A statistical residual strength degradation model for composite materials has been devised in the present paper. It is of great interest to note that the statistical distribution of fatigue life has been derived, from the proposed model, to be a well-known double exponential distribution. The validity of the model has been examined through the comparisons with a sufficient amount of test data for satin woven glass cloth/polyester laminates under subjected to random spectrum loading. Good correlation was verified between the theoretical prediction and the test results of the residual strength as well as its statistical distribution. It is also shown that the model can be easily extended to reflect the engineering reality for other kinds of composite and different loading conditions.
