“…Эксперты считают, что до 2027 года рынок композитов будет расширяться на 6,8% в год и по стоимости возрастет до 112 млрд долл. [4]. Высокие темпы развития рынка композиционных материалов, в том числе строительных и теплоизоляционных, определяются широким спектром их свойств, превосходящих свойства традиционных материалов, а также вариативным подходом к созданию изделия, начиная с моделирования его структуры, свойств и формы и заканчивая выбором технологий производства [5].…”

THE PURPOSE. One of the directions of energy saving and energy efficiency improvement is the reduction of consumption of fuel and energy resources. A large amount of thermal energy is spent on heating buildings and structures during the heating season. To reduce heat losses through the building envelope, various heat-insulating materials with low thermal conductivity are used. The purpose of this research was to study the problem of developing the technology of lightweight concrete based on diatomite rocks, as well as uneven inclusions of filler from microspherical granules arising during its creation, assessing the effect of the presence of zones not occupied by microgranules on the insulating properties of the composite material, as well as determining the effect of the volume content of microspherical granules on the value of thermal conductivity.METHODS. In this work, we studied the production of lightweight structural concrete with porous aggregate synthesized from diatomite rocks of the Vladimir region, as well as the effect of the presence of zones not occupied by microgranules on the insulating properties of the composite material. RESULTS. The results showed that the distribution of microgranules in the matrix has a significant effect on the insulating properties of the composite, and the presence of voids in the material contributes to heat losses and a decrease in the thermal resistance of the material.CONCLUSION. The technology for obtaining the developed concrete does not differ from the technology for the production of high-class concrete, which allows the use of widely used concrete equipment.

“…There is a growing interest in the use of materials based on carbon fiber. According to analytical studies, it is expected that the consumption of carbon fiber in the world will actively grow and reach $ 8 billion in 2026 [4,5]. The increase in consumption of PCM in various areas of production and economy is determined by their high specific strength and corrosion resistance compared to known metals and alloys, as well as compared to single-component polymers [6,7].…”

Tests of control and microwave-modified samples of carbon- and glass-reinforced plastic were carried out according to the scheme of threepoint bending. The sample's temperature was -200C. It has been established that microwave exposure on to these materials for two minutes in the cured state at an energy flux density of (17-18) x104 and (22-25) x104 μW/cm2, respectively, contributes to an increase in bending strength by 12% and 15% with an increase in the uniformity of the parameter in a batch of samples from 1.5 to 4.9 times. It has been established that the accumulation of destructive damage in the prototypes occurs over a 2.5-3.5 times longer period of time than the control ones. The difference in the mechanisms of destruction of control and experimental samples is noted. If the destruction of the control samples has a brittle nature, then for the prototypes there is a tendency to the appearance of a plastic component.

“…The analysis of scientific and technical information indicates the intensive development of the production of polymer composite materials (PCM) reinforced with fabrics based on carbon, glass, aramid fibers and their application in the aerospace and defense industries, wind energy, as well as automotive and shipbuilding, and construction. By 2026 the growth of market of high-quality carbon fiber from 3.9 billion dollars in 2019 up to 8.0 billion dollars is predicted, and the annual increase in the production of fiberglass is currently 8−10% annually, and this trend will increase [1].…”

It has been established that exposure to a microwave electromagnetic field with an energy flux density that is rational for each type of composite (carbon-, glass-, organoplastic) contributes to an increase in the specific work of delamination by 18.6%, 12% and 20%, respectively, which satisfactorily correlates with an increase in strength of these materials under three-point bending and interlaminar shear. Keywords: carbon fiber reinforced plastics, fiberglass plastics, organoplastics, delamination, microwave electromagnetic field.
