Abstract

Abstract: Automated fiber placement (AFP) is one of the significant processes to realize manufacturing composite fuselage shear tie automatically. Path planning is the key factor of the AFP process, fiber placement path will affect the fiber angular deviation, covering and efficiency, etc. In the present study, two fiber placement paths for polymer matrix composite fuselage shear tie were designed and analyzed, also the two cured parts were inspected to explore the quality effect related on fiber placement path. The results show that for the AFP process of this part, angular deviation of the overlap & gap mixed fiber placement path is better than that of gap only fiber placement path, but its covering and efficiency are worse than that of gap only fiber placement path. For the shear tie by AFP and single-side mould, these two different fiber placement paths have a different degree of effect on appearance and thickness of the part.

Key words: automated fiber placement, path planning, quality, composite
