Abstract
The results of studies into the physicomechanical properties of polymeric materials based on polytetrafluoroethylene and its composites with carbon fibres of the UVIS-AK-P brand are presented. The technology of these composites involves the plastic deformation of polymer materials by compression, accompanied by the change of thickness at a constant width of the workpiece. It was found that the use of this technology allows not only to increase the tensile strength of PTFE by a factor of 2.7–3.3 with a compression ratio of 3–4.3, but also to reduce its creep deformation by a factor of 22–29, compared to the original polymer. The proposed technology is also tested on a PTFE composite containing a carbon fiber material of the UVIS-AK-P brand in the amount of 5 mass %. It is shown that in this case, the strength of the composite increases by a factor of 3, and the creep deformation decreases by a factor of 8.3, compared to the original composite, which was not subjected to plastic deformation. The proposed technology for producing fluoroplast composites allows expanding the scope of their application, and the developed materials can be used in various friction points, especially for loading schemes with high tensile loads.
