AI Technical Summary

Technical Problem

Existing technologies make it difficult to achieve integrated forming of complex curved structures when manufacturing curved thin-walled structures. Furthermore, the internal support system is arranged in a specific direction, resulting in insufficient lateral load-bearing capacity and poor local stability. There is also a lack of systematic structural reinforcement design.

Method used

An additive manufacturing technology is used to integrally form a radially reinforced multi-cavity curved thin-walled component, including an outer shell, an inner shell, and a radial stiffener structure. A stable lateral force transmission path is formed by continuous fiber reinforcement material, which enhances the interface connection strength.

Benefits of technology

It significantly improves the lateral load-bearing capacity and bending stiffness of curved thin-walled components, alleviates local stress concentration and instability problems, enhances overall reliability and fatigue life, and reduces manufacturing costs and cycle time.

Abstract

The present application relates to a kind of additive manufacturing radial reinforcement multi-cavity curved surface thin-walled component and its preparation method, belong to composite material structure design and manufacturing field.The component is integrally formed by additive manufacturing, including outer shell, inner shell, internal cavity and radial reinforcement structure.Shell is divided into outer shell and inner shell, internal cavity is arranged between the two, and the overall structure is curved shape.Radial reinforcement is arranged between adjacent internal cavity, and it is connected with outer shell and inner shell along the height direction, for improving the transverse support capacity and overall bending stiffness of structure.The radial reinforcement of the present application is integrally formed, so that the curved surface thin-walled component obtains effective cross-layer support.Radial reinforcement and internal cavity side wall form a stable stress system, significantly improve the bending stiffness, ultimate bearing capacity and load-mass ratio of structure, optimize the interface stress distribution, inhibit peeling and delamination failure, and fully exert the advantages of additive manufacturing in the integrated forming of complex configuration.
