The Effect of Plastic Deformation Technology on Mechanical Properties of Polytetrafluoroethylene-Based Composites

A process of plastic deforming polymer blanks is developed involving polytetrafluoroethylene (PTFE) and carbon fibers of the UVIS-AK-P grade. The production process is explored from the standpoint of increasing the strength and resistance to creep. The relationship is found between the physics, mechanical, and tribotechnical parameters and the structural composite properties. The composites obtained using various schemes of plastic deforming polymer blanks differ in the character of deformation under tension. They develop different structures and feature various wear patterns. A multidirectional approach to plastic deforming blanks based on PTFE allows obtaining isotropic polymer materials featuring improved strength properties and better resistance to deformation under load.
