Development of Recommendations on the of Radar-Absorbing Materials to Improve the EMC Wiring Antennas

The object of study is polymeric compositions, which will be improved by electrically conductive filler. The purpose of this work - the development of a multi-layer polymer composite radar absorbing material based on polyvinyl chloride films, filled with dispersed carbon fiber. To achieve this purpose in the work was necessary to solve the problem: develop a method of preparation of porous monolithic and polyvinyl chloride films improved by dispersed carbon fiber based on a basic prescription; analyse radiophysics radar absorbing properties of polymeric materials with different content of carbon fiber; evaluate the effectiveness of the absorption of electromagnetic radiation monolayer and multilayer films of polyvinyl chloride with carbon fiber. Based on the purpose, invented procedure for the preparation and the optimal recipe for the development of monolithic and porous PVC films filled with carbon-dispersed fiber. It has been found that multilayer films have a porous monolithic more effective absorption of electromagnetic radiation than the monolayer. Defined combination of bundle concentrations of carbon fiber in polyvinyl chloride film having optimum reflectance over the entire frequency range. It is found that the monolithic films are twice the values of physico-mechanical properties compared with the porous films. Final qualifying work contains an introduction, three chapters, 16 paragraphs, conclusion and bibliography. In the final qualifying work used 15 tables, 46 figures, 38 sources of literature. Total number of pages of the thesis - 87.
