To investigate the effect of interlaminar properties on the tensile properties of fiber hybrid composites, two kinds of epoxy resins with different toughness, 7901 and 9A16, were used as the matrix. Interlayer carbon/glass hybrid composites with different numbers of carbon fiber layers were designed and manufactured. The effects of mode Ⅱ interlaminar fracture toughness (G_ⅡC) on the failure mode and mechanical properties of carbon/glass hybrid composites were investigated through both theoretical and experimental investigation. The results show that, the higher mode Ⅱ interlaminar fracture toughness is, the more the carbon layer tends to fail in fragmentation, achieving a higher critical thickness for fragmentation, which is beneficial for achieving pseudo-ductility. In addition, the GⅡC on the modulus and strength of hybrid composites is marginal, as the variation is within 5%. However, the GⅡC demonstrates a significant impact on the pseudo-ductility strain, which is decreased by 40.7% when the GⅡC is increased from 1.75 N/mm to 2.08 N/mm.
