Abstract
Fatigue life of fibre reinforced composite is an important aspect in composite failure investigation. In this paper, master fatigue curve method is adopted to predict fatigue life of unidirectional and braid composite laminate. Different fatigue loading frequency and stress ratios could be used in the master fatigue curve to predict the fatigue life of composite laminate. Equivalent stress is introduced to predict the fatigue life when laminate is under multiaxial stress state. Fatigue life of unidirectional and braid composite laminate predicted by the master fatigue curve show good agreements with experiment.
