Ceramic-Ferromagnetic-Graphite Polymer Composites for Electromagnetic Radiation Absorbing.

Electromagnetic absorbing composites modified by ceramic- ferromagnetic-graphite (CFG) fillers were first received. Ceramic-ferromagnetic-graphite polymer composites impact strength characteristics were researched and compositions with a higher silicon carbide SiC-10 % wt. content were studied, while chromium oxide Cr2O3 and graphite content in 5-15% wt. range was optimized. It is shown, that chromium oxide Cr2O3 and graphite introduction in polyamide 6-SiC 10 % wt. system increases their impact strength and breaking stress during bending. As a result of statistical data processing, the approximating curves equation were obtained, which allow to calculate ceramic-ferromagnetic-graphite polymer composites strength characteristics. It is shown that the nature of modification effect for CFG fillers on ceramic- ferromagnetic-graphite polymer composites complex spectral characteristics for absorbing electromagnetic radiation indicates the advantage in using complex system in order to receive effective materials.
