Abstract: A component for the transmission and absorption of mechanical forces and moments includes at least one dimensionally stable component element having at least one hollow-profiled section extending along a longitudinal axis of the dimensionally stable component element, and at least one hollow-profiled component element consisting of fiber-reinforced plastic extending along a longitudinal axis of the hollow-profiled component element. The hollow-profiled component element is partially received by the hollow-profiled section of the dimensionally stable component element in a form-fitting manner. The component is produced by a method that includes the steps of inserting one end of the one hollow-profiled component element into the hollow-profiled section of the dimensionally stable component element and pressing the outer circumference (26) of the hollow-profiled component element (16) against the inner circumference (24) of the hollow-profiled section (14) by an inflatable element.

Abstract: The invention relates to a method for shaping an essentially flat-surfaced blank (10) to form a shell body (34), comprising the following steps: forming at least one flat-surfaced, buckling-stable insert (12) which is adapted to form, dimension and deformation properties of the flat-surfaced blank (10); forming a blank (14) to be deformed and at least one buckling-stable insert (16, 16?, 16?) to be deformed from the flat-surfaced blank (10, 10?) and the at least one flat-surfaced buckling-stable insert (12, 12?); placing and clamping the blank (14) to be deformed and the at least one buckling-stable insert (16, 16?, 16?) relative to one another and deforming the blank (14) together with the at least one buckling-stable insert (16, 16?, 16?) to be deformed in order to form the shell body, using at least one forming tool (32) that acts upon the front or inner side (20) of the blank (14) to be deformed or the at least one insert (16) to be deformed which is provided as a support.

Abstract: The present invention relates to a high-pressure tank made from fiber-reinforced plastic for, in particular, gaseous media, wherein, on its inner wall, the tank is equipped completely or partially with a substantially permeation-tight foil made of metal, wherein the metal has a high elastic range and a low thermal expansion coefficient, and the foil has a thickness of ?0.5 mm. The invention also relates to a method for manufacturing tanks of this type.

Abstract: The invention relates to a pressure vessel consisting of a housing and an insulating layer lining the inner surface of the housing. The housing is formed from a fiber composite material which has a high mechanical and thermal resistance and the insulating layer is formed from a gas-tight silicone elastomer, with the housing and the insulating layer being bonded to each other. The invention also relates to a method for the manufacture of such pressure vessels.

Abstract: The invention relates to a support structure for a retractable and extendable flap (12) associated with an object (14), surrounded by a flowing fluid, comprising a shell profile (16) that has a fluid/aerodynamic low-drag form on the outer side and on the inner side forms a chamber (18) for at least partially receiving a device (20) for retracting and extending the flap (12).
