If we want to maintain, or even increase, the current level of use of high-performance composite materials, some major challenges need to be solved: reduction in the cost of the final structure, reduction in energy consumption during the manufacturing cycle from the base material to the final structure, and develop strategies following the “5Rs Circular Economy” approach: Rethink, Refuse, Reduce, Reuse and Recycle technologies to produce materials and structures with high added value. This communication has the intention to show Airbus work on the reuse of multilayer uncured prepreg scrap generated in AFP, to be used for the manufacturing of non-loaded parts by BMC (Bulk Moulding Compound). We will deal with the problem understanding; multilayer prepreg scrap represents an important part of the fresh scrap generated in the manufacturing plants and no feasible technology has been yet developed to treat this type of residue due to the difficulty of separating layers without completely damaging the composite prepreg. We will also detail the multilayer prepreg scrap treatment, part production, material characterization, and the opportunities to introduce parts made of reuse prepreg on real aircraft.
