Method, system and molding tool for manufacturing components from composite fiber materials

摘要

In a method for manufacturing components from composite fiber materials, at least one placeholder is inserted into a recess in a molding tool, wherein the unfinished component is subsequently produced, the placeholder is removed, at least one lifting pad is inserted into the recess and the unfinished component is removed from the molding tool by inflating the lifting pad. In a system for manufacturing components from composite fiber materials, the component removal process is monitored and controlled by a computer unit in order to prevent predetermined maximum component loads from being exceeded. The gentle component removal process makes it possible to avoid consequential costs for repairing or reworking the components.

1. A molding tool system for producing a component from composite fiber materials, the system comprising:
a molding tool having at least one recess; a placeholder for each of the at least one recess; at least one lifting pad; wherein the at least one recess lies in a trimming region, the trimming region lying outside a desired shape of the component to be manufactured and into which trimming region the component to be manufactured extends, wherein the molding tool comprises a first area and a second area peripheral to the first area, wherein the first area is configured such that the unfinished component lies flush there, and the second area is configured to receive the trimming region of the component, and wherein the at least one recess is arranged in the second area; wherein the placeholder is dimensioned for being inserted into the at least one recess in the molding tool such that the at least one recess is filled out and such that the placeholder ends flush with the surface of the molding tool, wherein the at least one recess is dimensioned for receiving the respective placeholder such that when an unfinished component is produced in the molding tool, the respective placeholder is removable from the at least one recess and for subsequently inserting the at least one lifting pad into the at least one recess from outside the molding tool, and wherein the at least one lifting pad is adapted for being inflated after being inserted into the at least one recess.
