Features of Technology for Obtaining Polymer Composite Materials Based on Polytetrafluoroethylene (Review)

Abstract

The experience of many theoretical and practical works concerning the technology of PTFE-composites formation has been analyzed and systematized. The peculiarity of the work consists in the fact that PTFEcomposites reinforced by carbon fibers are considered to be complex objects with properties characteristic to tribotechnical material science of composite materials. The structure complexity of such objects provides their consumer properties due to many factors, which influence the significant increase of physicomechanical characteristics. The research results defined operation regimes of process equipment: after the processing PTFEcomposites have increased operation properties in comparison with basic and can be most effectively used for industrial implementation.Keywords: polytetrafluoroethylene, polymer composite, technology, mechanical activation, mixing, pressing, sintering, structure, properties.
