LASER IN THE AIRCRAFT INDUSTRY
The aviation industry places the highest demands on surface treatment. By using innovative technologies such as laser paint removal, we at SLCR are able to work efficiently and in an environmentally friendly manner.
The development of the SLCR process originated in the aviation industry. Paint stripping of aircraft and their components is an integral part of regular preventive maintenance work. In addition, the increasingly used fiber composite components require new solutions for surface preparation as a mandatory prerequisite for further processing of the components during bonding or painting. The SLCR process for surface preparation has already become well established in the aerospace sector and already has the necessary approvals in many areas. Only by using light can the SLCR process, in contrast to conventional processes without additives such as chemicals, abrasives or other mechanical or liquid aids, perform surface preparation quickly, cleanly and precisely without post-treatment.
Thus, the SLCR process not only improves processes and reduces unit costs, but also protects the environment and significantly improves working conditions.
Specific Use Cases and Examples

Laser is the solution
Modern aircrafts need specific treatment
Laser paint stripping plays a crucial role in various areas of maintenance, repair, and overhaul (MRO). In the MRO industry, it is used to precisely remove old layers of paint from aircraft fuselages, wings, and other large components. This method ensures the integrity and structural strength of the components, which is particularly important during the regular maintenance of commercial aircraft such as the Boeing 737 and the Airbus A320.
For modern aircraft that consist largely of composite materials, such as the Boeing 787 Dreamliner and the Airbus A350, laser paint stripping enables damage-free preparation of these sensitive materials. This improves adhesion for subsequent processes such as bonding and painting, which in turn extends the service life of the coating.

Precise surface preparation is also crucial in engine maintenance, particularly for components made of nickel alloys or titanium. Laser paint removal removes the coating uniformly, which increases the efficiency of inspection and repair processes for engine types such as the CFM56 or Rolls-Royce Trent.
In addition, laser paint removal is used in the refurbishment of interior components such as seats, overhead bins, and trim panels. The laser enables the quick and gentle removal of old coatings without compromising the fire resistance of the materials.

Sustainability and Efficiency in Aviation Through Laser Paint Removal
The use of environmentally friendly and efficient technologies in aviation reduces emissions and operating costs, meets regulatory requirements, and boosts competitiveness. An outstanding example of the use of laser technology in the aviation industry is laser paint stripping. In this process, old layers of paint are removed precisely and gently using laser beams, without the use of chemical solvents. This not only significantly reduces the environmental footprint but also lowers operating costs through shorter processing times and extends the service life of components.
Improved maintenance and inspection thanks to laser processes.
Lasers are also used for the maintenance and inspection of aircraft in various critical areas. Using high-precision laser scanners, detailed 3D models of aircraft parts can be created, enabling comprehensive analysis and early detection of wear or damage. This technology is crucial for aircraft safety and reliability, as it allows engineers to identify and resolve potential problems before they become critical. These proactive measures not only ensure the safety of passengers and flight crews but also optimize aircraft availability by minimizing unplanned downtime.
Future Prospects for the Aviation Industry

APPLICATIONS OF LASERS IN THE AIRCRAFT INDUSTRY

Activation & Pre-Treatment
Fiber composites are activated by laser. Loose solvent residues and impurities are removed and by simultaneous roughening of the surface, a well paint adhesion is achieved or surfaces are prepared for bonding.

Paint Stripping & Decoating
Targeted removal of paints and coatings on parts and components, serve as preparation for subsequent processes.

Marking
Non-contact, permanent marking of fiber composites or metals, e.g. application of serial numbers or company logos. hi
