The Laser Zentrum Hannover e.V. (LZH) is working on a new laser cutting process for CFRP materials, which compensates for thermal damage occurring at the cutting edges, such as exposed carbon fibers and evaporated or melted polymatrix. Following the laser cutting, the cut kerf is coated with a powdery filler material which melts and thus seals the edge, making it a high-quality cut.
Carbon fiber reinforced polymers (CFRP) are being increasingly used as a construction material in the automotive and aerospace industry, as well as for wind energy and even in the field of sports and leisure activities.
Conventional machining processes such as mechanical and water jet cutting are no longer able to meet the demands for …
