ammonium hydroxide (weak alkali). These solutions were selected because of their considerable difference in pH values. The specimens and rings were left for 3, 10, 30 and 60 days in each liquid at room temperature. Then, the samples were tested on tension by the standard testing procedure. A comparison of the obtained results was made based on the pH values of the aggressive media in which the examined material had been soaked, as well as based on the original tensile properties and the number of days of treatment. Micromechanical analyses of sample breakage helped in the elucidation of the influence of the liquids on the structure of the composite pipe and enabled models and mechanisms that produced the change of strength to be proposed.

Cevi su definisane strukture i poznatog procesa proizvodnje. Ove analize su od velikog značaja za korišćenje staklo-poliester cevi u hemijskoj industriji. Zatezne osobine (zatezna čvrstoća i modul elastičnosti) su eksperimentalno ispitivane na isečenim uzorcima; ravni uzorci u udužnom pravcu, a uzorci u obliku prstena u obimnom pravcu. Ispitivanje je prvo izvođeno na uzorcima koji nisu bili izloženi uticaju rastvora baza da bi se došlo do saznanja o prvobitnim zateznim svojstvima ispitivanih kompozitnih materijala. Nakon toga, uzorci su stavljeni u rastvore baza natrijum-hidroksida (jaka baza, pH=14) i amonijum hidroksida (slaba baza, pH=12) 3, 10, 30 i 60 dana na sobnoj temperaturi. Nakon toga su ispitivani na zatezanje prema standardnoj proceduri. Poređenje dobijenih rezultata je izvedeno na osnovu rN vrednosti rastvora i broja dana izlaganja rastvorima baza, a na osnovu originalnih zateznih osobina. Mikromehanička analiza se izvodila u odnosu na fotografije sa skening eloktronskog mikroskopa sa prelomnih površina čime se došlo do podataka o uticaju rastvora baza na strukturu kompozitnih cevi i modele i mehanizme koji su dovodili do promene zateznih svojstava.

Zatezne osobine (zatezna čvrstoća i modul elastičnosti) su eksperimentalno ispitivane na isečenim uzorcima; ravni uzorci u udužnom pravcu, a uzorci u obliku prstena u obimnom pravcu. Ispitivanje je prvo izvođeno na uzorcima koji nisu bili izloženi uticaju rastvora baza da bi se došlo do saznanja o prvobitnim zateznim svojstvima ispitivanih kompozitnih materijala. Nakon toga, uzorci su stavljeni u rastvore baza natrijum-hidroksida (jaka baza, pH=14) i amonijum hidroksida (slaba baza, pH=12) 3, 10, 30 i 60 dana na sobnoj temperaturi. Nakon toga su ispitivani na zatezanje prema standardnoj proceduri. Poređenje dobijenih rezultata je izvedeno na osnovu rN vrednosti rastvora i broja dana izlaganja rastvorima baza, a na osnovu originalnih zateznih osobina. Mikromehanička analiza se izvodila u odnosu na fotografije sa skening eloktronskog mikroskopa sa prelomnih površina čime se došlo do podataka o uticaju rastvora baza na strukturu kompozitnih cevi i modele i mehanizme koji su dovodili do promene zateznih svojstava.",

AB  - The experimental determination of energy of glass-polyester composite tubes static fracture is done. The tubes are of defined structure and known processes of fabrication. The aim was to determine the possibility of their usage as damping elements during impact. Two types of tubular samples with different diameters were tested until fracture under static (low speed) compressive loading. The applied forces and sample lengths were measured until complete destruction of samples. From the diagrams received directly from testing devices, certain enemy values explained in the paper were determined.

AB  - In numerous cases, metals and alloys traditionally used as structural materials in the process equipment can now be successfully replaced by nonmetallic composite materials. We study the influence of service solutions on the state of stress and tensile properties of glass-polyester pipes in the longitudinal and circumferential directions. These analyses are of great importance for the use of examined pipes in chemical industry. The pipes were produced by "Poliester" Corporation (Priboj). The influence of two solutions, methanol and ammonia, was studied. The samples were treated in solutions for three, seven and ten days. After this, the samples were subjected to tensile testing by the standard procedure. The stresses and strengths were determined both in the longitudinal direction (testing on flat test specimens) and in the circumferential direction (ring tests). The analysis of test results, according to the type of solution and the period of holding, was realized in comparison with the results obtained by testing intact pipes (not subjected to the influence of the solution). The micromechanical analysis of broken samples helped to determine the influence of the solution on the structure of composite pipes and determine the models and mechanisms responsible for the decrease in strength.

AB  - The influence of liquids on the state of stresses and tensile strengths in the longitudinal and circumferential direction of glass-polyester pipes is the subject of this paper. The pipes were manufactured in Corporation "Poliester" Priboj, and had a definite structure and known fabrication process. These analyses are of great importance for the use of glass-polyester pipes in the chemical industry. The tensile properties were tested and determined for specimens cut out of the pipes; flat specimens for the tensile properties in the longitudinal direction and ring specimens for the tensile properties in the circumferential direction. First, the tension test was performed on virgin samples (without the influence of any liquid), to obtain knowledge about the original tensile properties of the studied composite material. Subsequently, the samples were treated by water, as well as alkaline and acidic solutions: sodium hydroxide (strong alkali), ammonium hydroxide (weak alkali), phosphoric acid (weak acid) and nitric acid (strong acid). The solutions were selected because of considerable differences in their pH values. The pipe segments were exposed to each liquid for 3, 10, 30 and 60 days, at room temperature. Then the specimens cut from these segments were subjected to tension testing by the standard procedure. A comparison of the results was made based on the pH values of the aggressive media in which the examined material had been soaked, as well as based on the original tensile properties and the number of days of treatment. Micromechanical analyses of specimen breakage helped in the elucidation of the influence of the liquids on the structure of the composite pipe and enabled models and mechanisms that produced the change of strength to be proposed.

AB  - Polymer composite pipes with glass fiber reinforcement have today a wide usage in the chemical and process industries. The basic subject of this paper is the determination and distribution of stresses and strains in longitudinal and circumferentional directions of glass-polyester pipes under tension test. Also, the tension strengths in both directions are determined out. Tension test was performed on an electro-mechanical test machine on flat samples and rings obtained by cutting of pipes produced by the method 'Filament winding' with glass fibers reinforcement ±55°. Also, the micromechanical analysis on fracture surfaces was done by SEM, which provided the knowledge about models and mechanisms of fracture on applyed loading.

AB  - The subject of this paper is micromechanical analyses of the crack on glass wovenepoxy composites subjected to in-plane compression load. Identification and understanding of the first damages as micro-cracks and micro-mechanisms and their further spreading during compression loading of construction of composite material are of great importance for every special usage and life prediction. Five different structures of glass epoxy composites were tested with orientation of reinforcement 0º/90º and ±45º. The specific weights of reinforcement were 125, 170, 210, 550 and 880 g/m². The analysis of compression test results was performed on the basis of the structure. Micromechanical analyses of surface cracks of the samples was carried out by scanning electron microscopy, and the established models and mechanisms of initiation and propagation of cracks are very valuable in predicting the behavior of the real constructions subjected to compression load.

AB  - Mechanical properties of composite materials are conditioned by their structure and depend on the characteristics of structural components. In this paper is presented a numerical model by which the bending properties can be predicted on the basis of known mechanical properties of tension and pressure. Determining the relationship between these properties is justified having in mind the mechanics of fracture during bending, where the fracture takes place on the outer layer which is subjected to bending while the break ends on the layer subjected to pressure. The paper gives the values of tension, pressure and bending properties obtained by the corresponding mechanical test. A comparison of the numerical results of bending properties obtained on the basis of the model with the experimental ones, shows their satisfactory agreement. Therefore, this model can be used for some future research to predict bending properties without experiments.
AB  - Mehanička svojstva kompozitnih materijala su uslovljena njihovom strukturom i zavise od svojstava strukturnih komponenata. U ovom radu prikazan je numerički model kojim se na osnovu poznatih zateznih i pritisnih mehaničkih svojstava mogu odrediti savojna svojstva. Dovođenje u vezu ovih svojstava je opravdano imajući u vidu mehaniku loma pri savijanju, gde do loma uzorka dolazi sa strane spoljnjeg sloja koji je opterećen na zatezanje dok se lom završava na sloju opterećenom na pritisak. U radu su date i vrednosti zateznih, pritisnih i savojnih svojstava dobijene izvođenjem odgovarajućih eksperimentalnih mehaničkih ispitivanja. Poređenjem numeričkih rezultata savojnih svojstava dobijenih na osnovu modela sa eksperimentalno dobijenim rezultatima uočeno je njihovo zadovoljavajuće slaganje. Samim tim pokazano je da se ovaj model može koristiti u nekim budućim istraživanjima za približno određivanje savojnih svojstava bez izvođenja ispitivanja.

AB  - The aim of this paper is to present the influence of high and low temperatures on the impact properties glass-epoxy composites. The impact strength an is presented for four different glass-epoxy composite structures at three different temperatures, i.e., at room temperature t=20°C, at an elevated temperature t=+50°C and at a low temperature t=-50°C. Standard mechanical testing was carried out on the composite materials with specific masses of reinforcement of 210 g m-2 and 550 g m-2 and orientations 0°/90° and ±45°. Micromechanical analysis of the failure was performed in order to determine real models and mechanisms of crack and temperature influence on the impact properties. .

AB  - Pipes made of composites glass fiber/epoxy resin are predominantly used in the chemical industry, construction, infrastructure and war technique. The pipes made for this purpose are in their use exposed to static and dynamic loading. Depending on the purpose, the pipes, especially those in complex structures, can be loaded by torsion. In that case, exceeding allowed tensions can cause damages such as cracking the fibers and matrix delamination. These damages can lead to the appearance of cracks on the pipes and in many cases to complete breakage of the pipe. Because of this, it is very important to evaluate composite pipes exposed to torsion and find out in which way the construction is weakened, what actually is the main goal of this paper.
AB  - Dominantnost primene cevi izrađenih od kompozita staklena vlakna/epoksi Smola je prisutna u hemijskoj industriji, građevinarstvu, infrastrukturi i ratnoj tehnici. Cevi izrađene za ovu namenu su u eksplotaciji izložene delovanju kako statičkog tako i dinamičkog opterećenja. U zavisnosti od namene, kompozitne cevi, pogotovo u konstrukcijama složenog cevovoda, mogu biti opterećene na uvijanje. U tom slučaju prekoračenje dopuštenih napona prouzrokuje oštećenja koja se ogledaju u uvijanju i pucanju vlakana, pucanju matrice i raslojavanja (delaminacije). U zavisnosti od načina slaganja vlakana javljaju se različiti modeli oštećenja, odnosno pojave prslina. Zbog toga je vrlo važno dati ocenu ponašanja kompozitne cevi izložene uvijanju odnosno ispitivanjem i analizom na prelomnim površinama doći do zaključaka koji su modeli i mehanizmi koji se pri ovom opterećenju javljaju i kako oni utiče na slabljenje konstrukcije, što i jeste predmet i cilj ovog rada.
