Abstract
Aircraft radomes should provide structural integrity to protect against hazards as they house various sensors and radars that are essential for the functionality of aircraft [1]. The hazards include electromagnetic interference, lightning strikes, bird strikes, and environmental hazards. Combining polypropylene E-glass (PP/E-Glass) and Nomex honeycomb in a sandwich composite with integration of Au nanofilms can protect radomes against lightning strikes and electromagnetic interference while acting as a structural health monitoring device for damage detection. To test this, a drop-weight impact test was conducted on a fabricated PP/Glass Nomex sandwich composite with integrated Au nanofilm connected to a DC power supply and an oscilloscope. The results show that the voltage stabilized after 900 ns, confirming that the nanofilms retained their electrical integrity. Findings suggest that nanosensor can be used as a damage sensor.
