The system of indicators of quality of carbon-carbon composite material and technological operations of its production is proved in the work. As a result of the experimental studies, with respect to the existing laboratory equipment, the optimal number of cycles of saturation of the reinforcing frame with a carbon matrix is determined. It was found that to obtain a carbon-carbon composite material with a low cost and the required quality indicators, it is necessary to introduce additional parameters of the pitch melt at the impregnation stage.

Abstract The paper is dedicated to studying manufacturing prospects of antenna devices from carbon composite materials and suggests technical solutions aimed at water transportation radio communication needs. Principal physical parameters of the carbon composite material used in manufacture and subsequent studies of antenna specimens were compared to those of metals. Peculiarities of manufacturing carbon composite antenna devices have been considered. Antenna specimens were experimentally studied for their electromagnetic characteristics, while their digital copies were studied in simulation. Similarities are pointed out between the main characteristics of composite antennae and their metal analogs. Efficiency of proposed technical solutions and antenna building technologies are demonstrated for application of carbon composite antennas in marine radio communication.
