Abstract

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
