METHOD OF HARDENING LARGE-SIZE PRODUCTS OF COMPLEX SHAPE IN SHF ELECTROMAGNETIC FIELD OF REINFORCED WITH CARBON FIBER POLYMER COMPOSITE MATERIALS Russian patent published in 2019 - IPC H01Q13/00 B29C35/08 

FIELD: technological processes.

SUBSTANCE: invention relates to technology of electrophysical hardening of final molded polymer articles of various shape complexity. Method of strengthening in SHF electromagnetic field of large-size products of complex shape from carbon composite polymer-reinforced polymer materials includes determining, based on analysis of cross-section profile of processed article shape of total asymmetric beam pattern of antenna with required distribution of amplitudes and phases, selecting the shape of the mirror, forming a beam pattern and rotating the mirror such that the envelope of the beam pattern is equidistant to the cross-section of the article. Directional pattern is created by superimposing individual sharply directional patterns of horn antennae. Their number is selected based on the cross-sectional dimensions of the processed article, taking into account the shape of the beam pattern, intensity of excitation of each horn and dimensions, curvature of the profile and thickness of the article. An article and a mirror of the antenna are subjected to relative longitudinal discrete movement with a pitch defined by the size of the top of the total beam pattern, and mirror is provided with swinging motion in plane of article cross section by value providing compensation of error of mismatch of shape of total beam pattern and surface of article. When machining an article with variable thickness, the section with maximum thickness is located at the top of the main lobe of the total beam pattern.

EFFECT: creation at any point of the surface of a large-size article with a complex shape of the required intensity of the SHF electromagnetic field, which ensures uniform reinforcement modification of the structure of the material.
