Notes:
Novel PE- and PP-based electromagnetic wave shielding and absorbing materials withlow combustibility, enhanced thermal and mechanical properties, containing graphite, grinded woodand fire retardants, were developed and investigated. Their flame-resistance, thermal andmechanical properties are investigated. Electromagnetic wave reflection coefficients of the materialsover the frequency range 20-40 GHz were measured; despite low concentration (10%) of functionalfiller, reflection coefficient can be as low as -15 dB.Criteria of incombustibility of polymeric composites are formulated: thermochemical, kinetic,thermal, physical and mass transfer. These criteria allowed to set up the principles of decreasingcombustibility of polymeric composites. Materials requirements, allowing to choose the mosteffective shielding and fireproof systems for multicomponent composites, containing polymers,wood and other fillers, were formulated
