In this work, the properties of a composite material derived from fluoroplast and bentonite are examined. The results of the investigation of tribal properties obtained on the basis of fluoroplast and bentonite filler with concentrations of 0.1% are presented; 0.2%; 0.5%; 1%; 2%; 5%. Wear resistance at 5 wt. % bentonite in PTFE increases 117 times compared to the original PTFE after 1 hour and 65 times after a three-hour test.

This paper presents the results of studying of the physics and mechanical and partially tribotechnical properties of fluoroplast-based and bentonite filler. Research has shown that elasticity increases at bentonite concentrations of 0.2% and 0.5%, then decreases sharply. The wear resistance (1h. test) at 5 wt.% of bentonite in PTFE increases 116 times relative to the initial PTFE.

The elasticity problem is widely used in various fields of engineering and construction, as well as in materials science and mechanics. This work examines the application of elasticity problems for analyzing the behavior of materials under various loads and influences, as well as for calculating deformations and stresses in structures and elements[3]. Numerical modeling of elasticity problems is a relevant and important area in engineering practice. This method makes it possible to predict the behavior of materials under different loads and conditions, which is essential for the design and analysis of various structures. Perforated domains play a key role in engineering applications; however, the presence of holes can significantly affect the mechanical behavior of the material[1]. This article focuses on presenting mathematical models and numerical methods for analyzing the behavior of materials with perforations. Such models make it possible to account for the influence of hole geometry, their sizes, and arrangement on the distribution of stresses and deformations. Numerical modeling is carried out using the finite element method, the FEniCS library, the gmsh program, and visualization in Paraview.
