Abstract
A door frame is provided at an opening made in a fuselage of an aircraft that is delimited by a skin. The frame includes an upper longitudinal stiffener and a lower longitudinal stiffener and two vertical substructures, each arranged on one side of the opening, connected by the upper and lower longitudinal stiffeners. The frame also comprises at least one stop provided at the level of the opening that uptakes radial forces exerted by the door. Each vertical substructure comprises at least three walls made of composite material that are connected to one another to form a box substructure having a closed and hollow cross-section in a sectional plane perpendicular to an axis of the length of the vertical substructure.
