The fatigue failure mechanisms of three unidirectional laminated compos ite material systems (consisting of a common fiber in varying resin matrices) were investi gated. Static tensions tests of the pure resins and composites in the axial direction were analyzed in conjunction with fatigue test data to determine failure characteristics. The resins with the highest strain energy density and ultimate strain exhibited the best fatigue properties. A comparison of fatigue curves for both pure resins and composites data showed that the dominant failure mechanism in fatigue is a combination of matrix cracking and interface debonding.
