Stealth aircraft are aircraft that use stealth technology to interfere with radar detection as well as means other than conventional aircraft by employing a combination of features to reduce visibility in the infrared, visual, audio, and radio frequency (RF) spectrum. This philosophy also takes into account the heat, sound, and other emissions of the aircraft as these can also be used to locate it. Stealth is accomplished by using a complex design philosophy to reduce the ability of an opponent's sensors to detect, track, or attack the stealth aircraft. This paper provides a new platform towards the stealth technology with considerably less cost materials. The major contribution of the work is to introduce natural fiber composites in stealth technology. The coir fiber reinforced polymer composites are fabricated using Hand-Layup method. The fabricated composites and aluminum plates were tested for its absorption characteristics using the microwave generator setup by placing the laminate at different angles and at different distances from the transmitter terminal. The reflection loss is also calculated to compare the absorption rate for the natural fiber composites and aluminium plates.
