Development of basalt – fluoroplastic composites for technical purposes

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.
