Abstract:

Abstract Marloeke van der Vlugt creëert sculpturale en ruimtelijke installaties die het publiek uitnodigen om te interacteren met lichamen, organismen, objecten en materialen op een niet-hiërarchische manier. Haar doel is om het bewustzijn van de wederkerige aard van ons in-de-wereld-zijn te vergroten. Ze deelt de visie van filosofe Jane Bennett wanneer die stelt dat alle materialiteiten een eigen vorm van agency en een dynamische relatie met hun omgeving hebben. Om dit open wereldbeeld te kunnen ervaren, gunnen haar installaties het publiek of de participanten de tijd en ruimte om events te verkennen, die ontstaan door de wederzijdse relatie tussen hun eigen lichaam en de andere materialiteiten. Ze maakt gebruik van strategieën zoals multisensoriële activering, ruimtelijke vormgeving of gegidste rondleiding, om het publiek of de participanten gevoelig te maken voor een wereld die bevolkt wordt door actieve, veranderlijke voorwerpen in plaats van passieve objecten.

Abstract:

Glass–ceramic composite materials are being investigated for numerous applications (i.e., textile, energy storage, nuclear waste immobilization applications, etc.) due to the chemical durability and flexibility of these materials. Borosilicate and Fe–Al–borosilicate glass–ceramic composites containing brannerite (CeTi2O6) or zirconolite (CaZrTi2O7) crystallites were synthesized at different annealing temperatures. The objective of this study was to understand the interaction of brannerite or zirconolite-type crystallites within the glass matrix and to investigate how the local structure of these composite materials changed with changing synthesis conditions. Powder X-ray diffraction (XRD) and Backscattered electron (BSE) microprobe images have been used to study how the ceramic crystallites dispersed in the glass matrix. X-ray absorption near edge spectroscopy (XANES) spectra were also collected from all glass–ceramic composite materials. Examination of Ti K-, Ce L3-, Zr K-, Si L2,3-, Fe K-, and Al L2,3-edge XANES spectra from the glass–ceramic composites have shown that the annealing temperature, glass composition, and the loading of the ceramic crystallites in the glass matrix can affect the local environment of the glass–ceramic composite materials. A comparison of the glass–ceramic composites containing brannerite or zirconolite crystallites has shown that similar changes in the long range and local structure of these composite materials occur when the synthesis conditions to form these materials or the composition are changed.

Abstract:

We report the manufacturing and characterization of poly (butylene succinate) (PBS) and micro cellulose (MCC) woody-like composites. These composites can be applied as a sustainable woody-like composite alternative to conventional fossil polymer-based wood-plastic composites (WPC). The PBS/MCC composites were prepared by using a melt blending of 70 wt% of MCC processed from bleached softwood. MCC was modified to enhance dispersion and compatibility by way of carbodiimide (CDI), polyhydroxy amides (PHA), alkyl ester (EST), (3-Aminopropyl) trimethoxysilane (APTMS), maleic acid anhydride (MAH), and polymeric diphenylmethane diisocyanate (PMDI). The addition of filler into PBS led to a 4.5-fold improvement of Young’s modulus E for the MCC composite, in comparison to neat PBS. The 1.6-fold increase of E was obtained for CDI modified composition in comparison to the unmodified MCC composite. At room temperature, the storage modulus E′ was found to improve by almost 4-fold for the APTMS composite. The EST composite showed a pronounced enhancement in viscoelasticity properties due to the introduction of flexible long alkyl chains in comparison to other compositions. The glass transition temperature was directly affected by the composition and its value was −15 °C for PBS, −30 °C for EST, and −10 °C for MAH composites. FTIR indicated the generation of strong bonding between the polymer and cellulose components in the composite. Scanning electron microscopy analysis evidenced the agglomeration of the MCC in the PBS/MCC composites. PMDI, APTMS, and CDI composites were characterized by the uniform dispersion of MCC particles and a decrease of polymer crystallinity. MCC chemical modification induced the enhancement of the thermal stability of MCC composites.

Abstract:

Fillers or reinforcing components are an integral part of composite materials. A classification of composites according to structural features and fineness has been adopted. Ideas about the effect of fillers on the physical, mechanical and operational characteristics of composite materials and products have been defined and are constantly being deepened. In this regard, the use of volcanic rocks as fillers is noteworthy. The prospects for the use of certain types of volcanic rocks as disperse fillers of polymer composites are justified by their significant distribution and accumulation of fine fractions of screenings as waste during their extraction and processing. At the same time, the achievement of the effectiveness of such raw materials requires a deepening of ideas about the composition and physico-chemical properties, in the direction of which this work has been done. Physical and chemical studies in terms of evaluating the suitability of volcanic rocks (perlite, zeolite, andesite) as ingredients of polymer composite materials made it possible to obtain quantitative data on their chemical and mineralogical composition, hydrophilic-lyophilic balance and energy state of their surface. The interpretation of the obtained results concerning the potential interaction of the studied materials with polymeric binders is given taking into account the above features of their composition, structure and quantitative IR spectroscopy data in terms of structure-forming bonds Si–O–Si, S –O–Al, hydroxyl groups and adsorbed water. These features indicate the possibility of choosing volcanic rocks as fillers for polymer composites with the required lyophilic-lyophobic balance and energy state of their surface and providing an unlimited level of interaction with polymer binders as a factor in shaping the structure and properties of composites.

Abstract:

Technological developments and the influence of globalization have an impact on increasing the need for the amount of material for industry. The many disadvantages of metal materials due to their large mass, difficult manufacturing processes, corrosive properties, and high production costs have resulted in reduced use of metal materials in various products. Nowadays, there are many replacement materials with mechanical properties that can resemble metal materials such as composites. The role of composites is very important in the development of today's industrial world. This study wanted to determine the effect of the composite composition of rias banana fiber and teak sawdust with epoxy resin on the mechanical properties of the composite. The results showed that the comparison of the composition of the composite using rias banana fiber and teak sawdust with an epoxy matrix had an effect on the mechanical properties. Increasing the percentage of resin composition increases the value of the surface hardness of the composite. The highest level of Rockwell hardness with a value of 117 HRB in sample D and the lowest 109 HRB in sample A. While the highest max strength value was produced by sample C with a composition of teak sawdust: rias banana fiber: epoxy is 20% : 40% : 40 %. The conclusion of this research is the more resin composition will increase the composite hardness test value.

Abstract:

Rapid expansion of technologies poses higher requirements to structural materials and items made of them. Conventional materials are being replaced by composite materials (composites). Different additives enhancing the properties of initial materials are used as reinforcement fibers of composites. Utilization of micro-and nanosize particles for production of present-day materials is paid much attention to. Whiskers are among such materials. These crystals have high strength, high chemical and temperature resistance. But for rational utilization of whickers of different chemical composition in composite materials one should know their physical and chemical properties. Objectives of the paper: to study physical and chemical properties of whiskers in different compounds, their composition and structure; to prove experimentally the feasibility of utilizing whiskers as a reinforcement fiber of composite materials. Object of study: specimens of whiskers of silicon nitride (Si3N4), aluminum oxide (Al2O3), aluminum nitride (AlN), and mullite (Al6Si2O13). Methods of investigation: thermal study of specimens, study of mechanical properties and chemical strength, and IR-spectroscopy. Results of study: specimens of whiskers have been studied and their mechanical properties have been tabulated for comparison. Extensive thermal investigation was followed by deduction of regularities and identification of chemical properties of whiskers. IR-spectra of whiskers have been studied and conclusions on molecular composition and on presence of impurities in some whiskers have been made.

Abstract:

Abstract Carbon nanotubes because of their high mechanical, optical or electrical properties, have found use as semiconducting materials constituting the reinforcing phase in composite materials. The paper presents the results of the studies on the mechanical properties of polymer composites reinforced with carbon nanotubes (CNT). Three-point bending tests were carried out on the composites. The density of each obtained composite was determined as well as the surface roughness and the resistivity at room temperature. Moreover the surface studies on an atomic forces microscope (AFM) and X-ray studies (phase composition analysis, crystallite sizes determination) were carried out on such composites. Measurements of the surface topography using the Tapping Mode method were performed, acquiring the data on the height and on the phase imaging. The change of intensity, of crystallite size and of half-value width of main reflections originating from carbon for composites have been determined using the X-ray analysis. Carbon nanotubes constituting the reinforcement for a polymer composite improve the mechanical properties and con-ductivity of the composite.

Abstract:

The novelty of this work consists of obtaining original fundamental data on the laws of synthesis of new metal matrix composite materials for additive technologies. CrN + TiNi composites were obtained using the method of self-propagating high-temperature synthesis. In this work, analysis of the parameters of the synthesis of composite materials as well as their structure and phase composition were carried out. A scheme for the formation of a composite structure is established; it is shown that the phase composition is represented by 54.6 wt.% CrN and 45.4 wt.% TiNi. It was shown that composites based on the system are suitable for machines that make use of direct laser deposition to grow layers of materials. Sample structure and phase parameters were studied. It is shown that titanium nitride particles are uniformly distributed in the CrNi intermetallic matrix, the TiN particle size ranges from 0.3 to 9 μm and the average particle size is 2.8 μm. The results obtained indicate the possibility of synthesizing promising metal matrix composite materials for additive technologies. Such materials may have increased hardness, operating temperature and strength.

Abstract:

The fillers from agriculture and industrial wastes filled natural rubber (NR) have been prepared to clarify their properties and develop to be the eco-friendly composites. This research aims to study the composites namely rice husk ash (RHA)/NR, clay/NR and crumb rubber/NR composites on the curing characteristics, mechanical and morphological properties. The results indicated that depending on a chemical composition of fillers, the properties of the composites are varied. For clay/NR composite, the occurrence of vulcanization was delayed comparing to the others. In term of mechanical properties, crumb/NR composite shows a toughest characteristic, for examples, it has the highest tensile strength, elongation at break and tear resistance, whereas hysteresis loss was found to be lowest among the composites. The toughness of crumb/NR composite can be influenced by a better interfacial interaction between filler and matrix comparing to the others as revealed by SEM. The clay/NR composite, on the other hand, has the highest hardness among the composites due to the hardness of clay itself and its uniformity of particle size. In the case of RHA/NR composite, from morphological observation by SEM shows that RHA particles have very poor dispersion in NR matrix which resulted in poor mechanical properties. However, the presence of RHA agglomerates was found to be beneficial for loading a high stress under a small deformation, for example, at 25% elongation. Therefore, these three difference composites from wasted materials were found to have unique characteristics which can be chosen and applied for some specific applications.

Abstract:

Powders of copper, zinc, manganese-substituted tricalcium phosphates (TCP) were synthesized, the composition and structure of the obtained compounds were studied. It is shown how copper, zinc and manganese ions affect the phase composition and microstructure of powders substituted with TCP. Composite materials based on a blend of polyvinylpyrrolidone with alginate (PVP:ALG) containing copper, zinc, and manganese-substituted TCP have been obtained. The thermal stability and mechanical strength of composite films crosslinked with polyvalent metal ions have been studied. The least strong, but at the same time more thermally stable composites crosslinked with alkaline earth metal ions. The test for cytotoxicity of powders substituted TCP’ extracts and composites showed that the powders and composite materials with them are non-toxic and biocompatible. The study of the antibacterial activity of the materials against the Escherichia coli C600 strain showed that the growth of bacteria was inhibited by the samples containing copper-TCP and zinc-TCP. The composite with manganese-TCP showed no activity against Escherichia coli C600. Composites based on the PVP:ALG blend with copper, zinc-substituted TCP can be considered as materials with an antibacterial effect for use in medicine.

Abstract:

The concept of functionally graded materials (FGMs) was originated in the research field of thermal barrier coatings. Continuous changes in the composition, grain size, porosity, etc., of these materials result in gradients in such properties as mechanical strength and thermal conductivity. In recent years, functionally graded structural composite materials have received increased attention as promising candidate materials to exhibit better mechanical and functional properties than homogeneous materials or simple composite materials. Therefore the research area of FGMs has been expending in the development of various structural and functional materials, such as cutting tools, photonic crystals, dielectric and piezoelectric ceramics, thermoelectric semiconductors, and biomaterials. We have developed functionally graded structural ceramic/metal composite materials for relaxation of thermal stress, functionally graded anti-oxidation coatings for carbon/carbon composites, and functionally graded dielectric ceramic composites to develop advanced dielectric ceramics with flat characteristics of dielectric constant in a wide temperature range. This paper introduces functionally graded coatings for C/C composites with superior oxidation resistance at high temperatures.

Abstract:

Rubber seed shell (RSS) and Palm Oil Fronds (POF) are types of solid waste produced from rubber and palm oil plantation that has not been fully utilized. Meanwhile, in the automotive industry, composites have been the material of choice in some of its components. For example, composite body panels have been widely used in sports cars and passenger cars. This study aimed to utilize RSS powder and POF fiber waste as reinforcing fillers for the composite matrix. The matrix used was liquid polyester resin with the addition of catalyst as a hardener. RSS, which has been carbonized, was then activated using H2SO4 while POF fiber was pre-treated with 5% NaOH, then characterized both fillers by FTIR and SEM. Composites filled by RSS and POF in 4 variations were tested for mechanical properties with matrix composites without fillers as controls. FTIR testing of RSS carbonized powder found that carbonyl group consisting of tar compounds and remnants of carbon dioxide compounds that lost after activation with the H2SO4 solution. Meanwhile in POF fibers found that carbonyl group consisted of lignin and hemicellulose disappear after pre-treatment by 5% NaOH. SEM testing of RSS and POF fillers showed changes in surface morphology. The RSS and POF surface became coarser and porous, and the fibrils of POF fiber more obvious. The mechanical properties showed that the optimum result obtained in the composition of Matrix/POF/RSS (92.5/2.5/5).

Abstract:

Translucence parameters for 3 series of experimental hybrid composites were investigated using three-chromatic coordinates such as L* a* b* CHROMA technique using a type C illuminant geometry with the scope of 8o. The materials of each series contain in the same ratio different copolymers and a filler mixture (simple and mixed hydroxyapatite-ZrO2 or SiO2 powders and glass powders with barium oxide, respective strontium oxide, or quartz powder). The purpose was to determine the effect of filler composition of composites on translucence. The analysis shows that these materials have more or less translucence. CHROMA determinations indicate that for the composite that has as filler quartz microparticles anh hydroxyapatite nanoparticles, the translucence registered is higher. Results leading to the idea that chemical composition and the size of inorganic phase are important to obtain translucent composite materials that have very natural in appearance. Keywords: translucence, hybrid composites, CHROMA method.

Abstract:

<h1>In general, household waste water pipelines use plastic pipes of PVC type that are not environmentally friendly and are relatively expensive. Therefore, this research will design molds and manufacture of composite pipes using raw materials of clampshell powder. The raw material used is clampshell powder with the composition of MgO and CaO compounds which is about 22.28% and 66.70%. The mixture of materials used consisted of clampshell powder with a size of 40 mesh, catalyst, and unsaturated polyester resin as a matrix. The objective of this study is manufacture of water pipes made from polymer composites reinforced by clampshell powder. Composite pipe manufacturing is carried out using the casting method. Pipe molds are made of stainless steel with a diameter of 40.46 mm (1.6 in) and an outer diameter of 50.8 mm (2 in). This mold size follows SNI 06-0084-2002 standards. The results of the study, water pipes from polymer composite material reinforced by clampshell powder with an inner diameter size of 40.64 mm and varying outside diameter. This variation depends on the composition of the clampshell powder in composite materials. The greater the clampshell powder composition, the more easily the maximum pipe wall thickness can be obtained. The average wall thickness variation is 3.35 mm. This variation is still included in the polymer water pipe requirements, which is a minimum of 2 mm.</h1>

Abstract:

The review of the works on the fabrication-technology studies, patterns of structure formation, and properties of in situ composites is presented. The main advantage of in situ (natural) composites is the thermodynamic stability of their composition and the coherence (conjugation) of the lattices of the contacting phases. All these ones provide the composite with a high level of the physical and mechanical properties. As shown, composite materials of this type are formed in the process of directed phase transformations, such as eutectic crystallization, eutectoid decomposition, etc., caused by a temperature gradient, as well as a result of diffusional changes in composition. The conditions for the growth of in situ composites are formulated. The mechanisms of growth of composite structures of the eutectic type are considered. The factors influencing on the morphology of structures of the eutectic type are indicated. The considered technological methods make it possible to obtain materials with predetermined properties, in which the size, volumetric composition, and spatial arrangement of phases are characteristic of in situ composites. The paper provides a large number of examples of in situ composites: from low-melting Bi-based alloys to refractory eutectics based on Mo and W (Bi–MnBi, Cd–Zn, Al–Al3Ni, Al–Al4La, Al–Al10CaFe2, Al–Al9FeNi, Al–Al3Zr, Al–Al3Sc, Au–Co, Si–TaSi2, Cr–HfC, Cr–ZrC, Cr–NbC, Cr–NbC, Cr–TaC, Nb–Nb5Si3, Mo–ZrC, Mo–HfC, W–TiC, W–ZrC, W–HfC, etc.). Processes and aspects of structure formation are considered. The influence of additional doping on the structure and properties of composite materials of the eutectic type of binary systems, as well as the features of the structure formation of ternary colonies in the composite are considered.

Abstract:

Composite materials have a wide range of functional properties, which is ensured by using various technological methods of obtaining both the matrix or fillers and the composition as a whole. A special place belongs to the composition formation technology, which ensures the necessary structure and properties of the composite. In this work, a computer simulation was carried out to identify the main dependencies of the behavior of composite materials in the process of the main technological operations of their production: pressing and subsequent sintering. A polymer matrix randomly reinforced with two types of fillers: spherical and short cylindrical inclusions, was used to construct the finite element models of the structure of composites. The ANSYS Workbench package was used as a calculation simulation platform. The true stress–strain curves for tension, Poisson’s ratios, and ultimate stresses for composite materials were obtained using the finite element method based on the micromechanical approach at the first stage. These values were calculated based on the stretching diagrams of the matrix and fillers and the condition of the ideality of their joint operation. At the second stage, the processes of mechanical pressing of composite materials were modelled based on their elastic–plastic characteristics from the first stage. The result is an assessment of the accumulation of residual strains at the stage before sintering. The degree of increase in total strain capability of composite materials after sintering was shown.

Abstract:

The specific operating conditions of products made of thermoplastic materials necessitate targeted modification of polymer binders, which reduces the characteristic disadvantages of thermoplastics and enhances their advantages .The article examines some aspects of the use of composite materials based on thermoplastics. The most effective modifiers of polymer matrices, from the point of view of increasing their parameters of deformation-strength and tribotechnical characteristics, are components that prevent the development of thermo -oxidative destruction and tribocracking processes. In our opinion, the formed requirements for functional composite materials based on thermoplastics can be ensured by implementing the basic methodological principles, which consist in increasing the resistance to the effects of thermo oxidizing and operating environments and aging.

Abstract:

Composite systems composed of nanocrystalline apatites and oligolactide-based polymer networks were prepared resulting in malleable and even injectable formulations which can be cured to compact materials at body temperature. Porous devices with inter-connective porosity were obtained after addition of suitable foaming agents to the composite mixtures. Setting time, porosity and mechanical properties of the composites can be properly adjusted by varying the educt composition. The determined compressive strengths and Young’s moduli of the porous composites perfectly match the mechanical characteristics of cancellous bone material. Preliminary in vitro cell culture experiments with compact composite materials demonstrated their good cytocompatibility. Based on these findings, the synthesized nano-structured composites represent promising candidates for the development of new biomaterials usable in hard tissue regeneration.

Abstract:

Development of new composite materials is the worldwide extremely progressive branch of engineering activity. Composite materials are applied in many industries. The principle of composite materials is a combination of different materials providing an entirely new material with specific properties. Fiber-reinforced composites rank to the most frequently used composites because of their suitable mechanical properties. There were studied mechanical properties of fibre reinforced cementitious composites (FRCC) exposed to high temperatures of 600 °C and 1000 °C in the paper. For the production of refractory FRCC were used aluminous cement Secar®71 with 70 % of Al2O3. Various composites differed in the used type of fibers - basalt, carbon and ceramic fibres were applied in doses of 2 % by volume. For the experimental program were prepared prismatic specimens with the total dimensions of 40 × 40 × 160 mm3 and cured for 28 days in humid environment. Residual bulk density, flexural and compressive strength were investigated in the performed experimental program. The results showed the positive effect of the fibers used in refractory composition and the dependence on the length of the used fibers.

Abstract:

Composite materials (also called composition materials or shortened to composites) are materials made from two or more constituent materials with significantly different physical or chemical properties, that when combined, produce a material with characteristics different from the individual components. The individual components remain separate and distinct within the finished structure. The new material may be preferred for many reasons: common examples include materials which are stronger, lighter or less expensive when compared to traditional materials. Composite materials are generally used for buildings, bridges and structures. The most advanced examples perform routinely on spacecraft in demanding environments.

Abstract:

Two materials with potential application in bone tissue repair have been developed: 1) a non-biodegradable composite based in a new methacrylic-co-acrylic matrix; and 2) a biodegradable composite based in a chitosan (Ch) matrix. Both matrices were reinforced with glass-ceramic particles of composition (mol%) 70 SiO2 – 30 CaO. The in vitro bioactivity of composites was assessed by soaking in simulated body fluid (SBF) for periods of up to 7 days at 37º C. X-ray diffraction (XRD) and scanning electron microscopy coupled with X-ray energy dispersive spectroscopy (SEM-EDS) were used for deposit identification after different soaking periods. Calcium phosphate particulate deposits were detected after 3 days of immersion, followed by growth and maturation towards apatite.

Abstract:

The article presents the results of a study of the synthesis of composite materials based on coal waste combined with coal and polymer raw materials, using ultrasonic chemistry methods and determining the possibility of their use as an active mineral additive for replacing part of cement in fine-grained concrete. By varying the composition of the matrix and the filler, a composite material is obtained whose properties are quantitatively and qualitatively different from the properties of each of its components. As a filler in the composition of the composite material, burned rock is used - the product of oxidative self-firing of waste rock, extracted together with coal to the surface. Burned rocks contain an organic part (unburned carbonaceous impurities) and a mineral part (calcined clay-sandy part). Features of the material composition of burned rocks, coal industry waste allows us to consider them as secondary mineral raw materials. The binder in the composite material used is thiourea-formaldehyde resin. The resin was obtained by the standard method of polycondensation of thiourea with formaldehyde at a molar ratio of thiocarbamide:formaldehyde = 1:2. The choice of thiourea-formaldehyde resin is due to the availability, water solubility and the presence of a sufficient number of proton acceptor centers capable of complexation with a modifier. The modifier for composite materials used a coal waste product related to promising natural polymers in nanotechnology, sodium humate, extracted by alkaline extraction from oxidized coal from the Shubarkol deposit. Sodium humate refers to polyfunctional polymers with a unique combination of hydrophobic and hydrophilic sites, a variety of oxygen-containing functional groups, aromatic, heterocyclic and other groups. All this suggests a high ability of sodium humate to intermacromolecular interactions with both the burned rock and thiourea-formaldehyde resin. Composite material based on burned rock, sodium humate with thiourea-formaldehyde resin was synthesized by impregnation using ultrasonic treatment. The decisive role of ultrasonic activation is shown and the effectiveness of its application to the process of producing composites is noted. The modern physicochemical and physicomechanical methods have characterized the composition and structure of the obtained composite materials. The mineralogical composition of composite materials was studied using x-ray phase analysis, and surface morphology based on microscopic analysis using a scanning electron microscope. Filling the composite material with burnt rock provides higher physical and mechanical properties. The strength of burnt-filled composites is higher than that of samples of a similar composition without burnt rock. The resulting composite can be used as a building material. Key words: composite material, filler, binder, burned rock, thiourea-formaldehyde resin.

Abstract:

Although most materials contain more than one phase, and thus are multiphase materials, the definition of composite materials is commonly used to describe those materials containing more than one phase deliberately added to obtain certain desired physical properties. Composite materials are often classified according to their application, i.e. structural composites and electronic composites, but may also be classified according to the type of compounds making up the composite, i.e. metal/ceramic, ceramic/ceramie and metal/semiconductor composites. For structural composites it is also common to refer to the type of structural reinforcement; whisker-reinforced, fiber-reinforced, or particulate reinforced composites [1-4].For all types of composite materials, it is of fundamental importance to understand the relationship between the microstructure and the observed physical properties, and it is therefore vital to properly characterize the microstructure. The interfaces separating the different phases comprising the composite are of particular interest to understand. In structural composites the interface is often the weakest part, where fracture will nucleate, and in electronic composites structural defects at or near the interface will affect the critical electronic properties.

In the creation of new polymeric composite materials, the use of biologically active substances, e.g. the hydrolysis products of keratin-containing proteins of different structure, is promising. The possibility of using keratin hydrolysates as modifying additives for improving different properties of various elastomer composites is shown. These are vulcanising agents and vulcanisation accelerators for composite materials based on synthetic polyisoprene; secondary vulcanising agents for elastomer materials based on chlorine-containing rubbers; vulcanisation accelerators for composites. The use of these compounds makes it possible to remove from the composition of materials ecologically harmful components and ingredients that are produced from non-renewable sources of raw material, to solve a number of economic problems, associated, among other things, with the need for import replacement, and also to produce latex composites that in their properties approach latexes of natural rubber.

To address the issues of poor thermal conductivity and fragmentation of metal hydride particles undergoing hydriding/dehydriding reactions, a metal hydride-based composite material was developed. The active metal phase was embedded in a silica matrix and a graphite filler was incorporated by ball milling. A set of compact pellet samples at different composition were prepared and tested. Experimental data obtained from the thermal conductivity measurements shown that using powder graphite produced a quite linear increase in the thermal conductivity of the metal hydride – silica composite. Ongoing studies include composition optimization as well as long-term testing upon cycling of such metal hydride composites to evaluate their potentiality in technological hydrogen storage applications.

The development of surgery in the field of bone tissue reconstruction provides a stable demand for new materials for implants. Of particular interest are materials based on hydroxyapatite, which are close in chemical composition to the elemental composition and structure of bone and have similar biologically active properties. In this work, the regularities of the formation of new composite materials based on a zinc-modified hydroxyapatite framework coated with a copolymer of lactide and glycolide were revealed for the first time. The aim of this work was to obtain porous composite materials based on zinc-modified hydroxyapatite and a copolymer of lactide and glycolide with properties suitable for use as a material for bone implants. The phase and elemental composition of the composites was studied by infrared spectroscopy, X-ray diffraction, and X-ray spectral microanalysis. Regularities have been established between the surface properties and the composition of materials, as well as their biocompatibility, determined using monocytes isolated from human peripheral blood. The antibacterial activity of the materials against gram-positive and gram-negative bacteria was determined.

Abstract:

ABSTRACT Introduction. The question of a comparative assessment of the quality of images obtained as a result of scanning test composite materials exposed under the cyclic effects of positive and negative temperatures is considered. The samples are sorted relative to the reference numerical metric expressed as a percentage. Materials and methods. The compared composites differ in composition relative to the control sample. Periodic scanning of the tested composites is carried out during several control points of time. A comparative analysis of the image quality of test composites was carried out both during the entire exposure time and at the control points of time. On the basis of the existing algorithm Structural Similarity Index for measuring image quality (SSIM), percentage indicators of sample quality were determined depending on the composition and exposure time. The results obtained allow the selection of composite materials in accordance with the level of structural similarity in structural color characteristics. According to the SSIM algorithm, the resulting metric values are in the range [-1; +1]. Full structural similarity corresponds to a value equal to one. It is proposed to express the SSIM metric as a percentage with the transformation that the change in the color structural difference of the relative control sample can vary from zero to 100 %. Results. For the proposed method of comparing images of scanned samples of composite materials, ten samples of composite materials of different composition were used. Numerical results of the experiment with their graphical visualization give a clear idea of the nature of the change in color characteristics relative to the control sample. Consistent evaluation at the exposure points shows the nature of changes in the properties of materials from the duration of exposure to cyclic changes in positive and negative temperatures. Conclusions. The proposed benchmark image quality assessment based on the existing SSIM algorithm allows you to quickly investigate groups of materials, the change in properties of which is caused by their exposure in adverse operating conditions.

Abstract: Manganese zinc ferrite/barium ferrite composite materials were prepared with various content of Z type barium ferrite (0, 10, 20 wt%) using solid state reaction method. The effect of the compositon on the microstructure and electromagnetic properties of the composites are investigated by means of X-ray diffraction, scanning electron microscope and impedance analyzer. The X-ray diffraction patterns reveal that W phase of barium ferrite instead of Z phase appears in the composite sintered as well as the spinel phase. Some small hexagonal grains were observed in the SEM images and the proportion increases with increasing content of barium ferrite. The cut-off frequencies of the composite systematically shift towards high frequency from 2.5 MHz to 32.6 MHz which is attributed to the increasing of W phase. The composites show a higher frequency for the maximum of the impedance as well as a higher value of the impedance at certain frequency which may be benefit for the application at GHz frequency range.

Dental composite restorative materials consist of an organic matrix, ceramic fillers, and the interface between the inorganic fillers and the matrix. Marked variations in the composition of the composite materials, as well as different degrees of conversion after polymerization, have been observed. These circumstances lead to substantial differences in the properties of polymerized composite materials. The variations in clinical behavior of the different composite materials, e.g., discoloration or lack of wear resistance, may be explained on the basis of differences in composition.
