Structural and technological aspects of obtaining and processing functional composite materials based on polytetrafluoroethylene are considered. It is shown that, due to the peculiarities of the molecular structure of matrix polymers, within the framework of the traditional technological paradigm, prerequisites are created for the implementation of a structural paradox, which manifests itself in a decrease in the parameters of the stress-strain and tribological characteristics of composites with an increase in the degree of filling. Within the framework of the concept of multilevel modification, methodological approaches to the implementation of the energy and technological compliance of components, which reduce the negative impact of the structural paradox, are considered.

The structural and technological aspects of the polytetrafluoroethylene-matrix composites formation are shown. It is shown that due to the existence of inert components in the process of interfacial interaction with the degree of filling in the traditional technological paradigm implemented structural paradox manifests itself in proportion to the reduction of the parameter of tensile strength with increasing degree of filling. According to the concept of energy and technological compliance of components the technological principles to eliminate the negative impact of the structural paradox fluorine composites are proposed.

The preconditions of forming a structural paradox within the existing technological paradigm, which manifests itself in reducing the parameters of strength and tribological characteristics of composite materials based on polytetrafluoroethylene when administered in their composition of fillers and modifiers of different composition and geometry when the content of 15-20 wt. % Established effects of forming the structural conditions derating improved performance due to the formation of cluster structure of the binder particles (PTFE) and the modifier. The effective technological methods to ensure reducing the likelihood of cluster components in the manufacturing process of highly composites with a filler content of 20-35 wt. %. The technology of producing high-strength wear-resistant fluorine composites, 1.5-20 times superior to common parameters analogues produced under the trademarks "Flubon", "Fluvis", "Superfluvis.". We consider the effective use of highly fluorine composites in mechanical engineering, chemical industry and energy.
