The effects of fiber preloads on the ply stresses induced within continuous-fiber compos ite laminates are considered. A micromechanics analysis based primarily upon the rule-of- mixtures is used to predict the fiber and matrix stresses within a single prestressed ply. These results are integrated with classical lamination theory, allowing calculation of the ply stresses for prestressed composite laminates. The analysis indicates that prestressing will dramatically influence the ply stresses induced within composite laminates.
