Off-axis notched strength of a unidirectional CFRP laminate and its fiber orientation and loading mode dependence have been studied. Development of a new engineering method for predicting the off-axis notched strengths in tension and compression is also attempted. Static tension and compression tests were carried out on center hole (CH) specimens with different hole diameters and different fiber orientations. The off-axis tensile and compressive notched strengths are compared to elucidate the loading mode dependence. An anisotropic notch size effect law that takes into account both the effects of fiber orientation and notch size was proposed. Validity of the anisotropic notch size effect law was evaluated by comparing the predicted and observed off-axis notched strengths in tension and compression.
