Thermoelastic stress analysis of inhomogenous composite materials

Record type: Conference or Workshop Item (Paper)

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.
