Abstract : In order to determine the nature of failure mechanisms a number of fatigue tests were performed. The test specimens partly have artificial delaminations between different layers of the multidirectional laminates made from T300/914C prepregs. For better understanding starting from the free edges between the plies of a multidirectional laminate, has been developed. These defects propagate due to interlaminar stresses up to an area, which is critical in the case of tension-compression fatigue against buckling or shearing of parts of the delaminated test specimen.
