Abstract: A radar-absorbing fiber-reinforced structure includes a fiber composite discharging part. The fiber composite discharging part includes a first electrode part and a second electrode part, which are spaced apart from each other by a dielectric layer and receive different voltages. The fiber composite discharging part is configured to discharge plasma in response to a voltage difference thereby changing a reflected wave or transmitted wave of a radar incident on the radar-absorbing fiber-reinforced structure to reduce reflectivity of the radar. At least one of the first electrode part and the second electrode part include a conductive fiber having a tensile strength equal to or more than 0.5 GPa.
