Aircraft, especially a rotary-wing aircraft, especially a helicopter, comprises a structural component at risk from impact or explosion which is made of a plate- or shell-like lightweight composite material with at least one first rigid, strong support layer (2) produced from at least one metal material or a composite material, and at least one elastomer layer (4) fixed to the support layer. The elastomer layer is completely penetrated by reinforcing fibers (6) and forms a matrix for the reinforcing fibers. Preferred Features: The support layer comprises an aluminum material. The structural component is a base assembly or a base assembly component of the aircraft, a component of the power plant, a fuel tank arranged in a base element, or a fire-protection element.
