High structural insulation composite material development with electromagnetic protection effect reinforced with carbon fibers and particles

Abstract

Many articles in the literature discuss about the harmful effects of electromagnetic waves emitted by electrical and electronic devices on human health. The composite panels, which are the subject of this study, are designed with the inspiration of the absence of a protective wall covering material from the effects of electromagnetic waves in the market. This study aims to develop a material with electromagnetic insulation as well as heat and sound insulation for especially civil engineering and space engineering applications. In the study, panels are produced by adding carbon fibre and carbon particles into the polyurethane matrix. Heat transmission coefficient tests, sound absorption measurement tests and electromagnetic protection efficiency tests have been made for panels. As a result of the tests, electromagnetic protection values ranging from 22 to 83 dB were obtained from panels and heat transfer coefficient values were found to be less than the standard values of 0.06 W/mK and sound insulation values were found to be having the lowest 0.22 and the highest 0.90 Hz sound absorption coefficient. In addition to the above findings, the composite panels were elastic, lightweight and smooth. Finally, it is determined that the composite panels developed in this study satisfy the conditions required for heat, sound and electromagnetic insulation for engineering applications.
