 Abstract
In this study, the collapse characteristic of CFRP/Al compound square tube was investigated experimentally. The conclusions are as follows; The impact collapse characteristic of CFRP/Al compound square tube was found to be the most superior stacking conditions . It showed that a very stable collapse mode was crushing. In the member with and , stacking conditions, fibers were splayed to the external by laminar bending, while the fibers were held between the folds of the aluminum member by laminar bending, local buckling and transverse crack. In the member with stacking conditions, fibers were held between the folds of the aluminum member by local buckling and transverse crack.
