FIELD: transport.
SUBSTANCE: invention relates to shells of structural parts made of polymer composites to be used in space and aircraft engineering and operated at higher loads. Reinforced shell of revolution consists of skin and set of ribs. Said ribs are arranged at skin outer side. Rib section features folding and rounded angle between vertical part and folding. Prior to forming the article, filling metallic sleeve-shape elements are arranged at intersections of ribs. Extreme annular ribs are furnished with bores and filling metallic sleeve-shape elements to be fitted in bores.
EFFECT: higher durability, rigidity, stability and decreased weight.
