Abstract: In this paper, 0°/90° glass fiber non-crimp fabrics and 0°/90° carbon fiber non-crimp fabrics composite laminates with different hybrid ratios were formed by Vacuum Assisted Resin Infusion (VARI) process, and the effects of different hybrid ratios and hybrid ways on hybrid composite tensile and low velocity impact performance have been studied. The results are as follows: the tensile and low velocity impact properties of glass fiber composites are greatly improved when small amount of carbon fibers are added; glass fiber covered surface and inter-layer hybrid structure have the best tensile properties in the same kind of hybrid ratios; for the low-velocity impact properties of hybrid fiber composites, the impact energy, the expansion energy, the toughness index are decreased and the compressive residual strength properties of damaged composites are improved with the increase of carbon fiber content. Meanwhile, glass fiber covered surface and sandwich hybrid structure show the best performance of the low-velocity impact when the contents of carbon fibers and glass fibers are close. Otherwise, glass fiber covered surface and inter-layer hybrid structure have the better impact performance.
