Abstract

The development of modern technologies requires the use of new innovative materials. PA series polyamides, which belong to thermoplastic polymers, are widely used in structural elements of automobiles due to their strength, wear resistance, resistance to chemicals and heat resistance. The heat resistance of polyamide is extremely in demand in the engine compartment, where long-term operation at high temperatures is required from plastic. Glass-filled polyamides, which are close in properties to ceramics, are used in the production of sockets and switches. Isotropic shrinkage polyamides are used for precision casting in electronics. In this regard, there is a need to determine the dynamic mechanical characteristics of polyamides.

The following grades of polyamides were taken as objects of research: PA 610 (fuel and oil pipes (automotive industry), cable sheaths, sports equipment), PA 610-RM (parts requiring increased strength or heat resistance, insulation in electrical engineering, friction units with a low coefficient of friction), PA 6-LT-U1-RM (structural parts, gears, bearings, electrical housings, automotive components), PA66 - 2 (friction units, gears, terminal blocks, sockets), PA66-2RM (units with high mechanical load, parts with constant operation at elevated temperatures, insulating materials, guide bushings). PA6-LT-SVU2 (TU 6-05-211-1411-85), PA66-1-L-SV30(TU 6-05-211-1424-86).

This article describes the results of dynamic compression tests of polyamides.

Key words: polyamide, electrical materials, automotive transport, modern mechanical engineering, insulating materials, impulse loading, dynamic tests, tribotechnics.
