COMMERCIAL SILICONE RESIN (review). Part 1

The analysis of literary and patent sources, advertising booklets of domestic and foreign companies on the properties and methods of production of commercial silicone resins has been carried out. The main types of classification of commercial silicone resins are outlined and structural factors are described: the type of organic radicals (R), R/S ratio, SiO_х content, Ph/Me ratio and molecular weight. A brief overview is given in the field of market analysis of commercial silicone resins and the scope of products based on them. Practically significant methods of MQ-resins production are described, the latest insights into their structure and properties are shown.

SYNTHESIS AND STUDY OF THE PROPERTIES OF YTTRIUM OXIDE SOLS

Sols of yttrium oxide with a Y₂O₃ content of 1, 5, and 10 wt. % have been synthesized. The structure and properties of sols have been studied: particle size and morphology, ζ-potential. According to the results of the study by photon correlation spectroscopy, the distribution of particle sizes in sols was determined: the average particle size was 49.3 nm for a sol with a Y₂O₃ content of 1 wt. %, 67 nm for a sol with a Y₂O₃ content of 5 wt. % and 232 nm for a sol with a Y₂O₃ content 10 wt. %. According to the results of XRD studies, the average size of crystallites of yttrium oxide nanopowder was 38.5 nm, which correlates with the results of the TEM study – 30–50 nm. The ζ-potential of the sols decreases with an increase in the concentration of yttrium oxide from –0.14 mV to –3.21 mV, however, it is quite small and indicates a low aggregative stability of the sols.

CALCULATION OF THE TEMPERATURE DEPENDENCE OF THE MAGNETIZATION OF SINTERED MATERIALS Pr–Dy–Fe–Co–B USING MOLECULAR FIELD APPROXIMATION THEORY

Provides a theoretical calculation of the magnetization of sintered materials Pr–Dy–Fe–Co–B and provides quantitative estimates of the dependence of magnetization on the concentration of dysprosium and cobalt. The optimal concentrations of these elements have been established, leading to the minimization of the temperature coefficient of induction. Experimental data on the dependence of magnetization on temperature are obtained. Experimental and theoretical dependences agree well with each other. This indicates the presence of predictive capabilities of the developed calculation model and allows us to hope for such a selection of concentrations of chemical elements that would make the magnetic properties of ring magnets in gyroscopes insensitive to temperature in the required operating range.

INFLUENCE OF WEFT THREAD DEFLECTION IN REINFORCING FILLER ON ELASTIC-STRENGTH PROPERTIES OF PCM

Currently for the manufacture of prepregs a huge number of reinforcing fillers are produced. All fillers are subject to certain technical requirements, including appearance however there is no requirement for the angle of deflection of the weft thread relative to the warp of the fabric. In the framework of this work, the reasons for the deviation of the weft thread relative to the warp of the fabric, which lead to the formation of defective zones on the prepreg, are considered. The angle of deflection of the weft thread was measured. The effect of weft thread deflection on the final elastic-strength properties of a polymer composite material has been studied.

INFLUENCE OF THERMOCYCLIC EFFECTS ON THE PROPERTIES OF FIBERGLASS

The article is devoted to the study of the influence of thermocyclic effects and operating temperature on the properties of polymer composite materials based on the fiberglass and epoxy binder. It is established that the «heating–cooling» cycles for fiberglass with different polymer matrix content and reinforcement options cause some decreases in strength and elastic dynamic characteristics, but this does not adversely affect the operation of protective screens or engine nacelles for gas turbine engines made of fiberglass.

SPHEROIDIZATION OF POWDER COMPOSITIONS BASED ON REFRACTORY METALS (review). Part 2

The second part of the article presents a review of scientific and technical literature in the field of spheroidization of powder compositions based on tungsten. Due to the high melting point of refractory metals, it is impossible to obtain products of complex shape from such metals and their alloys by traditional methods (for example, by casting or using powder metallurgy), in comparison with the capabilities of additive technologies. To obtain metal powders of tungsten or compositions based on it, which meet the requirements of additive laser technologies, the most promising technology is the plasma treatment of metal powders.

CERAMICS BASED ON ORGANOSILICON POLYMERS-PRECURSORS: PROPERTIES AND APPLICATIONS (review)

. Considers the chemical, physical and mechanical properties of polymer-derived ceramics obtained on the basis of organosilicon polymers. High resistance of ceramics to oxidation, creep, crystallization and phase separation up to temperatures above 1500 °C, high chemical resistance in harsh environments are noted. The unique set of properties of ceramics provides it with a wide range of applications, including in the composition of ceramic matrix composites (fibers and matrices), in 3D printing, in protective coatings and microcomponents for electronics. Promising areas of application of ceramics and specific examples of its current use in various constructions are considered.

METABOLIC POSSIBILITIES OF BACTERIA WITH RESPECT TO SYNTHETIC HYDROCARBONS USED IN THE PRODUCTION OF NON-METALLIC MATERIALS (review)

Current trends in various industries are aimed at the use of structural elements, their coatings and binders of non-metallic materials. The molecular structure of this group of components is basically contains organic, organoelement, straight or branched carbon-containing polymers obtained by chemical synthesis from derivatives of petroleum products. The widespread use of such materials increases the total area of their contact with the external environment, which leads to the gradual destruction of both the material itself and all structural elements as a whole. The issues of biodegradation and metabolic assimilation of polyethylene terephthalate, polyvinyls and nylon oligomers are considered.

INFLUENCE OF EXTERNAL INFLUENCES ON THE COEFFICIENT OF LINEAR THERMAL EXPANSION OF CARBON FIBER PLASTICS Part 1. Analysis of theoretical and experimental results (review)

The change in the set of deformation-strength parameters of carbon fiber reinforced plastics during aging under real operating conditions is accompanied by an irreversible change in their thermal expansion. In the first part of the work, the effect of temperature, thermal cycles, humidity, solar radiation, mechanical loads and other external factors on the coefficients of linear thermal expansion of reinforcing fillers, thermosetting polymers, unidirectional carbon fiber in the reinforcement direction, in the transverse direction and perpendicular to the reinforcement plane is considered.
