Abstract: Under generalized loading a method of optimum design for a composite laminate is presented. The optimum ratios of ply groups of laminate satisfying allowable reliability are obtained. The design objective is the weight of laminate and to satisfy the special requirement of laminate. It is shown by examples that this method is very efficient.

Key words: composite laminate, reliability, optimum design of laminate layup
