| 中文摘要: |
| 为了设计航空发动机复合材料风扇叶片，根据相关准则，系统建立了复合材料风扇叶片的铺层结构设计流程，针对某自
行设计的风扇叶片，完成了叶片的几何模型检测、体积填充铺层设计、铺层纤维方向的确定、铺层的分组与顺序调整，以及铺层的结
构检查与可制造性检查。对铺层顺序调整前后沿叶高及弦长方向的铺层过渡进行了对比分析，完成了铺层的可制造性检查与改进。
结果表明：铺层结构满足现有复合材料铺层设计准则要求，铺层的递减过渡合理，可制造性良好。 |
| 英文摘要: |
| 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. |
