Abstract: This article uses carbon fiber/glass fiber inner ply unidirectional fabrics to design specimens of 4 types of various hybrid structures and 5 types of different hybrid ratios. The influence of hybrid structure and mixed ratio on the 0° tensile failure mode of C/G inner ply hybrid composites was investigated. The failure modes are given respectively in the paper. The results show that: ①The tensile failure modes of specimens with the same mixed ratio but different hybrid structures can be summed up in three categories. When we design the specimens with the same mixed ratio but different hybrid structure, the structure like should be avoided; ②The tensile failure stress and strain have the opposite trend. The tensile failure modes of specimens with the same hybrid structure but different mixed ratios can be summed up in two categories. In this case, we can get better tensile property with the mixed ratios of C/G to be around 3:2.
