The expansion of the fields of application of polymer composite materials (PCM) requires the development of their new compositions, structures, and molding methods. One of the most difficult tasks in the design of PCM products is the selection or development of a polymer matrix that meets a number of technological and operational requirements. The addition of components forming an independent conditionally liquid phase to the composition of the PCM matrix makes it possible to change the set of properties of the composite and ensure its high crack resistance. The paper presents the results of evaluating the stress-strain state of model samples of carbon fiber reinforced plastic with an organosilicon polymer material that forms a hybrid matrix with the base material of the binder. Modeling was carried out for cases of using organosilicon material with low and high modulus of elasticity. Also, modeling of a front-end loader bucket made using carbon fiber with the considered hybrid matrix was performed. The simulation results showed that the use of PCM with organosilicon material in the manufacture of a product can significantly reduce its weight and provide a sufficient margin of safety.

“…The formation of such a transition layer is determined by the colloid-chemical mechanism. A weak interface at fracture makes it possible to relieve increased stresses near the crack, which makes the composite non-brittle and practically insensitive to cracks across the fibers [16][17][18].…”

“…[20] Violation of storage conditions can lead to irreversible changes in the quality of dispersed fillers, which will subsequently affect the quality of products manufactured or restored using them. But the influence of storage conditions of fillers on the change in their technological and operational properties cannot be predicted by calculation [13,14] and can only be determined experimentally [15][16][17][18][19].…”

The results of a study of the effect of storage conditions of dispersed fillers widely used in the repair of machines (mica, boron nitride, aluminum powder, carbon-containing powder) on the properties of composites based on them are presented. The results of the microstructure of the samples after exposure of the fillers under standard storage conditions, as well as high air humidity and a temperature drop, are presented.

“…The introduction of viscoelastic components into the matrix of basalt plastic is similar to the binder in living materials (for example, trees, plants, bones). Its use makes it possible to achieve high deformation properties in the zones in which they are located and prevent cracking under increased loads [5][6].…”

Basalt plastic, thanks to its complex of valuable operational properties, has a potential variety of applications. the article describes the technology of production of basalt plastics with various types of hybrid matrices, one of the components of which is cured in the molding process, and the second-like a binder in natural materials, retains its viscoelastic state. The viscoelastic component makes it possible to increase the deformation properties in the zones of their location, preventing cracking under increased loads. As a result of the conducted mechanical tensile tests, the average values of absolute breaking forces, tensile strength and elongation during fracture of basalt plastic samples with different types of hybrid matrices were obtained. The addition of viscoelastic components (such as technical wax, anaerobic, and organosilicon polymer materials) to the basalt plastic matrix allows to increase the elongation at fracture by 2...5%. Anaerobic polymer material in the basalt plastic matrix allows to increase the tensile strength of the composite material, as well as significantly reduce the dispersion of the measured values. This provides an effective prediction of the operational properties of the structural material in the design of products. On the basis of microanalysis of the structure of basalt plastics with different types of hybrid matrices, an explanation of the causes of changes in the mechanical properties of the resulting composite materials is given.
