The third technique, led by Fokker Services, is the use of laser ablation, using a high power laser to remove surface coating such as paint and primer as well as damaged matrix/fibres of a composite structure. The laser ablation technology is developed and thoroughly investigated, showing that it is possible to create a very accurate cut-out with a clean surface that can be used for adhesive bonding without further surface treatment.
For this purpose, the available laser equipment at Fokker Services will be developed further to demonstrate the automated laser ablation technique on double curved surfaces as well. Since almost all aircraft parts are double curved, this is essential for applications on an aircraft or other equipment built from composite material. Besides, for full depth repair, the preparation for shallow repairs used for (stone) impact damages will also be investigated.
In order to make this technique accessible to the industry in a practical way, the research project will also include the development of tooling that can be used in an industrial (MRO) environment.
