摘要
In a curved portion of a fibrous preform having a radius of curvature that is smaller than the thickness of the superposed layers (12), an insert (14) is introduced between two of the layers. The insert comprises a first curved surface (14a) having a first radius of curvature substantially equal to that of a surface of the layer adjacent an outer side of the preform, and a second curved surface (14b) having a second radius of curvature greater than the first radius of curvature and substantially equal to that of a layer adjacent an inner side of the preform.
