摘要: 介绍了复合材料框的结构特征和制造技术发展趋势,针对大尺寸复合材料Z形加强筋大曲率弧形,同时存在阴、阳模拐角的结构特点,提出了一种无软盖板的成型方案,在成型工装设计时选用Invar钢,对内缘条回弹角进行补偿设计,产品制造过程重点控制拐角区域厚度、表面质量、固化变形以及拐角区域铺贴质量,研制的Z形加强筋可以很好地满足各项技术指标要求。该复合材料Z形加强筋成型方案质量高,适合工程化推广应用。

Abstract: In this paper, the structure characteristics and manufacturing technology development trend of composite frame are introduced, according to the structure feature of large curvature radius and both male and female corner of large scale composites Z-shape stiffener, this paper introduces a manufacturing method without soft cover plate during forming process, the Invar steel material was chosen to manufacture the forming tooling, and the springback angle of Z-shaped stiffener inner flange was compensated during the design process of tooling. The key point during product manufacturing is to control the thickness of corner area, surface quality, curing deformation and the hand lay-up quality of corner area. The developed Z-shaped stiffener by this method can well meet the requirements of various technical indexes, this is a high-quality manufacturing method for large scale composites Z-shape stiffener, and this method is suitable for engineering promotion and application.

Key words: composites, Z-shaped stiffener, manufacturing technology
