A method for producing a crossmember for a vehicle prepares a workpiece having different thicknesses and a preliminary contour from a metal sheet of uniform thickness by flat roll forming to achieve different local thicknesses. The method cuts out the workpiece, and bending roll forms the workpiece to form a crossmember with a cross section having at least two flanges opposite one another, and a web situated between said flanges. The distance between the flanges is not constant along a longitudinal extent of the crossmember, and a thickness profile at least of the web is determined by the flat roll forming. The local thicknesses and the preliminary contour are such that a geometrical shape of the crossmember corresponds to a predetermined geometrical shape with different thicknesses and heights of the web and differently shaped regions of the flanges along the longitudinal extent of the crossmember.

An aircraft frame includes a first partial aircraft frame configured to be attached to a first aircraft fuselage segment, and a second partial aircraft frame configured to be attached to a second aircraft fuselage segment. The first and second partial aircraft frames include corresponding first and second stringer coupling sections. The first partial aircraft frame and the second partial aircraft frame are configured to be attached to each other via a first web and a second web. The first stringer coupling section is located between the first inner flange and the first outer flange and the second stringer coupling section is located between the second inner flange and the second outer flange. The first stringer coupling section includes a first wall which extends from the first web into the first section of the first partial aircraft frame, and the second stringer coupling section comprises a second wall, which extends from the second web into the second section of the second partial aircraft frame.

A method for connecting two components is proposed where a pressure acting on an adhesive between two join partners is supported by an auxiliary body which rests on a cutout of one of the components. Both components to be connected together and the auxiliary body are covered by a vacuum film and once the air has been sucked out, the compressive force is generated below the vacuum film.
