A cross-section of the plane-woven fiber cloth reinforced plastic laminates was modelled. This model of the cross-section was composed of longitudinal glass fiber crooked thick strands and transverse strands with elliptical cross-section and matrix resin. When the model was loaded the stress state in the model was analysed with F.E.M. (finite element method) On the other hand, photoelastic specimens which had the same geometries and properties as the F.E.M. model were prepared and analysed experimentally. As a result, the cause of debonding between fiber strand and matrix resin was revealed analytically. And results of photoelastic experiments coincided qualitatively well with those of numerical computation by F.E.M. analysis.
