The component has a first panel including a coefficient of linear thermal expansion greater than a coefficient of linear thermal expansion of a second panel. A spar (35) is made of a material having a coefficient of linear thermal expansion less than the coefficient of linear thermal expansion of the second panel. Fastening points (36) fasten the spar to the second panel by spot overmolding, screw fastening, riveting, clip fastening, strapping and dogging operations. The spar presents longitudinal direction and a profile with a slenderness ratio. The second panel is an inside panel. The first panel is an outer panel (32). The spar is made of material e.g. steel, aluminum and composite materials. |
