Structural component of an aircraft or spacecraft and a fuselage component arrangement of an aircraft or spacecraft

A fuselage component arrangement of an aircraft or spacecraft, comprising a fuselage portion and a one-piece structural component which comprises:

• a fuselage portion connection region for connecting to the fuselage portion, which fuselage portion connection region has a thermal expansion coefficient which is approximately matched to the fuselage portion;
• an inner connection region for connecting to an associated installation element, which inner connection region has a thermal expansion coefficient which is approximately matched to the associated installation element;
• and
• a separation region for connecting the fuselage portion connection region and the inner connection region, wherein at least one of the regions has a material structure having a high heat conduction resistance,
• wherein the fuselage portion connection region, the separation region and the inner connection region are formed in one piece with one another as the structural component, wherein the one piece structural component is as at least one of a metallic composite component or a fibre composite component,
• wherein the one-piece structural component is formed as a composite component having a common matrix material that surrounds and impregnates each of the fuselage portion connection region, the separation region, and the inner connection region along substantially the entire length of the one-piece structural component, and wherein the separation region comprises a separation composite, having a high heat conduction resistance, and the matrix material, and
• wherein a fuselage portion composite of the fuselage portion connection region and an inner composite of the inner connection region differ from the separation composite in terms of material, thermal expansion coefficient, and heat conduction resistance.
