A previously developed fatigue failure criterion for laminae in state of plane stress is used to establish a failure criterion for first fatigue failure of balanced laminates. An extensive tension-tension fatigue testing program for E-glassEpoxy angle-plies with various reinforcement angles has been carried out in order to test the validity of the theory. It has been found that for certain ranges of reinforcement angle there is very good agreement between theory and experiment while for other ranges of reinforcement angle this is not the case.
