Abstract

The invention relates to a method for adhering components to a composite molding. The method comprises: stacking the components provided with an appropriate bonding matter; positioning a heating device provided with at least one cavity (12), over at least a section of the stacking component; and passing a medium brought to a first temperature through the at least one cavity of the heating device, whereby the stacking component is brought at least partially to the first temperature, and each component is interconnected to the molding. The invention also relates to a device for implementing the method and a heatable membrane that can be applied in the method.

Description

technical field [0001] The invention relates to a method for bonding components to composite molded parts. The invention also relates to an apparatus for producing the composite molding. Background technique [0002] In industry, especially in the aircraft industry, methods of bonding components such as fuselage components, airfoils and reinforcements to composite moldings are often used, for example with thermosetting adhesives. For this purpose, the parts to be bonded are provided with an adhesive layer and then joined to each other. Bonding between the parts is achieved by bringing the thermosetting bonding substance to a first elevated temperature to cure the thermosetting bonding substance. In particular, it is important to remove as much air as possible between the parts and / or in the adhesive layer, as this enables the desired good bond between the parts to be achieved. Therefore, a known method consists in keeping the component within a vacuum-tight membrane, wher...
