Abstract

A process of plastic deformation of polymer blanks based on polytetrafluoroethylene (PTFE) and a polymer composite material (PCM) based on UVIS-AK-P carbon fibers was developed to improve the strength and creep resistance of the materials. The physicomechanical and tribological properties of the composites obtained were studied and compared with those of a composite that had the same composition but was obtained using a previously developed process. It was determined that the process of plastic deformation of PTFE-based PCM and UVIS-AK-P carbon fibers is an efficient approach to obtaining high-strength wear-resistant composites with enhanced resistance to tensile load. The tensile strength tripled and the creep decreased by a factor of 22 to 29 in comparison with those of the PTFE and PCM samples not subjected to plastic deformation. Structural studies showed that this process leads to the orientation of carbon fibers (CFs) in the direction of the material flow and to the transition of the helical conformation of macromolecules to a more stable conformation, which has a favorable effect on the performance of the materials developed.
