Abstract: Based on 3D braiding and vacuum assisted resin transfer molding, three types of epoxy (EP) matrix three-dimensional braided composite thin-walled circular tubes with different hybrid modes (braided yarn/axial yarn: carbon fiber-carbon fiber (CF-CF), carbon fiber-glass fiber (CF-GF), glass fiber-carbon fiber (GF-CF)) were prepared. Through quasi-static axial crushing and detailed observation of failure section, the influence of fiber hybrid mode of thin-walled tube on energy absorption performance and failure mode was studied. The results show that: the specific energy absorption values of CF-CF/EP samples are 36% and 12% higher than those of GF-CF/EP and CF-GF/EP, respectively. When the braided yarns are made of carbon fiber (CF-CF/EP and CF-GF/EP), the failure mode of circular tube is folding failure mode. Carbon fiber is used in braided yarn to effectively restrain the axial expansion of central crack, and more tiny micro damage occurs in the 3D structure of folding deformation. However, when the braided yarn is made of glass fiber (GF-CF/EP), and the failure mode is flowering and bending inside and outside, the central crack is produced, and the 3D structure presents delamination and bends to the inside and outside of circular tube.
