A method for the fatigue lifetime prediction of composite laminates is discussed. The method is based on the use of normalised fatigue curves obtained by an extensive re-analysis on a large number of fatigue data taken from literature. The available data were divided into several groups according to the following parameters: type of fibre, type of matrix, laminate behaviour, reinforcement architecture and load ratio, found to be those having the greatest influence on the fatigue behaviour of laminates. The main parameters of normalised fatigue curve and scatter band are reported for each group. The accuracy of the method was also verified, with good results, by using data sets taken again from literature.

Abstract
A method for the fatigue lifetime prediction of composite laminates is discussed. The method is based on the use of normalised fatigue curves obtained by an extensive re-analysis on a large number of fatigue data taken from literature. The available data were divided into several groups according to the following parameters: type of fibre, type of matrix, laminate behaviour, reinforcement architecture and load ratio, found to be those having the greatest influence on the fatigue behaviour of laminates. The main parameters of normalised fatigue curve and scatter band are reported for each group. The accuracy of the method was also verified, with good results, by using data sets taken again from literature.
