AB  - Wood–plastic composites (WPCs) are some of the most common modern composite materials for interior and exterior design that combine natural waste wood properties and the molding possibility of a thermoplastic polymer binder. The addition of reinforcing elements, binding agents, pigments, and coatings, as well as changes to the microstructure and composition, can all affect the quality of WPCs for particular purposes. To improve the properties, hybrid composite panels of WPCs with 30 wt. % and 40 wt. % of wood content and reinforced with one or three metal grid layers were prepared sequentially by extrusion and hot pressure molding. The results show an average 20% higher moisture absorption for composites with higher wood content. A high impact test (HIT) revealed that the absorbed energy of deformation increased with the number of metal grid layers, regardless of the wood content, around two times for all samples before water immersion and around ten times after water absorption. Also, absorbed energy increases with raised wood content, which is most pronounced in three-metal-grid samples, from 21 J to 26 J (before swelling) and from 15 J to 24 J (after swelling). Flexural tests follow the trends observed by HIT, indicating around 65% higher strength for samples with three metal grid layers vs. samples without a metal grid before water immersion and around 80% higher strength for samples with three metal grid layers vs. samples without a grid after water absorption. The synthesis route, double reinforcing (wood and metal), applied methods of characterization, and optimization according to the obtained results provide a WPC with improved mechanical properties ready for an outdoor purpose.

AB  - Polymer-bonded magnets are a class of composite material that combines the magnetic properties of metal particles and the molding possibility of a polymeric matrix. This class of materials has shown huge potential for various applications in industry and engineering. Traditional research in this field has so far mainly focused on mechanical, electrical or magnetic properties of the composite, or on particle size and distribution. This examination of synthesized Nd-Fe-B-epoxy composite materials includes the mutual comparison of impact toughness, fatigue, and the structural, thermal, dynamic-mechanical, and magnetic behavior of materials with different content of magnetic Nd-Fe-B particles, in a wide range from 5 to 95 wt.%. This paper tests the influence of the Nd-Fe-B content on impacting the toughness of the composite material, as this relationship has not been tested before. The results show that impact toughness decreases, while magnetic properties increase, along with increasing content of Nd-Fe-B. Based on the observed trends, selected samples have been analyzed in terms of crack growth rate behavior. Analysis of the fracture surface morphology reveals the formation of a stable and homogeneous composite material. The synthesis route, the applied methods of characterization and analysis, and the comparison of the obtained results can provide a composite material with optimum properties for a specific purpose.

AB  - Polymer matrix composite materials have found application in dentistry because of good mechanical properties, aesthetic, easy processing, and possibilities of the repair. Acrylates are materials used to make and repair dentures. Reinforcements in the form of short glass or polymer fibers are added to improve the mechanical properties of dental polymers. In this study, the processing of composite material with a polymer matrix from commercial auto-polymerized acrylate Simgal, with reinforcement in the form of short poly(ethylene terephthalate) (PET) fibers was examined. Samples were processed in three series: pure Simgal, Simgal/PET 1 wt% and Simgal/PET 3 wt%. The influence of the reinforcement in the form of short PET fibers on the mechanical properties of composite materials was investigated. Strength and hardness were tested by impact testing and Vickers microhardness, and it was shown that there is an increase in absorbed energy and hardness. The modulus was reduced by the addition of PET fibers and by increasing the amount of fibers in the composite. The increase in the amount of PET fibers also resulted in a smaller loss of surface mass of the samples compared to the pure matrix by 63% and 93%, respectively. Cavitation test revealed better cavitation resistance of composites than the pure acrylate.

AB  - The focus of this doctoral dissertation is the preparation and characterization of wood-plastic composites (WPC), whereby a new method of obtaining hybrid polymer composites based on wood from solution and forming the final composite by a subsequent unconventional method of thermal processing and pressing is presented. During the workmanship of this doctoral dissertation, the possibilities of synthesis and incorporation of polyethylene teraphthalate (PET) fibers and aluminum oxide (Al2O3) particles in composite materials with a polymeric matrix based on wood were investigated. By adjusting the percentage content of PET fibers and Al2O3 particles during processing, it is possible to influence the mechanical properties of hybrid composites. Poly (methylmethacrylate) (PMMA) was used as the polymer matrix. Based on a detailed literature review, it has been concluded that there is a possibility of modifying wood fibers and polymer matrix by bonding agents (3-mercaptopropyl) trimethoxysilane (MPTMS) and 2,4-toluene diisocyanate (TDI). Also, the polymer matrix acts as a wood fiber impregnator, which is certainly due to the influence of the bonding agents and does not allow the water absorption. The combination of PMMA/wood surface modification and MPET fiber reinforcement (mixture of commercially available and recycled PET in a ratio of 1: 1) and modified Al2O3 particles (MPTMS) in a small percentage (up to 3 wt%) results in composites with advanced mechanical properties and water absorption properties and offers a new way to use recycled PET flakes, and provides the opportunity for further development of incorporation of alumina particles. In order to identify incorporated reinforcements in composites, various analyses were performed, such as scanning electron microscope (FESEM), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction analysis (XRD). These analyses have shown that fibers and particles are well dispersed during the composite processing. In addition, the resistance to moist absorption resistance of the composite was tested. Based on the obtained results, it is concluded that due to well dispersed MPET fibers and Al2O3 particles in the hybrid sample and the realized bonds between the modified particles and the sample, the water absorption was the smallest and amounted to only 1 wt%.
AB  - Fokus ove doktorske disertacije je na pripremi i karakterizaciji drvo-plastičnih kompozita (WPC), pri čemu je predstavljen nov način dobijana hibridnih polimernih kompozita na bazi drveta iz rastvora i formiranje finalnog kompozita naknadnom nekonvencionalnom metodom termičke obrade- presovanjem. U toku izrade ove doktorske disertacije istražene su mogućnosti sinteze i ugradnje različitih polietilen teraftalat (PET) vlakana i aluminijum oksid (Al2O3) čestica u kompozitne materijale sa polimernom matricom na bazi drveta. Podešavanjem procentualnog sadržaja PET vlakana i čestica Al2O3 prilikom procesiranja, moguće je uticati na mehanička svojstva hibridnih kompozita. Kao polimerna matrica korišćen je poli(metilmetakrilat) (PMMA). Na osnovu detaljnog literaturnog pregleda zaključeno je da postoji mogućnost modifikacije drvnih vlakana i polimerne matrice vezujućim agensima (3-merkaptopropil) trimetoksisilanom (MPTMS) i 2,4-toluen diizocijanatom (TDI). Takođe, polimerna matrica se ponaša kao impregnator drvenih vlakana, što je svakako posledica uticaja vezujućih agensa i ne dozvoljava apsorpciju vode. Kombinacija modifikacije površine PMMA/drvo i ojačanje u vidu MPET vlakana (mešavina komercijalno dostupnog i recikliranog PET u odnosu 1:1) i modifikovanih čestica Al2O3 (MPTMS) u malom masenom procentu (do 3 mas%) rezultuje kompozitima sa naprednim mehaničkim svojstvima i svojstima upijanja vode i nudi nov način za upotrebu recikliranih PET ljuspica, i daje mogućnost daljim razvojem inkorporiranja česticama aluminijum oksida. Sa ciljem identifikacije inkorporiranih ojačanja u kompozite, izvršene su različite analize, kao što su skenirajuća elektronska mikroskopija (FESEM), infracrvena spektroskopija sa Furijeovom transformacijom (FTIR) i rendgensko-difraktometrijska analiza (XRD). Navedene analize su pokazale da su vlakna i čestice dobro dispergovani tokom procesiranja kompozita. Pored toga, ispitana je efikasnost rezistentnosti na apsorpciju vlage kompozita. Na osnovu dobijenih rezultata zaključuje se da je zbog dobro dispergovanih MPET vlakna i čestica Al2O3 u hibridnom uzorku i ostvarenih veza između modifikovanih čestica i uzorka, apsorpcija vode najmanja i iznosila je svega 1 mas%.

AB  - Hybrid composite panels of Wood-Plastic Composites (WPC) consisting of wood and poly (methyl methacrylate) (PMMA) were reinforced with alumina particles and made by "hot pressing" method. Alumina-based particles were made by sol-gel technique. The particles were characterized by the X-ray diffraction (XRD). The resulting alumina particles were modified with (3mercaptopropyl) trimethoxysilane (MPTMS), in order to obtain better mechanical properties of the composite relative to the composite with unmodified alumina particles. The aim of this work was to study the influence of composite structure and the moisture absorption on bending and the impact properties of the hybrid composite. The bending and impact tests revealed that modulus of elasticity and absorbed energy of deformation increased with modification of alumina and slightly decrease after moisture absorption.

AB  - Antibiotic containing polycaprolactone (PCL) fibers were produced by using three electrospinning methods: blend, emulsion and co-axial electrospinning (labeled as S1, S2 and S3, respectively). The profiles of drug release from three different systems were studied and antimicrobial properties of produced materials were evaluated. Morphology of the produced fibers was characterized and revealed that cefazolin-loaded PCL fibers had smaller diameter compared to neat PCL fibers, while the chemical interaction between the antibiotic and PCL showed that cefazolin neither had reacted with PCL phase, nor had degraded during the electrospinning process. The crystallinity and thermal characterization of fabricated fibers showed that the addition of cefazolin decreased the crystallinity of PCL. The results of the drug release behavior of the blend and co-axial electrospun fibers was on a higher level (similar to 68% and similar to 43%, respectively) compared to the emulsion electrospun fibers (similar to 5%), after a period of 30 days. The obtained data had the best fitting with the first order model and the Higuchi model, while the Korsmeyer-Peppas model showed a Pseudo-Fickian diffusion of the drug. Antibacterial evaluations showed that cefazolin-loaded PCL fibers had better effects on Staphylococcus aureus compared to Escherichia coll. during the treatment period and that the effect of the emulsion fibers was notably weaker than the other two studied systems. The aim of the study was to test different systems for control drug release of different dynamics, which will be applied for prevent bacterial accumulation when indwelling urinary catheters, applied for different periods of time.

AB  - During the last two decades, interest in bio-based polymers, especially in bio-based composite materials, has grown as a result of environmental concerns. In this paper new composites obtained from fully bio-based unsaturated polyester resin (UPR) and waste poly(ethylene terephthalate) (PET) were studied for the first time. The composites were prepared by crosslinking the UPR in the presence of functionalized PET particles (3, 6 and 9 wt %), using dimethyl itaconate as reactive diluent. The results showed that the incorporation of the PET particles led to the increase in mechanical properties. However, higher PET loading caused a decrease in the mechanical properties of the composites because of the PET particle agglomeration.

AB  - Poly(ethylene terephthalate) (PET) fibers (virgin, waste, and mixed) were incorporated in the composite poly(methyl methacrylate) (PMMA)-wood. Hybrid composite panels were prepared by pressure molding. Toluene-2,4-diisocyanate (TDI) and (3-mercaptopropyl)trimethoxysilane (MPTMS) were used as cross-linking bonding agents for modification of wood fibers. Influence of cross-linking bonding agents, structure, and composition of PET fibers was examined by studying thermomechanical properties as well as moisture absorption. Moisture absorption was lower for composites with bonding agents. Mechanical testing revealed that the addition of PET fibers drastically enhances properties of the composites. Covalent and hydrogen bonds formed with the addition of bonding agents have also improved mechanical properties compared to the untreated composites.

AB  - The Nd-Fe-B-barium ferrite hybrid composite materials with epoxy matrix presented in this paper cover maximum energy product from 1 to 13 MGOe. Mixture of magnetic particles is responsible for high magnetic quality, while the thermosetting resin plays a role in mechanical properties.

AB  - In this paper, the impact of wood fiber surface modification on mechanical properties of poly-(methyl methacrylate)(PMMA)-wood composite was examined. FTIR analysis has shown that the wood fiber surface modification was accomplished and that the matrix-fiber bond was established. The SEM image of the breakage surface has affirmed the improved adhesion between the fibers and the polymer in the specimen with modified wood fibers. The bond improvement between the wood fibers and the matrix results in increased hardness and a better distribution of strain within the composite. High speed impact testing results have shown that the specimen with the bonding agent can increase the absorbed energy six times when compared to the pure PMMA specimen.
