Fatigue data of glass epoxy woven laminate specimens cut at different angles to principal axes are reported. The monitoring of changes in the cyclic modulus and hysteresis loop was carried out in all tests. It was found that the final critical damage level before failure, measured as a reduction in the cyclic modulus, did not depend on the durability and was invariant with respect to the loading direction too. Such an invariance of reduction in the final modulus allows one to predict the cyclic durability of investigated material with a reasonable accuracy for any testing angle.
