Stress-life-temperature extrapolation of the off-axis fatigue data on a cross-ply carbon/epoxy laminate is studied. Off-axis static and fatigue tests are performed on coupon specimens with different fiber orientations at different temperatures. The off-axis tensile behavior of the cross-ply laminate significantly depends on fiber orientation and test temperature. The off-axis fatigue failure of the cross-ply laminate takes place predominantly along the fibers in a brittle manner, regardless of the fiber orientation and test temperature. Straight lines can approximately be fitted to the log-log plots of maximum fatigue stress against the number of cycles to failure for all fiber orientations, regardless of the test temperature.
