Process and a hollow body for producing a component having at least one hollow profile

摘要

A process for producing a hollow profiled component formed by joining at least two laminated component elements, includes the steps of laminating a first of the component elements with at least one indentation, arranging a preformed hollow body in the indentation, applying an adhesive agent to a surface area of the first component element next to the indentation, placing the first component element together with the hollow body on the second component element with the indentation facing the second component element and the surface area provided with the adhesive agent contacting the second component element, covering the two component elements with a non-rigid fluid-tight covering, the interior of the hollow body being sealed off from the interior of the covering and being fluidically connected with the ambient exterior environment, placing the covered component elements in a pressure chamber, and applying a vacuum to the interior of the covering.

主权项

1. A process for producing a component having at least one hollow profile from first and second laminated component elements, said process comprising:
providing the first component element with an indentation therein; arranging a preformed hollow body in the indentation; applying an adhesive agent to a surface area of the first component element adjacent the indentation; placing the first component element together with the hollow body on the second component element such that the indentation with the preformed hollow body arranged therein faces the second component element, and the surface area provided with the adhesive agent comes in contact with the second component element; surrounding the first and second component elements with a non-rigid fluid-tight covering, with an interior of the hollow body being sealed off from the interior of the covering and being in fluid communication with ambient environment outside the covering; placing the surrounded covered component elements in a pressure chamber; and applying a vacuum to the interior of the covering; wherein arranging the preformed hollow body in the indentation includes securing the hollow body in the indentation; wherein the hollow body is provided, on its outer side, with a metal element or a magnet, and is secured in the indentation by way of a magnet or a metal element attached to an outer side of the first component element that interacts with the metal element or the magnet provided on the outer side of the hollow body; and wherein the preformed hollow body arranged in the indentation has a cross section corresponding to a cross section of the indentation and is extended into corners formed by the indentation and the second component element.
