METHOD OF FORMING SANDWICH STRUCTURES AND STIFFENED PANEL STRUCTURES |
摘要 |
A novel method of forming complex structures by using an accordion expansion process is disclosed. The process involves a plurality of flat workpieces of predesigned shapes and sizes that are positioned in such a manner, that after the workpieces have been first joined together, they are expanded to form high strength structural members of complex design. |
