Abstract

This article is devoted to numerical optimization of resonant narrow-band radar-absorbing materials based on polymer matrices of different density on a base of car-bonized fiber «UVZH-15C Echo» (Svetlogorsk PC«Khimvolokno», Belarus) with a di-ameter of filament 7 micron and specific resistivity 0,00003 Ohm•m. As a result of cal-culations, for a number of frequencies of centimeter and decimeter waves optimal mate-rial thickness, length and concentration of the fiber – filler were found. Features of res-onant materials optimization related to an ambiguity of definition of optimized parame-ters are taken into account. Because of that, the calculations allow you to select a type of matrix in terms of the minimum mass of 1 m2 of the material.
