Beschreibung
Zusammenfassung:	The invention relates to wrinkle reduction in shaped composite stiffeners. The composite charge is formed into a composite laminate stiffener between two compression molds. The stiffener bar is formed along its length by forming the mold. A wrinkle diffuser attached to or embedded into or incorporated into the tool surface of the mold diffuses wrinkles formed on the inner radius of the stiffener during molding. 本发明涉及成型的复合加劲杆中的减皱。将复合装料在两个压缩模具之间形成为复合层压板加劲杆。通过将模具成型使加劲杆沿着其长度被成型。附接到或嵌入或并入模具的工具表面的皱纹扩散器使在成型期间在加劲杆的内半径上形成的皱纹扩散。
