Abstract The development of composites based on polytetrafluoroethylene (PTFE) for their use in friction units of technology in the Arctic climate is an urgent task of modern materials science. The active use of environmentally friendly fibers as reinforcement for composite materials instead of carbon and fiberglass can help reduce environmental problems. Moreover, from an economic point of view, natural fibers are in an advantageous position. In this work, the effect of basalt fiber on the tribotechnical properties and structure of polytetrafluoroethylene is investigated. As a result of the study, it was found that the characteristics of basalt fluorocarbon composites are approximately on par with composites with carbon fibers. Thus, basalt fiber can become a new cost-effective, and most importantly, an environmentally friendly replacement for traditional fibers. © 2022 The Authors. Published by ELSEVIER B.V.

Keywords: fluoroplastic, polytetrafluoroethylene, polymer composite, basalt, fiber 1. INTRODUCTION Fibrous heat-resistant materials based on igneous rocks are of the most significant interest in developing efficient and affordable materials. The main advantages of polymer composite materials made with such fibers are their availability, low cost of raw materials, and high thermal and chemical resistance (Chaimelov and Strogonov (2021)). 15th International Conference on Mechanics, Resource and Diagnostics of Materials and Stru tures Development of basalt – fluoroplastic composites for technical purposes A.A.
