In the aerospace area

automated fiber placement (AFP) has been widely used in the manufacture of complex-shaped composite materials. The C-beam is a typical example. The C-beam usually has a corner transition area with a large curvature. At the corner

it is difficult to ensure the placement quality and efficiency of the ±45° paths. In order to solve this problem

the influence on placement quality of the fiber number reducing method and the winding method is analyzed respectively. Furthermore

the advantages and disadvantages of the two placement strategies in the corner area are compared

and a comprehensive placement strategy is established. Finally

placement experiments are carried out on a C-beam and the results show that the comprehensive placement strategy can effectively ensure the placement quality and efficiency at the corner area of the C-beam.
