Abstract
The impact of organic polysulfonamide Tanlon T700 fiber on the tribological and thermophysical properties of polychlorotrifluoroethylene is considered in the article. As a result of the researches, it was found out that developed organoplastics exceed base polymer in intensity of linear wear and coefficient of thermal linear growth by 2,5-7,5 times and by 25 %. That is due to the decrease in the size of structural elements of supramolecular structure which becomes more orderly and better focused. The results of the research show that developed composition with optimal fiber content (15 mass.%) can be recommended for the manufacturing of the parts of moving joints of machines and mechanisms in various industries
Highlights
Polymer materials (PM) are highly efficient substitutes for structural materials both economically and technologically
Nowadays, the actual tasks of modern material science are purposeful increase in wear resistance and decrease of coefficient of thermal linear growth (CTLG) of PM working in tribocompounds of automotive and agricultural machinery, metallurgical and weaving industries [5]
Taking into account the above, the purpose of the work was in the researches of the impact of organic polysulfonamide Tanlon T700 fiber on the intensity of linear wear and CTLG of polymer material – polychlorotrifluoroethylene (PCTFE)
Summary
Polymer materials (PM) are highly efficient substitutes for structural materials both economically and technologically. The process of manufacturing of parts from PM is characterized with minimum energy consumption and production automation (getting several products for one cycle of formation) [1]; it completely exclude further labour-intensive and expensive machining operations (even if we are talking about complex geometric shape) [2]. Friction units of machines and mechanisms, which are equipped with polymer parts, undergo intensive wear and thermal distortion under the action of variable loads and temperatures [3]. Nowadays, the actual tasks of modern material science are purposeful increase in wear resistance and decrease of coefficient of thermal linear growth (CTLG) of PM working in tribocompounds of automotive and agricultural machinery, metallurgical and weaving industries [5]
