摘要: This study aims to investigate crashworthiness and energy-absorbing capacity of CFRP multi-cell structures under the quasi-static axial loading. In the present study, CFRP single-cell and multi-cell tubes are manufactured, and the same overall dimensions and mass for all specimens are guaranteed through allocating different thickness of each side. The crushing process and energy-absorbing capacity of all specimens are experimentally investigated under the quasi-static axial crushing load. According to the experimental …
