A method for producing a supporting element for a transportation device or vehicle, having steps of providing a flat base chord made of a first material having a first surface and a second surface, applying at least one layer of at least one second material to the first surface using a friction-based application or welding method, and machining the at least one layer of the second material to produce a desired profile cross section of the supporting element, wherein the first material and the second material are different metallic materials.

The invention relates to a planar structure for joining, in particular for the material-uniting joining, of at least two components. According to the invention, the planar structure is flexible and formed by at least one reaction strand. The reaction strand comprises a preferably cylindrical core, which is provided, at least in some areas, with a coating, which is constructed with a plurality of coaxially applied layers with a small thickness. To produce the layers, two different materials are used, the layers being constructed alternately with one of the two materials. Because of the high degree of flexibility of the reactive planar structure and its arbitrary area extent, components with a complex geometry in the region of the joint faces as well as large-format components can be joined in a material-uniting manner without problems. The reactive planar structure can be produced here using the methods known from textile engineering with virtually any dimensions and, in addition, by a continuous industrial production process. Moreover, the invention relates to a method for providing a material-uniting connection between two components, in particular by means of the planar structure according to the invention.

A profile plate portion is disclosed for use as an outer wall of a flow body including a first profile plate panel that is fluid permeable, a second profile plate panel extending along the first profile plate panel, and a reinforcing device for supporting the first profile plate panel and the second profile plate panel on one another. Fluid can flow through the reinforcing device, and/or fluid of the flow present at the first profile plate panel, which flows through the first profile plate panel, can flow through the reinforcing device in the local profile plate thickness direction from the first profile plate panel to the second profile plate panel and in some regions can flow through to an inside that is situated opposite the flow side. A method is disclosed for manufacturing a profile plate portion and a flow body component with a suction-extraction device for fluid.

A method for a thermal joining of two thermoplastic components includes arranging at least one reactive sheet entity in a mating zone between the two thermoplastic components. A multiply perforated metallic sheet entity configured as a bonding agent is disposed on each side of the at least one reactive sheet entity, at least in some regions of the mating zone. The at least one reactive sheet entity is activated so as thermally join the two thermoplastic components in the regions of the mating zone.

A device and method for acquiring deviations between a desired contour and an actual contour of a flexible component, in particular of a large-format metal sheet, taking into account the component's own weight. The device includes a plurality of stamps, arranged on a base area to form a stamp field, for accommodating the component at points of support, wherein each stamp comprises at least one force measuring sensor for measuring a weight force Fthat acts at the point of support, and at least one distance measuring sensor for measuring a travel path Stravelled by the stamp. For each point of support a theoretical weight force Fand/or a theoretical travel path Scan be determined from component data, wherein the force measuring sensors and the distance measuring sensors are coupled to the computing unit, and the stamps are designed so as to be controlled by the computing unit, and independently of each other can travel at least essentially perpendicularly to the base area.
