This study dealt with the tensile strength and fracture mechanism of quasi-isotropic carbon/epoxy laminates with different stacking sequence. The stacking sequences employed in this study were[0/±45/90]_s, [0/+45/90/-45]_s, [0/90/±45]_s, [±45/0/90]_s, [±45/90/0]_s, [90/0/±45]_s and[90/±45/0]_s. The maximum load of each quasi-isotropic laminate showed a higher value than that of[0_2]laminate. Splitting failure in 0° layer, shear fracture in 45° layer and delamination initiated from the cracks in 90° layer were dominant fracture patterns in quasi-isotropic carbon/epoxy laminates, and their control was important to improve the laminate strength. Especially the suppression of the splitting failure in 0° layer was most important for the improvement of laminate strength because the load bearing capacity of 0° layer was the highest among all layers. The laminates with 0° layer placed at the inner layer showed higher strength because the splitting failure in 0° layer was suppressed sufficiently. The shear fracture in 45° layer initiated from the cracks in 90° layer also affected the laminate strength. The[90/±45/0]_s laminate showed the highest strength among the laminates employed in this study, since the suppression of the fracture in 0° layer and of the fracture progress from the cracks in 90° layer is realized well. From the viewpoint of the suppression of fracture, it was verified that the application of interleaf was effective for the improvement of laminate strength of quasi-isotropic carbon/epoxy laminates.
