Laser Zentrum Hannover, Invent, Owita, Precitec Seek New Processing for Carbon Fibers

Facebook Twitter LinkedIn Email Comments
Laser Zentrum Hannover EV has begun a joint research project with Invent GmbH, Owita GmbH and Precitec Optronik GmbH to develop a reliable process for thin-walled and complex carbon fiber reinforced polymer (CFRP) components.

The project aims to more efficiently create CFRP aircraft components. Laser-based processes allow carbon fiber tissue to be processed contact-, force- and wear-free. Moreover, the high geometric resolution of the laser makes it possible to scarf the surface precisely and to insert custom-fit replacement patches. During the patch repair, defective areas are removed layer-by-layer using the laser, and then replaced by a custom-fit patch.

An innovative system technology consisting of a laser, a scanner, a short-coherence interferometry system and a control software determines the individual process parameters according to the shape of the component. The short-coherence interferometry system measures the depth spatially with high resolution and thus ensures a precise layer-by-layer removal. Surface deformations due to local increases in thickness, which occur frequently during mechanical processing, can be avoided.

The project is sponsored by the German Federal Ministry of Economics and Energy for a duration of three years.
