Extended Abstract: A wide utilization of electronic equipment produces the need in integration of building and shielding technologies. This would allow to construct premises and buildings, capable of attenuation of the electromagnetic fields, generated by industrious and household sources. Such kinds of premises would solve the problems of electromagnetic compatibility, uncontrolled effect of electromagnetic radiation (EMR) on humans’ organisms, protection of critical types of information assets, processed by automatic facilities. In addition to the high shielding effectiveness the materials should ensure the fire safety in the premises. The developed multilayered shielding materials based on composites, which are characterized by high dielectric and magnetic losses, ensure the EMR attenuation 20…35 dB in the frequency range of 0,7…17 GHz. The EMR reflection factor, ensured by the suggested materials, is -5…-1 dB. Open fire (+1700ºС) impact on the developed materials was studied and the burning-through time for different samples was determined. The burning-through time is sufficiently increased upto 140 s due to hygroscopic aqueous solutions application in the composite materials content.
Key words: fire safety, composite materials, shielding effectiveness.
