The use of carbon composites has continuously increased in the commercial aircraft industry due to more challenging weight targets which is one way to handle the environmental requirements to lower the CO2 emissions. One aircraft structure component made at Saab Aerostructures is long and slender U-sections manufactured in carbon composites. The manufacturing is performed by manual layup of composite material. These U-sections are selected as an illustrative case in order to discuss possibilities for an automated manufacturing process with the aim to reduce cost. A literature review of different existing technologies have been performed and compared with the industrial front at Saab Aerostructures. Automated Tape Laying (ATL) and Automated Fibre Placement (AFP) are the two dominating automation methods, of today, for aircraft prepreg manufacturing. Both methods are heavy investments for small to medium size composite manufacturers. Analysis in the case has shown that the selected component cannot be automated with these two methods due to design constrains. The paper suggests that another automated method with a cutting machine in combination with an industrial robot with a vacuum gripper, is selected for further work. The proposed pick and place process is also assumed to reduce the material waste.
