Abstract [en]

A homogenized analytic model for average moisture uptake in composite laminates containing periodically distributed matrix-cracks is presented. It is shown that the model, compared to FE-calculations, well decribes moisture absorption in a cross-ply composite laminate containing periodically distributed transverse matrix cracks in the 90 degrees plies. The homogenized model is based on a two-phase model consisting of the crack channels and the composite material respectively. An analytic solution to the two-phase model for moisture uptake in composite laminates is presented. The model can be used to judge whether micro cracks are of importance or not concerning moisture absorption.
