In this study, the mechanisms governing compressive strength in quasi-isotropic carbon-fiber reinforced-plastic laminates were clarified to gain an understanding of the results of non-hole compression tests. Synchronized observations of both sides of specimens provided insights into the locations of initial fractures in the width directions of the specimens. We also observed the areas surrounding the initial fractures in detail and found that the innermost 0° plies failed under the action of out-of-plane shear deformation. A finite element model was also used to elucidate the factors governing initial fracture. Analytical and experimental results suggest that the occurrence of initial fracture in quasi-isotropic laminates is dominated by out-of-plane shear stress. Based on the results of our analysis, a reasonable sequence of fractures was inferred.
