A method and device of positioning a ply of material for a composite component along an arcuate surface are presented. The ply comprises two end portions and a plurality of fiber tows extending longitudinally between the two end portions. The arcuate surface has a curved edge and a planar surface extending from the curved edge. The method comprises placing a first longitudinal edge portion of the ply along the curved edge; and rotating at least one of the two end portions away from the arcuate surface about a pivot axis normal to the ply, so as to cause sliding of at least some of the plurality of fiber tows relative to each other, and substantial aligning of the plurality of fiber tows in a curved direction along the arcuate surface. A method of positioning a ply of material for a composite component onto a curved mandrel is also presented. 本发明提供了种沿着弧形表面安置复合组分的材料层片的方法和装置。所述层片包括两个端部和在所述两个端部之间纵向延伸的多个纤维丝束。所述弧形表面具有弯曲边缘和从所述弯曲边缘延伸的平坦表面。所述方法包括沿着所述弯曲边缘放置所述层片的第纵向边缘部分；以及使所述两个端部中的至少个绕着正交于所述层片的枢轴旋转远离所述弧形表面，以致使所述多个纤维丝束中的
