Abstract
In this paper, a manufacturing method for composite materials that absorb electromagnetic waves in the form of blends of EMCCO-201 with SBS (styrene-butadiene-styrene copolymer, trade name Kraton) is shown and the absorption characteristics of the prepared samples are discussed. The materials were manufactured on the basis of extrusion technology. The absorption characteristics of the tested materials were measured as a function of the testing signal angles of incidence. The samples were 300 × 300 mm, made of aluminum alloy sheet and covered with either absorption elements that were spheroids of diameters 1–2 mm and 3–4 mm made of 50 vol. % of EMCCO-201 with SBS (styrenebutadienestyrene) copolymer or pyramids with a 25 × 25 mm base and height of 50 mm made of epoxy resin covered by spraying with a layer of EMCCO-201 material without SBS copolymer. Absorption measurements were carried out in the frequency range from 3.0 to 11.0 GHz. The largest absorption of 5.5–6.0 dB at the frequency range of 7.0–10.0 GHz was obtained for samples with the epoxy resin pyramids of a square base 25 × 25 mm and height of 50 mm covered with a layer of EMCCO-201 material. The samples with the spheroids showed smaller absorption between 1–3 dB at the same frequency range.
