MULTI-LAYERED COMPOSITE MATERIAL FOR PROTECTION AGAINST ELECTROMAGNETIC RADIATION |
摘要 |
FIELD: chemistry.SUBSTANCE: invention relates to means for protection against electromagnetic fields of electrotechnical and electronic devices and biological objects and can be applied for creation of electromagnetic screens and echo-free chambers. Composite material for protection against electromagnetic radiation consists of polymer base with distributed in it particles of alloy of system Fe-Cu-Nb-Si-B, and is characterised by the fact that it represents multi-layered construction, each layer of which is made of said composition, and content of alloy particles in each layer constitutes 70-90 wt % and is limited by certain range of size of particles from continuous line 1-200 mcm with increase of particle dimensions in each following layer.EFFECT: increase of working range of material frequencies from 100 MHz to 10 GHz with preservation of low values of reflection coefficient and high values of magnetic permeability.3 cl, 1 tbl, 2 dwg, 2 ex |
