Preparation of a new nanocomposite material used in aircraft wall coatings that attenuates radar waves

Abstract

And the Boeing 787 faces modern aircraft such as Challenges to meeting the requirements of the Airbus 380 Mechanical and electromagnetic simultaneously. Electromagnetic (EM) shielding It is the ability to reflect and absorb electromagnetic radiation, acting as a shield against radiation penetration. Aside from providing electromagnetic protection from lightning strikes, conductive composites offer intentional interference with radar-absorbing materials, equipment-level shielding, protection from high-intensity radiation fields, and mitigation of human exposure. Practical research was conducted to prepare a nano-polymer composite from a nano-polymer with a 5% thermoplastic dye. The prepared nano-composite was coated with an aluminum plate, and reflectivity and frequency loss tests were performed. The coating with the prepared nanocomposite material absorbs over 96% of microwave radiation. The microwave absorption and broadband properties of the polymer composite provided the necessary barrier to radiation transmission, while continuous scattering and polarization weakened the microwaves. Tests of the prototype developed in this work were compared with those obtained for a previous patent, which showed an absorption rate of 94%.
