“…The technical carbon of the N220 brand made by JSC 'Kremenchutsk Technical Carbon Plant' was chosen based on earlier investigations. 33 It is a dark-coloured substance that is 0.5-2 mm in size in its original form. Filler with such particle sizes does not allow for a considerable improvement in the degree of PC characteristics.…”

Without the employment of new equipment, with units functioning at high levels of weights, sliding speeds and temperatures, the current growth of the sector is all but impossible. High levels of labour intensity have a detrimental impact on the dependability and durability of the product. Moving joints, which comprise friction units, frequently fail at the same time. It is vital to increase their dependability and durability. This can be accomplished by substituting more recent materials with higher-quality qualities for the friction pair materials. To create such materials, the researchers created an aromatic polyamide polymer that was filled with silicon- (silica gel, bentonite) and carbon-containing (technical carbon, graphite) components. It was determined that depending on their nature, structure and content in the polymer matrix, the addition of these fillers enables the reduction of the coefficient of friction and wear of the produced polymer composites by 1.5–2.5 and 20–40 times, respectively, during frictional interaction with steel. It was found that 10–15% by weight of the examined fillers in aromatic polyamide is the ideal concentration. It has been proven that polymer composites filled with layered materials (bentonite, graphite) perform better in terms of tribological qualities when in contact with steel than those filled with spherical elements (technical carbon, silica gel). The improvement of the tribological properties of the developed polymer composites in comparison to the original polymer was determined based on the microphotographs of steel surfaces and the study of their morphological (roughness) and physical (microhardness) properties. It was determined that the change in the friction nature was due to the creation of an antifriction coating on the metal friction surface from the products of tribochemical reactions occurring during friction.

“…To this end, friction modifiers are introduced into its structure. In [7], to reduce the coefficient of friction and the amount of wear, it is proposed to add technical carbon to the matrix. It was established that the filling of the matrix with 15 wt% of technical carbon can significantly reduce the coefficient of friction and the intensity of linear wear.…”

The introduction of polymer-composite materials makes it possible not only to solve the problem of increasing durability, reducing the mass and cost of machines, but also, by introducing fillers, to adapt them to the required operating conditions. At the same time, there is a problem regarding the high cost of technologies for obtaining composites, which limits their widespread implementation. That is why the object of this research is the processes of influence of the filler on the characteristics and properties of polymer-composite materials. Complex laboratory studies of physical and mechanical characteristics, tribological and thermophysical properties of the developed polymer-composite materials based on Phenylone C2 were carried out. The dependence of the coefficient of friction and wear of the material based on Phenylone C2, containing thermally expanded graphite, on the pressure and nature of counter-bodies during friction with lubrication and without it was established. It was revealed that the minimum amount of wear of the material, with friction with lubrication, is achieved under the pressure on tribojunction of 5 MPa. It was established that with an increase in the concentration of filler from 5 to 25 wt% the coefficient of thermal conductivity increases by 4–40.8 %, compared with that non-filled with Phenylone C2. It was found that the introduction of thermally expanded graphite into Phenylone C2 in the amount of 5 wt % leads to a decrease in heat capacity by 34 %. The proposed technology of obtaining polymer-composite materials in the electromagnetic field provides sufficient physical and mechanical characteristics, tribological properties and low cost of finished products (parts). The results reported here make it possible to adapt the physical and mechanical characteristics, thermophysical and tribological properties of polymer-composite materials to certain modes of operation of movable junctions

“…To reduce the cost of prodkucts made of aromatic polyamides, the fillers that are introduced into their composition are cheaper than the original polymer matrix, which can improve the level of the physical, mechanical, and thermal properties of the designed PCMs. One of these fillers is technical carbon; work [12] reports a study into the properties of PCMs based on Phenylone and the specified filler. It has been shown that the introduction of technical carbon into the matrix makes it possible to improve the characteristics of PCMs compared to the base material.…”

This paper reports a laboratory study of the physical, mechanical, and thermal properties of designed composite materials based on Phenylone C1 filled with silica gel. Structural plastics, due to their high chemical and wear resistance, sufficient level of physical, mechanical, and thermal properties, can significantly improve the technical characteristics of machines and mechanisms. However, some structural plastics, including Phenylone C1, have a significant drawback – a narrow temperature range of their processing, which leads to a complication of technological equipment and increases the cost of production. It was established that the technical processing of the initial composite material into finished products could be improved by introducing fillers. The regularities of influence of silica gel content on the level of thermal and physical-mechanical properties of polymer composite materials based on Phenylone C1 have been established. It was found that the introduction of silica gel into Phenylone C1 leads to an increase in stress at the yield strength and modulus of elasticity at compression by 6.3 % and 13.3 %, respectively, compared to the original material. It was established that the heat resistance of the filled composite increases by 11.6 % with a decrease in thermal linear expansion by 10‒20 %, depending on the content of the filler. It was found that with an increase in silica gel concentration in the polymer matrix, the temperature of the onset of active destruction shifts towards higher temperatures. When filled in the amount of 30 % by weight, this temperature reaches 375 °C, which increases the temperature range of processing the designed material by 25 °C. The study results make it possible to optimize the system of tolerances and landings of parts made of polymer-composite materials, simplify the technology of their manufacture, and, as a result, reduce their cost
