FIELD: transport.
SUBSTANCE: inner facing elements and mechanical elements are attached to outer body by means of self-bearing structural element made from composite material equipped with multiple inner elements to allow connection thereto of other inner facing elements, body elements and mechanical elements in whatever sequence of assembly. Then, foam density is selected subject to structural peculiarities or to mechanical-and-vibration peculiarities of mechanical elements jointed thereto, to force said foam into self-bearing element cavity to make it stiff.
EFFECT: reduced production costs.
