| Abstract:In order to design the aeroengine composite fan blade,a laminate structure design process of the composite fan blade was
established according to relative criterion. The geometric fan model detection, the volume filling laminate design, the definition of the fiber
direction, the laminate grouping and sequence regulation as well as the laminate structure inspection and manufacturability inspection were
finished for a self designed fan blade. A comparative analysis of the laminate transition along the blade height and the chord length before
and after the lamination sequence regulation was made, and the laminate manufacturability inspection and improvement were made. The
results show that the laminate structure meets the requirements of the composite laminate design criterion,the progressive laminate decrease
and transition are rational, and the manufacturability is good. |
