Innovative laser processing of coated thermal insulation foils
The project will develop technologies and a plant concept for the non-destructive, high-precision and economic processing of the complex coating systems and the underlying polymer films. The high demands on precision and the need for automation are to be fulfilled in a targeted manner by means of modern laser technology in the form of (ultra) short-pulse laser processing.
As part of the research project, suitable borehole geometries (in particular hole diameter, number and arrangement) must first be determined which do justice to the function of the pressure compensation as well as the requirements of the visual appearance (non-visibility of the boreholes). Based on this definition, the further development of the production engineering solution takes place, which makes it possible to introduce holes in the micron range into polymer films with complex thin-film systems without visibly damaging adjacent film material or coatings. At the same time, the development of the process for localized removal of the thin films from the carrier films takes place with minimal damage to the film material. Experimental investigations are used to determine suitable system technology (such as beam sources, beam guidance and shaping) as well as to develop and optimize the two laser processes with regard to the qualitative and quantitative target values. The results of the technological preparatory work are incorporated into the development of the concept for production engineering, which integrates both processes in one overall system. The final design will be finalized and tested in the form of a concept layout.
