The in-plane thermo-elastic behaviour of woven fabric reinforced composites is analysed using a combination of published micromechanics and finite element techniques. The repetitive unit of an arbitrary woven fabric composite is divided into elements of which the thermo-elastic properties are determined using micromechanics. The properties of the repetitive unit are obtained using the finite element model. The presented model predicts the laminate stiffness and thermally induced forces and moments, from which the thermal expansion and bending coefficients and the residual deformations of the fabric laminate are derived. The theoretical results are validated by experiments on thermoplastic PEI-carbon and PPS-carbon 5H satin weave fabric laminates.
