NANO-REINFORCED RADIUS FILLER FOR AN AIRCRAFT STRUCTURE AND A METHOD OF PRODUCING AN AIRCRAFT STRUCTURE COMPRISING SUCH FILLER

摘要

The present invention relates to a composite radius filler for use in an aircraft structure (2), which comprises structural composite parts (7) assembled together to form the aircraft structure (2). The composite radius filler (3) is arranged between rounded sections (5', 5") of the structural composite parts (7) for filling a gap (4) formed between the structural composite parts (7). The composite radius filler (3) is made structural by a nanostructure (23) arranged within the composite radius filler (3) for the reinforcement of the interface between the radius filler (3) and the structural composite part (7). The invention also relates to a method for producing an aircraft structure comprising said nano-reinforced radius filler.
