The structural and technological aspects of obtaining composite materials based on polytetrafluoroethylene are considered. 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 multi-level modification, the technological principles are proposed to eliminate the negative impact of the structural paradox fluorine composites by controlling the structure of the organization at various levels – molecular, supramolecular, and interfacial phase. Efficient methods of manufacture of products from highly filled fluorine composites containing 25–35 wt. % carbon fiber with parameters of deformation and strength characteristics higher than the corresponding parameters of analogs.
