【 摘 要 】

Summary. The rapid development of industry and increase its competitiveness requires the development of new materials, including polymer composites based on polyamides. In order to improve the performance and expand the applications of the polyamide binder is introduced particulate and fibrous fillers. Organic fibers, as compared with other polymers are of good wetting, high bonding strength with the matrix less prone to breakage, high specific strength and stiffness. The aim of the work is the creation and study of the properties of composites based on polyamide - PA-6 aliphatic and aromatic - phenylon C-1, filled polyimide fibers arimid-T. The technology of preparation of polymer compositions comprised of the following steps: mixing, pelletizing, drying and molding. Mixing of the compositions was performed in a rotating electromagnetic field. Under the action of the rotating electromagnetic field, ferromagnetic particles cаme into intensive chaotic motion, which leads to a uniform distribution of fibers in a polymer matrix. Molding samples was performed by compression molding. We study the thermal, physical, mechanical and tribological properties of polymer composites created. It was established that the reinforcement polyamides leads to increased strength characteristics composites. For organic plastics (OР) based on the C-1 phenylon reinforced 15% of the mass Arimida-T, yield strength in compression, Rockwell hardness, modulus of elasticity, microhardness higher than the starting polymer at 13; 61, 20 and 68%, respectively. For ОР based on PA-6, the compressive yield stress and break microhardness modulus of elasticity with increasing degree of reinforcement binder increases by 47, 54, 25 and 36%, respectively. The highest wear resistance and low friction have composites based on PA-6 (30 % of the mass аrimida-T) and through phenylon C-1 (15 % of the mass оf the fiber). Thermophysical composites research confirmed the presence of interactions at the interface fiber-binder.
