　　Stress-life-temperature extrapolation of the on-and off-axis fatigue data for a carbon/epoxy cross-ply laminate is studied.Off-axis fatigue tests are performed on coupon specimens with three kinds of fiber orientations q =0, 15 and 45° at different temperatures T =RT, 70 and 90℃, respectively.Fatigue failure of cross-ply laminate specimens takes place predominantly along the fibers in a brittle manner, regardless of the fiber orientation and test temperature.
