N2 - This paper deals with the ultimate failure strength of four-layered hybrid laminated composites. A shear-lag model is first applied to obtain the stress redistributions after the breakage of layers. On the basis of the knowledge of these stress redistributions, the probabilistic ultimate failure strength is evaluated by applying the approach of Harlow and Phoenix. The effects on the ultimate strength of hybrid laminates, due to the scatter of lamina strengths, relative fiber volume fractions, composite size and laminate stacking sequence, are identified.
