Description

technical field [0001] The invention belongs to the field of aviation composite material preparation and molding, and relates to an L-shaped composite material member laying mold and an operation method thereof. Background technique [0002] Composite materials have the advantages of light weight, high specific strength and specific stiffness, fatigue resistance, corrosion resistance, and high temperature resistance. They are widely used in the aviation industry and gradually extended to aircraft load-bearing components. However, due to the anisotropy and laminated structure of composite materials, it is difficult to achieve accurate molding of composite components, especially components with complex profiles. During the preparation and molding of composite components, the design thickness cannot be accurately guaranteed, and even pores, etc. Therefore, it is necessary to design an L-shaped composite component laying mold to realize the precise forming of the L-shaped compos...

AI Technical Summary

Problems solved by technology

However, due to the anisotropy and laminated structure of composite materials, it is difficult to achieve accurate molding of composite components, especially components with complex profiles. During the preparation and molding of composite components, the design thickness cannot be accurately guaranteed, and even pores, etc. Therefore, it is necessary to design an L-shaped composite component laying mold to realize the precise forming of the L-shaped composite component and ensure the design thickness and internal compactness of the molded part.

[0003] At present, the preparation and molding process of composite components with complex profiles has attracted widespread attention. In the research and production process, manual pressing is often used for molding. Not only is the operation efficiency low, but it is also difficult to achieve accurate molding of the profile, which affects the performance and use of components. reliability

There are mainly the following deficiencies: 1. The complete and continuous molding of the profile cannot be realized; 2. The precise control of the thickness of the component molding cannot be guaranteed.

The molding thickness of the component and whether the interface surface is smooth and continuous will have an impact on the volume content of the components of the composite material, and then affect the mechanical properties of the component.
