Abstract

This paper proposes an RF-stealth sandwich composite, designed in a leading-edge shape, using Ni-coated glass fabric and an over-expanded honeycomb core, which incorporates a highly conductive nickel-coated glass fabric for lightning strike protection. The presented structure was designed and fabricated using nickel-coated glass fiber, which effectively absorbs electromagnetic (EM) waves, and an SWCNT-coated over-expanded honeycomb core, which improves sheet resistance properties. The designed RAS was subjected to an artificial lightning strike with the waveform of component A. Pristine and damaged RAS specimens from the artificial lightning strikes were measured using a free-space measurement system. The fabricated RAS specimens demonstrated satisfactory EM absorption in the X-band (8.2–12.4 GHz) and closely matched the simulation results. Damaged specimens from lightning strikes were further evaluated using micro X-ray computed tomography (CT). Given the radar absorption performance of the proposed structures, they show considerable promise for applications in stealth technology.
