Dependence of coefficient of reflection of EMI of the multilayered composite material received by addition of sheets filled with dispersed carbon fiber of polyfoam and a nonwoven cloth, on structure of separate layers is investigated. At a certain structure of layers receiving a multilayered material with high efficiency of absorption of low-frequency range of EMI is reached. Combining of layers of radar absorbing foam and nonwoven cloth provides a modification of electrical properties of multi-layer composite material.
