Green cockpit engineering: harnessing natural fibers for electromagnetic compatibility

Electromagnetic interference (EMI) is a critical concern in the aviation industry as it has the potential to disrupt equipment. To mitigate this situation, research on microwave absorption materials becomes crucial. The primary objective of the study is to synthesize a composite material through a hydrothermal process, combining polyaniline (emeraldine salt) composite (20 wt % polyaniline on carbon black) (PANI) with reduced graphene oxide (rGO) which is then incorporated into a natural fiber matrix. Incorporation of this material improves the microwave radiation absorption capabilities of aircraft cockpits. To characterize prepared composite materials, X-ray diffraction (XRD), Scanning electron microscopy (SEM) and Energy Dispersive X-Ray Analysis have been used. Furthermore, to assess electromagnetic properties, the Dielectric Probe kit via a microwave analyzer has been used, and this has played a crucial role in microwave absorption tests, analyzing parameters such as reflection loss. Additionally, the dielectric probe test has determined the electrical and magnetic properties of materials, elucidating their dielectric constant, loss tangent, and magnetic permeability. These comprehensive analyses have aided in developing materials that effectively mitigate the impact of electromagnetic interference on aircraft electronics.
