Models are presented for determination of cure dependent stiffness matrices for composites manufactured with woven fiber mats. Five-harness carbon and eight-harness glass mats with EPON 826 resin composites are considered. The models presented here take into account important material/process parameters with emphasis on: (1) the effects of cure-dependent resin mechanical properties, (2) fiber undulation due to the weave of the fiber fill and warp bundles, and (3) resin interaction with the fiber bundles at a microscopic scale. In the present study these effects are considered in the determination of mechanical properties of a Resin Transfer Molded (RTM) part
