Abstract
Isogrid structures have a higher specific strength and stiffness, they are composed of triangular grid stiffeners and a face layer. One of features in isogrid structures is the offset part which is effective for avoiding stress concentration at the cross points of grid stiffeners. These structures are being mainly used for aerospace applications. In order to produce a metal isogrid cylindrical shell, a majority of thick metal plate is milled to produce the isogrid panel and then its both ends are welded to each other. Therefore, unstable behaviors of isogrid structures are generally observed in the joint parts. However, the CFRP isogrid cylindrical shell can be simultaneously fabricated the parts of shell and grid with a filament winding method. In this study, a molding of isogrid CFRP cylindrical shells is proposed and their compression tests are also conducted to investigate the stiffening effects of isogrid CFRP cylindrical shell. Furthermore, the results of the compression tests are compared with numerical ones obtained by FEM.
