During the process of automatic fiber placement, aiming at the technological defects such as fiber folding and delamination in laying of resin-based fiber reinforced composites, this paper emphasizes on the advantages and disadvantages of different trajectory design methods (fixed angle, geodesic line, variable curvature) in technological defects. The different trajectory planning methods are compared. Finally, a trajectory design method for different surface characteristics and different wire laying process requirements is given.
