In this work the effect of heterogeneity in woven composite materials is considered in the context of thermoelastic stress analysis (TSA). The approach is to consider the surface of a woven laminate as a ‘patchwork’ of orthogonally orientated unidirectional fibres. Assuming a state of uniform strain, the global strains are applied locally to predict the thermoelastic response of the woven material. A Cedip Silver IR system is used for the TSA measurements with a standard 27mm lens and a high resolution G1 magnifying lens. Experimental data shows that the strain field is non-uniform and closely related to the weave pattern of the fibre reinforcement. Out of plane deformations are identified as a possible explanation for the deviation between experimental data and theory.
