Radar absorbing structure

A radar absorbing structure (1) comprising:

• a body (2) that forms the air and/or space vehicle;
• at least one aerodynamic surface (3) located on the body (2);
• at least one resistive layer (4) which is located on the at least one aerodynamic surface (3) and allows substantial damping of electromagnetic waves on the at least one aerodynamic surface (3) by means of the destructive interference;
• a plurality of fibers (5) located in the at least one resistive layer (4);
• at least one binding agent (6) that holds the plurality of fibers (5) together;
• at least one film (7) which is located between the at least one aerodynamic surface (3) and the at least one resistive layer (4) and/or on the at least one aerodynamic surface (3) to remain above the at least one resistive layer (4), wherein the at least one film (7) is cured together with the at least one aerodynamic surface (3) and the at least one resistive layer (4) to form a cured composite layer formed by the aerodynamic surface, the film, and the resistive layer, which together provide impedance matching and destructive interference;
• a first film (701) located on the at least one resistive layer (4) and containing the plurality of fibers (5);
• and
• a first binding agent (601) allowing the plurality of fibers (5) to be held together, which is obtained by mixing the binding agent (6) with graphene (G) in powder form and electro-active polymer (P), wherein the first binding agent (601) is applied on the first film (701) to form, together with the plurality of fibers (5), a resistive composite layer that contributes to the impedance-matching and destructive-interference performance of the radar absorbing structure (1).
